Answer:
B. Large buildup of pressure from gases
Explanation:
The composite volcanoes are volcanoes that are characterized with felsic magma. This type of magma is highly to intermediately viscous. The silica content is high. This results in much denser magma that manages to trap the gases in it instead of them living freely into the atmosphere. As the magma comes toward the surface, the temperature and pressure change significantly, so the built up gases in it manage to cause strong explosion, which in turn results in explosive and effusive eruptions of these volcanoes.
texture of shape of a mineral surface when broken
When a piece of Halite is broken, it breaks into many smaller cubes. when a mineral breaks into jagged edges. Some minerals have no planes of weakness, so they have no cleavage. Crystal Shape is the natural geometric shape of a mineral.
Hope this helps :)
The texture of a mineral surface when broken is determined by its cleavage, which produces smooth flat surfaces along planes of weakness, or fracture, which results in irregular, jagged surfaces. Close examination with a hand lens is vital for accurate identification.
The texture of the shape of a mineral surface when broken can be determined by its cleavage or fracture. Cleavage refers to the way some minerals break along certain planes of weakness to produce smooth, flat surfaces. These planes are created due to weak bonds in the mineral's structure, allowing it to split easily along them. On the other hand, fracture describes the breakage of minerals along irregular surfaces when there are no planes of weakness. This results in uneven, sometimes jagged surfaces that do not follow a predictable pattern. To accurately identify whether a mineral displays cleavage or fracture, close examination using a hand lens is often necessary, as it allows for the observation of subtle surface details that indicate the nature of the mineral's internal structure.
Which of the following geological features can form at a subduction zone? A. Volcanism and mountain ranges B. Mid-ocean ridges C. Mantle convection D. Magnetic anomalies
Answer: The correct answer is Volcanism and mountain ranges.
Explanation:
Whoever said the answer is Mid-ocean ridges is incorrect. Choose wisely!
A. Volcanism and mountain ranges.
Volcanism and the formation of mountain ranges are intricately linked to the dynamic processes occurring at subduction zones, where tectonic plates interact in a compelling geological dance. At these convergent boundaries, one tectonic plate is compelled to descend beneath another, setting the stage for a cascade of geological phenomena.
At a subduction zone, one tectonic plate is being forced beneath another. This process can lead to the formation of volcanic arcs (volcanism) and mountain ranges. The descending plate can melt and create magma that rises to the surface, resulting in volcanic activity. Additionally, the intense tectonic activity at subduction zones can lead to the uplift of crustal rocks, forming mountain ranges. Therefore, option A is the correct answer

