different types of lava have different viscosities, depending on their composition or temperature, or both. label the types of lava flows based on their relative viscosities.

Answers

Answer 1

The viscosity of lava depends on a variety of factors, including its temperature, composition, and the amount of gas it contains. These factors can all affect how the lava flows and what type of structures it creates.

There are three main types of lava flows that can be classified based on their relative viscosities:

Pahoehoe Lava: This type of lava has a relatively low viscosity and is very fluid. It forms smooth, rope-like or billowy structures as it flows. Pahoehoe lava is typically hotter and less viscous than other types of lava, which allows it to flow quickly and for long distances. It is often found on shield volcanoes, such as those in Hawaii.Aa Lava: Aa lava has a higher viscosity than pahoehoe lava, making it more difficult for the lava to flow. As a result, aa lava tends to form a rough, blocky surface with sharp edges and spiny projections. It can be very difficult to walk on, and its rough surface can cause damage to buildings and other structures. Aa lava is typically found on volcanoes that are more explosive and have more viscous magma, such as those in Iceland.Blocky Lava: Blocky lava is the most viscous type of lava and forms when the lava is so thick that it cannot flow far from the vent. As the lava cools, it forms large, angular blocks that can pile up to create a lava dome. Blocky lava is typically found in areas with explosive eruptions, such as stratovolcanoes. It can also form at the end of a lava flow, where the lava cools and solidifies in place.

Which of the metamorphic agents is plays the driving role in the formation of mountains?
a. presence of fluids
b. heat
c. differential pressure
d. All contribute at the same level

Answers

Answer:

(c) differential pressure

Explanation:

While all of the listed metamorphic agents can contribute to the formation of mountains, differential pressure, which is a type of stress that can result from tectonic activity, plays the driving role in the long-term geological processes that lead to the creation of mountain ranges. This pressure can cause rocks to deform and become folded or faulted, leading to the creation of large-scale geological features such as mountain ranges. Heat and the presence of fluids can also contribute to the process of mountain formation, but they are not typically considered to be the primary driving forces behind this process. Therefore, the correct answer is (c) differential pressure.

The metamorphic agents is playing the driving role in the formation of mountains are d. All contribute at the same level.

The formation of mountains is a complex process that involves multiple metamorphic agents.

The presence of fluids can aid in the movement of minerals and facilitate chemical reactions that contribute to the formation of mountains.

Heat can also play a role in the formation of mountains by causing the deformation of rocks and the formation of new minerals.

Differential pressure, or the unequal pressure on different parts of a rock, can also contribute to the formation of mountains by causing folding and faulting of the rock.

All of these agents contribute at the same level to the formation of mountains, making option d the correct answer.

what type of unconformity separates the bright angel shale from the vishnu schist (indicated by black arrows)?

Answers

An angular unconformity separates the Bright Angel shale from the Vishnu schist (indicated by black arrows).

An unconformity is a geological feature that represents a gap in the geological record. This gap is caused by a period of erosion or non-deposition, which removes or prevents the accumulation of sedimentary rock layers.

An angular unconformity is a type of unconformity that occurs when sedimentary rock layers are deposited on top of tilted or folded rock layers.

In the case of the Bright Angel shale and Vishnu schist, the Vishnu schist was tilted or folded before the deposition of the Bright Angel shale. As a result, the two rock layers are separated by an angular unconformity, which is indicated by the black arrows in the diagram.

This unconformity represents a gap in the geological record, and provides important information about the geological history of the area.

with reference to temperature and rainfall identify and explain the differences in the climatic zones​

Answers

Answer:

Temperature and precipitation are the basic and detrimental factors when it comes to climate types.

Explanation:

There are multiple different climate types across the globe. There are numerous factors that influence their characteristics, but the most important are temperature and precipitation. The warmer and wetter it is, the more organisms thrive, and the colder or hotter and drier it is, the fewer organisms thrive.

