The idea of continental drift was not proposed until the 1960s, when the first evidence to support it was discovered. True False
Answer:
False
Explanation:
The theory of continental drift was first proposed by geophysicist Alfred Wegener who believed that due to origin from same continent million years back, animal and plant species in current time though located on different land parcel have similarity in some or the other way.
However, after the acceptance of plate tectonic theory and series of magnetic surveys conducted in 1960, the idea of theory of continental drift strengthened and the wegner's theory was rectified as he proposed that continents do not originate from the ocean surface.
Hence, the given statement is false

You are working in a group taking sediment samples along a transect from a beach, into deeper water. Someone forgot to label the jars and they got mixed up so it is now not clear which sample came from which location. Based on what you know about particle size and transport, how can you arrange the samples in the correct order
Answer:
It is commonly known that the settling time of particles with smaller sizes is higher than that of particles with larger sizes. Therefore, the particles with smaller sizes are moved further offshore. Based on this fact, the proper arrangement will be to arrange the particles according to their sizes from those with the largest sizes (nearshore) to those with the smallest sizes (furthest offshore).

Which rocks would be likely to contain olivine. Select one or more: a. basalt b. andesite c. gabbro d. granite e. peridotite
Answer:
Correct option are Basalt, gabbro and peridotite.
Explanation:
Igneous rocks like basalt, gabbro, dunite, diabase, and peridotite contains the olivine mineral. These are the dark coloured rocks and found within the surface of earth mostly in the areas around the tectonic plates. Olivine is known for its crystallization at high temperatures. It crystallize itself from the heat of the earth. Common olivine minerals are Forsterite, Fayalite, Monticellite and Tephroite.
Basalt, gabbro, and peridotite are rock types that would be likely to contain olivine due to their mafic or ultramafic composition, where olivine is commonly found.
Explanation:The rocks which would be likely to contain olivine are predominantly mafic or ultramafic in composition, due to olivine being a mineral commonly found in such rock types. This would include rocks such as basalt (a), an extrusive igneous rock that is fine-grained and dark-colored; gabbro (c), an intrusive counterpart to basalt that is coarser in texture; and peridotite (e), an ultramafic rock with a high percentage of olivine content. It should be noted that while andesite (b) and granite (d) can have some of the same minerals as those rocks that contain olivine, they are generally considered felsic rocks and are less likely to contain significant amounts of olivine.

what two factors lead to high crop yields in europe's agriculture
Answer:
Soil and fertilizers
Explanation:
beacuse these two factors will lead the crops to grow faster...
Answer:Temperature and Rainfall
Explanation:
Temperature : Most plant cannot grow if temperature falls below 6degree celcius or the soil is frozen for five consecutive months.
Rainfall: Water is obviously a key factor in plant growth. The greater the average temperature, the greater the amount of water required for plant growth. Seasonal crops require water at different times.
These are the aforementioned factors that leads to high crop yield in Europe.
Why do areas of high altitude (e.g., on the Tibetan plateau) have greater than expected UV intensity and areas of constant cloud cover (e.g., Congo Basin) have less than expected?
Explanation:
UV (ultraviolet) levels are high in the areas of high altitudes. Tibetan plateau being the highest plateau of the world is more exposed to the UV radiations as the atmosphere gets thinner in the areas of higher altitude. So it can not filter the maximum of ultraviolet radiations. Tibetan plateau is on 4,500 meters height and the UV level increase by 10-12% upon every 1000 meter elevation.
However in those areas having the constant cloud cover like in Congo Basin the UV level is low as the clouds scatter the most of the UV radiations and they particularly stop the UV-B radiations. Thats why the cloudy areas have less UV level then the areas having a cloudless clear sky.
Final answer:
The increased UV intensity at high altitudes is due to the thinner atmosphere and reduced water vapor content, which allows more UV radiation to reach the surface. In contrast, areas with constant cloud cover experience less UV exposure due to the clouds' reflection and absorption of UV radiation.
Explanation:
The variation in UV intensity at high altitudes such as the Tibetan plateau can be attributed to several factors. Firstly, high altitudes experience less atmospheric interference, meaning there is a thinner layer of atmosphere for the UV rays to penetrate through - leading to a greater intensity of UV radiation reaching the surface. This phenomenon is partly due to the fact that water vapor, which absorbs UV radiation, is less prevalent at higher altitudes. Additionally, the ozone layer, which absorbs a significant amount of UV radiation, particularly harmful UVB and UVC, is less effective with increasing altitude, letting through more UV radiation.
Conversely, in areas with constant cloud cover, such as the Congo Basin, UV intensity is generally lower. Clouds reflect and absorb UV radiation, limiting the amount that reaches the Earth's surface. Moreover, the moisture-heavy atmosphere associated with cloudy regions further reduces UV penetration. The persistent cloudiness acts as a protective barrier, shielding the surface from direct UV exposure.

