Answer:
C. The volcanic activity
Explanation:
The Devonian period is the period in which the diversification of life exploded. The fish types increased significantly, while the plants started to develop proper roots and grew much larger. Also, in this period we have the formation of the first soils.
As a period it has been relatively cold, and the main reason for that are the plants because they extracted large amounts of carbon dioxide from the atmosphere. By the end of this period though, large volcanic eruptions occurred, and through them, lot of carbon dioxide was released into the atmosphere, warming up the planet for few degrees and changing the climate.
The volcanic activity released large amounts of carbon dioxide at the end of the Devonian period. Hence, option (C) is correct.
This process significantly impacted the global climate, contributing to mass extinction events.
At the end of the Devonian period, about 350 million years ago, significant geological and biological changes occurred, including increased volcanic activity.Volcanic eruptions released large amounts of carbon dioxide (CO₂) and other gases into the atmosphere.This surge in CO₂ may have reduced the greenhouse effect initially but eventually led to sustained climatic changes.The volcanic activity released CO₂ that would have contributed to atmospheric warming, altering the Earth's climate.In conclusion, volcanic activity played a crucial role in releasing large amounts of carbon dioxide at the end of the Devonian period, impacting the global climate and contributing to the mass extinction events.

Answer:
French Guiana
Explanation:
_______ is the point where some region of the lithosphere reaches its ultimate elevation and stops rising. A. Orogeny B. Isostatic equilibrium C. Buoyancy D. Isostatic uplift
Answer:
B. Isostatic equilibrium
Explanation:
Isostasy is a state of balance or equilibrium between the lithospheric plate and the underlying mantle, the asthenosphere.
Due to the weight of the lithosphere, part of it sinks into the plastic asthenosphere and settles to an equilibrium position. This is what causes changes and differences in elevation on the earth.
As with all natural processes, the earth in itself tries to achieve stability and equilibrium in all it parts. The crust and a portion of the mantle forms the brittle lithosphere. The lithosphere floats on the plastic mantle. Due to density contrast, portions of the lithosphere tends to sink into the mantle from time to time. The lithosphere reaches a point where it no longer sinks and establishes an equilibrium with the asthenosphere.
This isostatic adjustment that occurs within the earth is responsible for the changes in elevations from places to places.
When portions of the crust gets eroded, it becomes lighter and rises up. When materials are deposited in adjacent areas or glaciers forms, they add increasing weight to the crust and causes it to further settle within the asthenosphere.
Answer:The two competing ideas in _______ were formulated by the English mathematicians John Pratt and George Airy.
Due to the thick and viscous material in the asthenosphere, the liquid is called _______.
_______ is reached when areas of the lithosphere stop rising.
A change in density occurs as a result of _______ compression.
Respond to the following based on your reading.
What happens in the theory of isostasy?
Explanation:answer::plate tectonics
viscoelastic
isostatic equilibrium
asthenosphere
This theory explains how the tectonic plates in the lithosphere able to move freely on the asthenosphere. The lithosphere is less dense than the asthenosphere. There is an equilibrium of the buoyancy between the lithosphere and asthenosphere.
Write a characteristic of the photic zone of a freshwater biome.
Characteristics of the photic zone in the freshwater biome are the warmer water, light, rich in freshwater organisms, shallow.
The photic zone is the first zone from the top of the freshwater body of water. It is the shallowest part of the body of water, and it is further divided into the littoral zone and limnetic zone. This zone is the closest to the shore. The sunlight manages to penetrate in it, so it is a zone where the majority of the producers are able to survive and thrive because they can perform the process of photosynthesis. Since this zone enables the producers to thrive, and the producers are the basis of any ecosystem, it enables the further existence, high diversification, and thriving of all the other living organisms in the freshwater biome. The photic zone is also characterized with warmer water because it is on the top, it is heated by sunlight, so that provides nice conditions for the living organisms to be the most abundant in this zone.