The tropical rainforests have high amounts of precipitation and high temperatures all year round, thus they have high biodiversity. The deserts have very high temperatures (some also very low in winter) and lack of precipitation, so there is very little biodiversity.The temperate climates have medium amounts of precipitation and high variation in temperature from one to another season, leading to having moderate biodiversity.The polar climates have very low temperatures and very low precipitation, so they have the least biodiversity.

true/false. the earth is a/an open or closed system as far as energy is concerned and a/an open or closed as far as ""rocky"" material

Answers

It is FALSE that the earth is a/an open or closed system as far as energy is concerned and a/an open or closed as far as ""rocky"" material.

The Earth is an open system when it comes to energy, as it constantly receives energy from the Sun in the form of sunlight. However, it is a closed system when it comes to "rocky" material, as the total amount of rocks and minerals on Earth remains relatively constant. While rocks can undergo various processes like erosion, weathering, and volcanic activity, the overall amount of rocky material on the planet does not significantly change over time.

To elaborate, as an open system for energy, the Earth receives solar radiation that provides heat and fuels various processes such as weather patterns, ocean currents, and photosynthesis. This energy is not self-contained but is continuously exchanged with the surrounding space. On the other hand, as a closed system for rocky material, the Earth's internal processes, such as volcanic activity, can recycle rocks, but the total amount of rocky material remains relatively stable due to the conservation of mass.

Explanation:

describe the role ""friction"" plays towards creating converging surface winds around low-pressure areas.

Answers

Friction plays a significant role in creating converging surface winds around low-pressure areas. As air flows towards a low-pressure area, it encounters friction with the surface of the Earth. This friction slows down the movement of air close to the surface, causing it to pile up and accumulate in the low-pressure area. This accumulation of air creates a convergence zone, where air is forced to move upwards due to the increasing pressure. As a result, this upward movement of air creates the low-pressure system's characteristic counterclockwise rotation in the Northern Hemisphere and clockwise rotation in the Southern Hemisphere. In summary, friction helps to create converging surface winds that contribute to the formation and maintenance of low-pressure systems.
Hi! Friction plays a crucial role in creating converging surface winds around low-pressure areas. It causes the winds to slow down and change direction, allowing them to spiral inward towards the low-pressure center. This inward spiraling motion leads to the convergence of surface winds, ultimately causing the upward movement of air, which results in cloud formation and precipitation. In summary, friction contributes to the convergence and circulation of surface winds around low-pressure areas, influencing weather patterns.

the dominant geologic process in our solar system is:

Answers

The dominant geologic process in our solar system is impact cratering. Impact craters are caused by the collision of asteroids, comets, and meteoroids with the solid surface of a planet or moon.

These collisions release enormous amounts of energy that excavate a circular pit, ejecting rock fragments outward, and forming a rim of uplifted material. The number and distribution of impact craters provide important clues to the age and history of a planet or moon.

For example, a planet with many impact craters must be relatively old and have a geologically inactive surface that has not been resurfaced by other processes. In contrast, a planet with few craters must be relatively young and have an active surface that is constantly being modified by tectonic, volcanic, or erosional processes.

1. ocean water evaporates into the air
2. wind produces waves on the ocean
3. water evaporates from the ocean and goes into the air
4. rain falls on a slope and washes soil away​

Answers

The atmosphere interacts with the lithosphere occurs when water evaporates from the ocean and goes into the air. Thus, option 3 is correct.

Following the water's entry into the lower atmosphere, rising air currents lift it higher and frequently quite high into the atmosphere, where the air is cooler. Water vapor is more likely to transform from a gas to a liquid and produce cloud droplets in the chilly air.

Cloud droplets can develop into precipitation, which is the main way that water is returned from the sky to the Earth's surface. Precipitation includes rain, snow, sleet, freezing rain, and hail. The trajectories that precipitation takes after falling on the ground take a variety of paths. Some of it evaporates and returns to the atmosphere, while other parts sink into the earth and become groundwater or soil moisture, and still other parts run off into rivers and streams.