ice sheet contains 3 million cubic kilometers of ice. if completely melted, this ice would release about 2.7 million cubic kilometers of water, which would spread out over earth's approximate 337 million square kilometers of ocean surface. how much would the sea level rice
Answer:
8.011 m
Explanation:
Data provided in the question:
Volume of the ice sheet = 3 million cubic kilometers
Volume of the water released by the ice on melting = 2.7 million cubic kilometers
Approximate area of the Earth's ocean surface = 337 million square kilometers
Now,
Volume = Area of the surface × Height
thus,
2.7 million cubic kilometers = 337 million square kilometers × Height
or
Height = 2.7 ÷ 337 kilometer
= 0.008011 kilometer
also,
1 kilometer = 1000 meter
Therefore,
Rise in the sea level = 0.008011 × 1000
= 8.011 m

The search for black holes has so far turned up some fairly convincing stellar-sized candidates in binary star systems. What observations could you make to distinguish whether the unseen object in one of these systems is a black hole or a neutron star?
Answer:
Th similarities between the black hole and the neutron star is that they are formed from dead (dying) starts. But they come from different parent stars, if the parent star is 1.4 times the mass of the sun, a neutron star will be formed, but if the parent star is twice the mass of the sun a black hole is formed.
Explanation:
A black hole is defined as an area of space whereby the matter is so compacted that nothing can escape from it. This area is called event horizon. Black holes are formed when an enormous star dies in z supernova. They weigh at least twice the sun's mass, and their mass is directly proportional to their radii.
Neutron stars are created during supernova and maintained by a neutron called degeneracy pressure. Neutron star has a small radius, typically 30 km, with a very high density made up of compacted neutrons.
Climate is highly variable but weather is not. Weather varies over long periods - decades or more. True False
Answer:
This statement is false.
Explanation:
The difference between climate and weather is dictated by the period of time over which atmospheric conditions are measured. When conditions in the atmosphere are measured over a short period of time, it is called weather. When behaviour of conditions is measured over a longer period of time, over years, decades and even centuries, it is called climate. Because it is measured over shorter periods, weather tends to be more variable than climate where climate shows changes over long periods of time.