1. giant impact forms moon
2. end of heavy bombardment
3. early life (based on fossil evidence))
4. oxygen buildup in atmosphere
5. earliest mammals
6. dinosaurs go extinct
7. earliest humans
Explanation:
The Earth has a very interesting past, with lot of changes and turnarounds in it. If we sum it up quickly, we can say that soon after the Earth formed and collided with another large space object, part of the Earth was torn away, which eventually formed the moon. The Earth was constantly bombarded by meteorites and asteroids, but that came to an end as the atmosphere was becoming denser and denser. The first life started to develop in the oceans in the form of cyanobacteria, which used photosynthesis, and were constantly releasing oxygen, building it up int he atmosphere. The oxygen changed the living conditions, enabling the life to thrive and diversify. The dinosaurs and mammals eventually came on the scene, with the dinosaurs coming first by around 20 million years, giving them the edge to become the dominant life form. The mammals lived in the shadows until the dinosaurs existed, but their reign ended with a large meteorite collision. This prompted the quick evolution and diversification of the mammals, quickly becoming the dominant life form, and just few million years ago they gave rise to the earliest human ancestors, the hominids.
What feature is an inlet of the Indian Ocean that lies between Africa and Southwest Asia?
Arabian SeaRed SeaStrait of Hormuz
Answer:
Red Sea
Explanation:
The Red Sea is the outlet of the Indian Ocean that lies between the northeastern part of Africa and Southwest Asia. This sea is one of the two northernmost points of the Indian Ocean along side the Persian Gulf. The Red Sea is a long be very narrow sea, having a northwest-southeastern direction. The sea is known for two things, having the warmest waters, and having the highest salinity. Both of those things are connected. The high temperature of the water is because the sea is surrounded by two of the biggest deserts in the world, the Sahara desert on the west, and the Arabian desert on the east. Both of them are very dry and very hot, so the sea trapped between them has very warm water as well. Because the temperature is high, the evaporation is very high as well, leading to higher concentrations of salt in the water, thus making it a very saline sea.
What are some things that are unique about harlem
Answer:
the Harlem Renaissance and more and more black writers, artists and other intellectuals began moving there.
Explanation:
Final answer:
Harlem was a vital center for the cultural expression and innovation of African Americans during the Great Migration, largely known for its pivotal role in the Harlem Renaissance. It was home to jazz music, literature, and fashion that have had a lasting influence on American and global culture.
Explanation:
Harlem, a three-square-mile sector of Manhattan, became a significant destination for African Americans during the Great Migration. This culturally rich neighborhood was the epicenter of the Harlem Renaissance, a major cultural movement where African American artists, writers, and entertainers flourished. Harlem was an artistic center producing literature, music, and fashion that defined American culture and 'cool' during the 20th century. Notables like Langston Hughes expressed their identity with pride, advocating for the expression of the 'dark-skinned selves without fear or shame.' The remarkable energy of the Harlem Renaissance fostered a sense of racial pride and contributed to a new perception of African Americans, challenging racist stereotypes.
Jazz music especially became synonymous with the Harlem Renaissance, with legendary artists like Duke Ellington and Cab Calloway performing at famous venues such as the Cotton Club. The jazz age signaled an era of innovation and cultural integration. The Renaissance's impact extended globally, influencing music, literature, and art worldwide. Despite the setback of the Great Depression, the legacy of the Harlem Renaissance continues to illuminate the talents and capabilities of Harlem's residents and the broader African American community.
Metallic minerals are most commonly associated with ____________ rocks
Answer:
Igneous and Metamorphic rocks
Explanation:
As metallic ores are found in every rock type. These get concentrated into the earth through the formation of basaltic lavas and further these minerals upon solidification from rocks of metallic nature and have magnetic properties associated with them. Metamorphosed rocks have deposits of lead, magnesium, copper and iron and other heavy metals. Various gemstones also bear this type of element that is supposed to have occurred at the time of the formation of earth core and mantel. Some were formed from aluminum and others by sandstone as due course of time extreme pressure and heat melted to form these deposits."The correct answer is igneous rocks.
Metallic minerals are most commonly associated with igneous rocks. This is because the process of magma crystallization, which leads to the formation of igneous rocks, can concentrate minerals into economically viable deposits. When magma cools, either beneath the Earth's surface (intrusive) or on the surface (extrusive), it can form a variety of igneous rocks. During this cooling process, minerals can crystallize and, depending on the conditions, may form large deposits that are rich in metallic minerals.
Igneous processes can lead to the concentration of minerals in several ways:
1. Fractional crystallization: As magma cools, different minerals crystallize at different temperatures. Early-forming minerals may settle out of the magma, leading to a concentration of other minerals, including metallic ones, in the remaining liquid.
2. Magmatic differentiation: This process involves the separation of magma into layers of different compositions, which can lead to the formation of mineral-rich layers.
3. Pegmatite formation: These are extreme examples of fractional crystallization where the final stages of magma crystallization can form large crystals of minerals, including metallic ones.
4. Hydrothermal processes: Hot fluids circulating through fractures in igneous rocks can deposit minerals, including metallic ones, in veins and disseminated ore bodies.
Sedimentary rocks can also host metallic minerals, but these are typically formed through different processes, such as sedimentary deposition and diagenesis, which can concentrate heavy minerals, including some metallic ones, in placer deposits. Metamorphic rocks may also contain metallic minerals, often as a result of metamorphism of pre-existing igneous, sedimentary, or other metamorphic rocks that already contained the minerals. However, the primary association of metallic minerals is with igneous rocks due to the direct involvement of magmatic and hydrothermal processes in their formation and concentration."