9. Topographical map - Elevation is indicated by the distance between lines
10. Winkel Tripel projection - Reduces distortion of distance, direction, and area
Explanation:
To complete this activity we need to understand the concepts of each of the geographical tools given
1. Atlas - An Atlas is a collection of maps of Earth, or a region of Earth. They present geographic features, political boundaries, and often geopolitical, social, religious and economic statistics.
2. GIS - Stands for Geographic Information System or Science, is a computer system for gathering, managing and analyzing spatial or geographic data. It can show many different kinds of data on one map, such as streets, buildings, vegetation, etc. Which allows people to see more easily, analyze and understand patterns and relationships, helping users make smarter decisions.
3. Globe - It is a spherical model of Earth or celestial body. Globes do not distort the surface that they represent, only to scale it down, but the proportions remain faithful.
4. GPS - stands for Global Positioning System, and is global navigation satellite system which provides geolocation and time information to a receiver anywhere on earth. The GPS provides critical positioning capabilities to anyone with a GPS receiver.
5. Mercator projection -It is a cylindrical map projection which became the standard map projection for navigation as it represents any course as a straight segment. The Mercator projection inflates the size of objects away from the equator, and shows objects far larger than they actually are as they get closer to the poles.
6. Political map - Political maps are designed to show the boundaries of countries, states, the location of major cities. Different colours are often used to differentiate between nations.
7. RADAR - It is a detection system using radio waves to determine the range, angle and speed of objects. It's often used to detect aircraft, ships, spacecraft, missiles, weather formations and terrain. In navigation it's often used to identify obstacles in the route when there is low visibility.
8. Relief map - It is a three-dimensional representation usually of terrain. The layers of the terrain are overlaid with a color map to make it more realistic
9. Topographical map - Is a map that shows in large scale a representation of relief, using contour lines. A contour line is a line connecting places of equal elevation.
10. Winkel Tripel projection - It is a map projection of the world which minimizes three kinds of distortion: area, direction and distance. The equator and the poles are straight lines, while all other parallels are curved.
What are the consequences of increased nitrogen and phosphorus into water systems?
Nutrient pollution has impacted many streams, rivers, lakes, bays and coastal waters for the past several decades, resulting in serious environmental and human health issues, and impacting the economy. Too much nitrogen and phosphorus in the water causes algae to grow faster than ecosystems can handle.
What are two sources of increased nitrogen and phosphorus in a river that result from human activity?
Phosphorus (P) and nitrogen (N) are the primary nutrients that in excessive amounts pollute our lakes, streams, and wetlands. Nitrogen is essential to the production of plant and animal tissue. It is used primarily by plants and animals to synthesize protein.
What happens if there is too much nitrogen in an aquatic ecosystem?
Excess nitrogen can harm water bodies. Excess nitrogen can cause overstimulation of growth of aquatic plants and algae. Excessive growth of these organisms, in turn, can clog water intakes, use up dissolved oxygen as they decompose, and block light to deeper waters.
How does phosphorus affect algae growth?
Too much phosphorus can cause increased growth of algae and large aquatic plants, which can result in decreased levels of dissolved oxygen– a process called eutrophication. High levels of phosphorus can also lead to algae blooms that produce algal toxins which can be harmful to human and animal health.
What are the effects of nitrates and phosphates in aquatic ecosystems?
However, at night, dissolved oxygen may decrease to very low levels as a result of large numbers of oxygen consuming bacteria feeding on dead or decaying algae and other plants. Eutrophication – “The process by which a body of water acquires a high concentration of nutrients, especially phosphates and nitrates.
Why do nitrogen and phosphorus promote algae growth?
Nutrients promote and support the growth of algae and Cyanobacteria. The eutrophication (nutrient enrichment) of waterways is considered as a major factor. The main nutrients contributing to eutrophication are phosphorus and nitrogen. ... This phenomenon encourages the growth of algae.
Why is too much nitrogen and phosphorus bad for the environment?
Nutrient pollution is one of America's most widespread, costly and challenging environmental problems, and is caused by excess nitrogen and phosphorus in the air and water. Too much nitrogen and phosphorus in the water causes algae to grow faster than ecosystems can handle.
Hope this helps :)
Increased nitrogen and phosphorus in water systems can lead to eutrophication, a process where excess nutrients overstimulate the growth of microorganisms. The consequent death and decay of these organisms deplete oxygen levels in the water, negatively impacting the survival of other aquatic life and creating 'dead zones'. Careful use and regulation of fertilizers can help mitigate these issues.
Explanation:Increased nitrogen and phosphorus in water systems, often resulting from fertilizer runoff and sewage, can cause significant environmental changes and consequences. These nutrients stimulate the excessive growth of microorganisms, such as algae, which can lead to an effect known as eutrophication.
Eutrophication is a process where the overabundance of nutrients leads to rapid growth of plants and algae. When these organisms die, their decomposition by bacteria depletes the water's oxygen, creating conditions that are harmful to other aquatic life. This can cause large scale mortality of fish and other aquatic organisms, creating 'dead zones' in the affected body of water.
Fertilizers are crucial in agriculture and residential settings, but their misuse or overuse can have serious impacts on aquatic ecosystems. Therefore, it is essential to advocate for responsible use and regulation of fertilizers, and to consider solutions like the restoration of wetlands, which can absorb excess nutrients.