Explanation:
Imagine that biostimulation is used on a widespread scale for a bioremediation project.
What ecosystem changes represent a potential side effect of the cleanup efforts?
Answer:
Explanation:
The biostimulation can be define as the process of modifying the environment by the stimulating the growth of bacteria which are capable of conducting the bioremediation. The bioremediation is the process through which the microorganisms are used to break down and decomposed the environmental pollutants from the polluted site.
This can be achieved through addition of the nutrients and electrons acceptors like nitrogen, oxygen, phosphorus and carbon in the from of molasses. These factors are likely to enhance the growth of the bacteria to an extent that can damage the organisms of the ecosystem or the growth factors can be also suitable for the growth of other microorganisms which may infect the other living beings of the ecosystem.
Final answer:
Biostimulation used in bioremediation may lead to disruptions in microbial ecosystems, affecting biogeochemical cycles and plant health, as well as possible biomagnification of biological agents, resulting in health issues for wildlife and humans.
Explanation:
When biostimulation is employed on a widespread scale for a bioremediation project, there are potential ecosystem changes that could occur as side effects. One potential side effect is the disruption of the natural microbial taxonomic distribution and functional profiles which could lead to changes in biogeochemical cycling and overall plant health. Another concern is the possibility of biomagnification, where the biological agents used for cleanup might accumulate in the food chain, potentially leading to issues such as endocrine disruption, birth defects, and other health impacts on both wildlife and humans.
An example of bioremediation is depicted by option E: Using plants to remove toxic metals from soils following a mining operation, which is a type of phytoremediation. This process can sometimes alter soil structure and nutrient cycling, potentially affecting other ecosystem services and biodiversity. These changes could have short-term effects, such as altered hydrology and productivity, or long-term impacts, which might include shifts in the types and numbers of species found in an ecosystem.
Which of the following sites would have the most dangerous volcanoes? A is on an island arc, B is in the Andes, C is near Hawaii, D is along a mid-ocean ridge.
Answer:A
Explanation:On the island arc
The most dangerous volcanoes are likely to be found at Site A. located on an island arc, due to the process of subduction which leads to more explosive eruptions.
Explanation:The level of danger posed by a volcano largely depends on its location and the type of magma it produces. Considering the given locations - an island arc, the Andes, near Hawaii, and a mid-ocean ridge - Site A located on an island arc would most likely host the most dangerous volcanoes.
This is due to the process of subduction which is common at island arcs: one tectonic plate slides underneath another, creating a significant amount of magma, which can lead to explosive eruptions when it reaches the surface. On the other hand, volcanoes in the Andes and near Hawaii tend to be less explosive, typically resulting in more predictable, slower moving lava flows. The mid-ocean ridge volcanoes, such as at Site D, are usually the least explosive as they occur underwater and their eruptions are therefore less likely to impact human populations.

The Earth formed its compositional layers (core, mantle, crust, atmosphere) by accretion in stages: first iron-rich materials, followed by rocky materials, and finally by ices.
Answer:
As described below.
Explanation:
The earth has core is the innermost layer and is made up of iron, nickel, and alloy rich content and is about 2,900 to 5100 km in depth, has a surface temperature that goes up to 5700 K and is responsible for producing the magnetic waves and the semis waves. And there is the densest part of the planet, followed by the cover of the mantle that is made of silicate rocks and ice and planetary layer that undergoes differential density and has a thickness of 2,900 km and is divided into the three layers of the upper, middle and the lower. The uppermost layer is called the asthenosphere and forms the base of the oceanic crust followed by the lithosphere crust. That is igneous, metamorphic and the sedimentary ricks and has a density of 2.83 g/cm.Final answer:
The Earth's layers formed by accretion in stages with gravity separating materials by density, creating the core, mantle, and crust. This process is known as differentiation.
Explanation:
The statement that the Earth formed its compositional layers (core, mantle, crust, atmosphere) by accretion in stages, with iron-rich materials first, followed by rocky materials, and then ices, is true. During the formation and early history of Earth, gravity played a crucial role in separating materials based on their densities. The denser materials, such as iron and nickel, sank to form the Earth's core, while lighter materials rose to the surface to eventually form the crust. This process, referred to as differentiation, led to the creation of distinct layers including the core, mantle, and crust. Earth's atmosphere formed later, consisting of gases that were either released from volcanic eruptions or delivered by cometary impacts. The Earth's structure today is the result of these processes, where the crust is primarily made of lighter elements like silicon, oxygen, and aluminum, the mantle consists of heavier rocks, and the core is composed mostly of iron and nickel.