Imagine you are an astronomer who recently discovered a new planet orbiting a distant star.
Which set of characteristics would you use to classify this planet as an inner or terrestrial planet? Check all that apply.
-dense and solid
-very large
-thick atmosphere containing hydrogen and helium
-lacking a solid surface
-located near a star
Answer:
- dense and solid
- located near a star
Explanation:
Inner planets or terrestrial planets are considered to be smaller when compared to outer planets such as Jupiter, Saturn, Neptune and Uranus.
They are called terrestrial planets because they are characterized by having solid, rocky surface which is like desert and mountainous areas of the earth.
Example of inner planets aside planet Earth are:
1. Mercury
2. Venus
3. Mars
Inner planets are formed as a result of gravitational attraction which caused inner rings of material to accumulate and form massive rocks and heavy elements.
Also, astronomers speculate that, near the sun, are the heavier elements compacted. Elements such as iron and nickdel, whereas far away from the sun are elements such as methane, hydrogen and water condensed.
Therefore, to determine if a planet is inner and terrestrial it must have the following characteristics:
1. Rocky surface
2. Smaller in size
3. Located near a star.
4. How does trade affect the minerals found in the earth's crust?
A. Trade gives power to those countries who need resources.
B. Trade equalizes the resources found in the earth's crust by allowing for greater distribution.
C. Trade blocks the redistribution of resources.
D. The only goal of trade is to widen the imbalances between rich and poor countries.
Answer:
B. Trade equalizes the resources found in the earth's crust by allowing for greater distribution.
Explanation:
Trade is the transfer of goods and services from one place to another. Trade is a means of exchange of goods and services in a place.
Earth resources are not evenly distributed across the earth. A host of geologic factors affects how natural resources are distributed in the subsurface. Some countries have vast deposits of resources while others are lacking. Some countries have more than they can use.
Since no country is an island on its own, trade guarantees the distribution of naturally occurring resources in return for other rewards. Oil in the middle East for example is highly coveted by the Western world and America, it is influential to their vast industrialization ambition and drive. Uranium from Niger Republic is very important for power generation in France. Some rare earth metals in Congo are used as component for making mobile phones and electronics, it is exchanged for other pressing resources. Trade is what facilitates this exchange.
The value of a good is measured up and the equivalent is returned back.
Answer:
B. Trade equalizes the resources found in the earth's crust by allowing for greater distribution.

open
wobbling
I believe it's globular and open are the main types.
Answer:
globular, open
Explanation:
A star cluster is a group of stars that are gravitationally bound and these tend to form old and the new stars. Hence the three main types of the star clusters are that of the globular, open and that of the apparent that are generally found n the core of the galaxy that may be halo or spiral or elliptical. The globular clusters have stars occurring in about 50 to 450 light-years from the other stars and are millions of years old arranged in their gravitational bounds, while the open clusters are those of the loosely and open spaced stars that are distributed over the time by the molecular clouds in the galaxy. The globular clusters are distant in the galactic halo and are orbiting in there highly elliptical orbits at the time may lead to the super star clusters. Whereas the open clusters are confined to the galactic plane with spiral arms.Why do we see a gravitational redshift in the spectrum of the sun?
Answer:
When we talk about the visible electromagnetic spectrum, we know it starts in violet-blue and ends in red.
In this context the astronomer Edwin Powell Hubble observed several celestial bodies, and when obtaining the spectra of distant galaxies he observed that the spectral lines were displaced towards the red one (red shift), whereas the nearby stars showed a spectrum displaced to the blue one.
From there, it was deduced that the farther a body in the universe is, the more redshifted it is in its spectrum. This effect is due to the dilation and contraction of time by speed according to the relativity.
Now, the Sun is a massive star and the Earth is at certaind distance from it, therefore time passes slower in the Sun than on Earth. This causes the spectrum of the Sun to present lines with a lower frequency or longer wavelength than normal, that is, more towards red.