how does a closet Lake differ from an open Lake
An open lake is a lake where water constantly flows out under almost all climatic circumstances.
In a closed lake , no water flows out, and water which is not evaporated will remain in a closed lake.
Answer:
A closed lake has "no outlet stream". This is how the closet Lake differ from an open Lake.
Explanation:
Open lakes, as the name says, are open to other water bodies. This allows the lake to drain the water in it into the other, generally the larger water body that it is connected to. On the other hand, closed lakes are literally closed and are not connected to any other water body. The water from these lakes has no other way out other than evaporation.the term that describes the size and shape of the land features on Earth's surface

What happens to atmospheric pressure as a person rises in altitude?
Answer:
Atmospheric pressure decreases with the increase in altitude.
Hope This Helps! Have A Nice Day!!
Answer:
Atmospheric pressure decreases as a person rises in altitude.
Explanation:
The pressure is the ratio of the weight of the air to unit area. So, as the height increases, the pressure decreases. That is, the pressure is inversely proportional to the altitude. At such higher levels, the air molecules are very less than at lower levels. Humans can survive up to 20,000 feet that are 3.8 miles above sea level. This is due to the decrease in the oxygen rate called hypoxia, which means oxygen deprivation.

Final answer:
The major reason that a republic replaced the old system of government in China in 1911 was ruthless rule by the powerful emperor.
Explanation:
The major reason that a republic replaced the old system of government in China in 1911 was ruthless rule by the powerful emperor. The Qing Dynasty, which had ruled China for over two thousand years, was weakened and corrupt. The emperor's rule was seen as oppressive and not in the best interest of the Chinese people. As a result, a revolution led by Dr. Sun Yat-sen and his Xinhai Revolution overthrew the empire and established a republic.
Which material most likely would form an aquiclude
A.Gravel
B.Sandstone
C.clay
D.sand
Answer:
C. Clay
Explanation:
Answer:
Clay is more likely to form an aquiclude.
Explanation:
The zone that acts as a resistance to the flow of ground water from an aquifer to the other aquifer is called as the aquitard. Aquiclude or aquifuge is a wholly impermeable aquitard that permits no ground water from between the aquifers.
In general, while the highly fractured rocks, gravel and sandy materials makes good aquifer, the clay, poorly settled sediments, and non-fractured rocks often forms aquitard.

This same man gave theories to about the fossils and rock formations of the drifted continents that were once together.
How can scientist locate the epicenter of an earthquake
Scientist use triangulation method to locate the epicentre of an earthquake from the data collected from Seismograph.
Explanation:
The seismic data from three different location is collected to locate the intersect point as the epicentre point to be determined. Each earthquake is recorded in seismogram in different location.
A seismogram is the output from a graph called seismograph, which is used to determine the epicentre of an earthquake. There are two waves namely P-waves or Primary waves and S-waves or secondary waves that are considered while finding the epicentre of an earthquake.
With the seismogram, P-waves appears first before S-waves, since they travel faster through three states of matter. Thus, data from seismograph is used for locating “epicentre of an earthquake”.
Answer:
-Record of waves from at least 3 seismograms are used to locate earthquakes.
-Difference inn arrival times of P and S waves give distance from seismometer to earthquake

if the viscosity of a magma is high, the magma is more likely to
a)make dark colored rocks.
b) contain trapped gasses.
c) contain relatively small amounts of silica.
d) lead to a non-explosive eruptions.
Answer:
b) contain trapped gasses
Explanation:
The highly viscous magma is a magma that has high content of silica, and high content of gasses. There's two types of magma that have these characteristics, intermediate (andesitic) and felsic (rhyolitic). The high content of silica makes the magma highly viscous, and that composition actually traps the gasses inside the magma. As the magma rises toward the surface, the pressure and temperature change, resulting in explosion of the trapped gasses, thus creating explosive and effusive eruptions. Through this eruptions, the volcanoes shot out lot of pyroclastic material, making their surroundings very dangerous.