From a sample with nequals36, the mean duration of a geyser's eruptions is 3.16 minutes and the standard deviation is 0.82 minutes. Using Chebyshev's Theorem, determine at least how many of the eruptions lasted between 0.7 and 5.62 minutes.
Answer: -3.154 eruptions lasted for 0.7mins and 1.767 eruptions lasted for 5.62mins
Explanation:
The attachment below shows the explanation and how to determine the duration of each eruptions.
Using Chebyshev's Theorem, at least 88.9% (or around 32) of the sample of 36 geyser eruptions would last between 0.7 and 5.62 minutes.
In statistics, Chebyshev's Theorem allows us to predict the proportion of data that falls within a certain number of standard deviations from the mean. The theorem states that at least 1 - 1/k^2 of the data lies within k standard deviations of the mean for all k > 1.
In this case, the mean duration of a geyser's eruptions is 3.16 minutes, and the standard deviation is 0.82 minutes. The interval of 0.7 to 5.62 minutes is roughly calculated to be minus 3 and plus 3 standard deviations from the mean. According to Chebyshev's Theorem, at least 1 - 1/3^2 = 8/9 or 88.9% of the data falls within this range.
As we know the total sample size is 36, we then calculate 88.9% of 36. It results in around 32 geyser eruptions that would last between 0.7 and 5.62 minutes.

Seismic resonance is responsible for the damage caused to building by earthquakes. Apply the concepts of wave energy and resonance to explain how earthquakes damage the man-made structures.
Answer:
The building will vibrate around one particular frequency known as its natural, frequency, the building and ground share the building frequency its said to be in resonance.
Explanation:
Resonance is the frequency of the system to oscillate with a greater velocity than the others as all buildings have a resonance period which is the number of seconds for a building to vibrate and the ground also shows the seismic resonance frequency, the mismatch of the resonance and the wave frequency. Thus taller buildings will be damaged more than shorter structures. These forces create the lateral accelerations that scientists measure by the G-forces. The sudden movement creates enormous stresses for the building's structure, including the beams, the columns, and the walls and the floors, as well as the joints that hold them together. If that stress is large enough, the building can collapse.Answer:
Earthquakes produce traveling mechanical waves known as seismic waves. These waves propagate by vibrating the ground (solid media), water, and to a lesser degree the air, in areas surrounding the epicenter of the earthquake.Energy from the waves also produces vibrations in buildings. If the frequency of the vibrating ground matches the natural frequency of the building, resonance is produced in the form of standing waves that amplify the vibration to levels that can destroy the structures.

Describe radiometric dating and discuss three prerequisites that must be met in order to obtain a reliable radiometric date on a granite batholith. What are the various methods of radiometric dating that may be used?
Answer:
Radiometric dating is usually defined as a method that helps in calculating the age of rock depending on the presence of radioactive isotopes and its rate of decay. In order to calculate this, the half-life of the isotope element must be known. This method is commonly used by geologists.
The conditions that are needed to fulfill in order to determine the age of a granitic batholith are as follows-
The rate at which these materials decay must be a constant There should be an exact amount of both the parent as well as the daughter elements. Since it is a batholith, so it has formed from the crystallization of magma at a certain depth. So, these granitic rocks must have remained within a closed system, right from the time of its formation.The various methods of radiometric dating that can be used to date this granitic batholith are-
Uranium-lead dating- It is an efficient method to date the rocks that are of about 4 to 4.5 billion years. Potassium-argon dating- It is also commonly used to date rocks that are about 4 billion years old.Final answer:
Radiometric dating uses the decay of radioactive isotopes to date rocks and fossils. Three prerequisites for accurate dating include starting with no daughter isotopes, the rock being a closed system, and a consistent decay rate. Various isotopes, such as Uranium-238 to Lead-206, are used for dating.
Explanation:
Radiometric Dating in Geology
Radiometric dating is a technique used by geologists to determine the absolute age of rocks, minerals, and fossils by measuring the decay of radioactive isotopes within them. Three prerequisites for obtaining a reliable radiometric date on a granite batholith are:
Initial Condition: When the rock formed, it must have contained no daughter isotopes, ensuring all measured daughter isotopes came from radioactive decay.
Closed System: Since formation, the rock must have remained a closed system, meaning no parent or daughter isotopes were added or removed.
Consistent Decay Rate: The decay rate of the radioactive isotopes used for dating must be known and constant over time.
Various methods of radiometric dating include using isotopes such as Uranium-238 decaying to Lead-206 for dating very old materials. This U-Pb dating reveals that the oldest rocks on Earth solidified around 3.5 billion years ago. Other radioisotopes may also be used depending on the material and the time period being studied.