The continental crust is thicker than oceanic crust, averaging about 35 kilometers in thickness, and is composed mainly of light silicates like granite, making it less dense and causing it to rise higher above the mantle. It is also thicker below mountains due to deep roots extending into the mantle.
The continental crust is significantly thicker than the oceanic crust. It has an average thickness of about 35 kilometers, although this varies considerably. The composition of the continental crust predominantly includes igneous, metamorphic, and sedimentary rocks, with granite being the most common.
Granite consists largely of silicates made of silicon and oxygen, making it less dense compared to the mafic rocks like basalt found in the oceanic crust.
Furthermore, due to the lower density and greater thickness, the continental crust rises higher above the mantle than the oceanic crust. It is also thicker below mountains than below valleys because mountains are supported by deep roots that extend into the mantle, known as isostasy.

How do the oceans contribute to maintaining a climate that is habitable for humans?
The oceans are one of the major elements that influence the climate around the globe. They are massive water bodies, being able to accumulate and release enormous amounts of gasses from and into the atmosphere. Also, the ocean waters are an excellent heat storage, as the water has a property to cool down and warm up relatively slowly, so once its warmed up it tends to keep the temperature much higher at the places near the coast. The ocean waters are constantly on the move because of the difference in temperature and density. With the movement of the water they create air masses that follow them, some warm and wet, some cold and dry. The places that are influenced by the oceans have their climates modified mostly by them, with the most common characteristic being that the temperatures extremes are lacking, so the climate tends to be milder in all seasons, or at places it remains the same for the whole year.

What are some different phases of climate the earth has gone through?
Answer:
- Warm and wet
- Glaciation
- Inter-glacial
Explanation:
The climate on Earth has been changing constantly. There have been numerous changes, some of which gradual, some dramatic, with the causes for it being multiple. Some geological periods have been very warm and wet, with the temperatures being constantly high, and the amount of precipitation also being high. Some periods have experienced significant cooling, with ice caps stretching far away from the poles, temperatures much lower, and generally drier climate. In between these two extremes are the inter-glacial periods. They are neither very warm nor very cold, but in general more moderate when compared to them. The temperatures and precipitation are arranged by latitude, and some places are warm and wet, others hot and dry, some have seasons, while some are very cold and dry.
How do volcanoes form at divergent boundaries?
The divergent plate boundaries are the places where the tectonic plates move away from each other. As they move part, which is actually driven by the convection currents in the mantle, they leave a gap between them of very thin and cracked crust. The convection currents manage to push the magma up with easy through this gap. As the magma pushes upward, it reaches the ocean floor, where the temperatures is significantly lower and it quickly cools off and forms new igneous rocks, or rather new crust. Since the magma is constantly rising and constantly making new crust, the new crust is pilling up, forming a mid ocean ridge with intense volcanic activity. Eventually, the rising magma will manage to come out on the surface and create volcanic islands, thus a chain of volcanic islands, which can even result in the formation of new large land of mass.
Volcanoes form at divergent plate boundaries through decompression melting, where the upwelling mantle magma rises through gaps created as tectonic plates move apart. This process creates new crust and can lead to the development of shield volcanoes, as seen in Iceland and mid-ocean ridges.
Formation of Volcanoes at Divergent Boundaries
Volcanoes form at divergent plate boundaries when the Earth's tectonic plates move apart, creating a gap. As the plates separate, magma upwelling from the mantle fills this space and is forced through the cracks, leading to the creation of a new crust. This process is known as decompression melting and is significant along mid-ocean ridges like the Mid-Atlantic Ridge. A notable example of volcanic activity at a divergent boundary is the island of Iceland, where the upwelling magma has created numerous volcanoes.
Shield volcanoes are a common type of volcano that forms along divergent boundaries, as well as over mantle hotspots. Characterized by their mafic (basaltic) magmas, shield volcanoes typically have gentle slopes and non-explosive eruptions, as seen in regions such as Hawaii, which is situated over a hotspot.
Overall, divergent plate boundaries produce significant geological disturbances, including the continual formation of mid-ocean ridges and related volcanic activity. This process is fundamental in shaping the Earth's surface and creating the landscape of the ocean floor.