which of the following processes has directly caused ocean currents to change over earths history
A. axial precession
B. continental drift
C. ice-albedo feedback
D. volcanic activity
The answer is b. Continental drift
Answer:
Continental drift has directly changed ocean currents over earth’s history.
Explanation:
Plate tectonics is the process by which the continents drift about the planet Earth. This drifting will be usually two to three centimetres a year. When this happens over a million years, there will be significant change in size and position of land areas. This can explain about the climate changes on our planet. In earlier days of Earth history, the continental plates were locked together without moving. This changes gradually increased over time, expansion of land masses has affected the ocean currents. This will in turn affect the climate as the ocean currents involves the transfer of heat across the area.What are three ways in which tradition is part of everyday life in south Asia
Answer:
The Indian subcontinent forms an inverted triangle extending from the snow-bound Himalayan ranges of Asia toward the equator. Known also as South Asia, the area includes the countries of India, Pakistan, Bangladesh, Sri Lanka, Nepal, and Bhutan; artistically, the Tibetan highlands also form part of the region. Stretching some 1,800 miles from north to south, and almost the same distance from west to east, the area is home to an ancient and diverse group of cultures.
India is the largest single nation of South Asia. Its currently twenty-four states exhibit a cultural diversity comparable to that seen among the nations of Europe. The Tamil region of South India has a language, script, musical tradition, dance forms, and an artistic heritage that are quite distinct from those found in, say, Punjab in the north. It is this diversity that makes the artistic traditions of India so complex and rewarding to follow.
During the third millennium B.C., spacious cities, displaying advanced town planning, were built along the plains of the Indus River. The settlers of these ancient communities traded with the contemporary civilizations of Mesopotamia and used an elegant form of pictorial writing that is yet to be deciphered. Steatite seals, delicately carved with figures of animals and occasionally of humans, testify to their creators’ artistic sensibilities. The great cities of the Indus Valley flourished for more than a thousand years.
Explanation:
Tradition in South Asia is evident in cultural and religious festivals, traditional economy and occupations, and social customs and practices, which are central to the region's way of life.
Tradition plays a significant role in everyday life in South Asia through various aspects of society. Here are three ways tradition is woven into the daily life of South Asians:
These traditions resonate through the region's socio-economic dynamics, cultural festivals, and daily social customs, shaping the unique identities of communities within South Asia.

How many cubes with side lengths of 1/3 cm does it take to fill the prism?
Answer:
we need 48 cubes to fill the prism
Explanation:
To know how many cubes does it take to fill the prism we are going to do the following:
1. Calculate the volume of the prism:
Volume = Width x Lenght x Height
Volume = 1cm x 2 2/3 xm x 2/3 cm = 16/9 cm^3
2. Calculate the volume of the cube:
Volume cube = (1/3 cm)^3 = 1/27 cm^3
3. Now Number Cubes = Volume prism / volume cube
Volume prism / volume cube = (16/9) / (1/27) = 48
Then we need 48 cubes to fill the prism.
What is the specific type of plate boundary for Papua New Guinea? (transform, divergent, convergent?)
Answer: Convergent plate boundary
Explanation: Convergent plate boundary is a location on earth where two tectonic plates are moving towards each other and the denser plate slides beneath the less dense plate (this process is known as subduction). The collision of these plates results in earthquakes, volcanoes, and formation of mountains.
There are three types of convergent plate boundary
1. Oceanic- Continental Convergence
2. Continental- Continental Convergence
3. Oceanic- Oceanic Convergence
In the case, of Papua New Guinea, it was formed by the collision of the very large northward moving Indo-Australian tectonic plate with the even large westward moving Pacific plate.
