A high-pressure, fast-moving (>300 km/hr) mixture of pyroclastic debris including fragments and gas typically ejected vertically from a volcanic vent is called: a plinian column. ... Plate tectonics theory explains why volcanic activity occurs where it does.
A high-pressure, fast-moving mixture of pyroclastic debris including fragments and gas typically ejected skyward from a volcanic vent is called a Plinian column.
What is a volcanic vent?Magma as well as toxic eruptions emerge from openings in the Earth's crust it onto surface or into the sky. Vents might be a single, round feature, a significant, long-fissured fracture, or a little earth crack.
A plinian columns is an increased, swiftly moving (>300 km/hr), composite of volcanic lava debris incorporating pieces and gas that is often discharged upward from a volcanic vent.
The idea of plate tectonics describes why volcanic eruptions take place where it does. When some magma reaches the surface violently, an increased mixing of hot, shattered solids mixed increasing gases is thrown into the air. This mixture is known as a blast wave.

Erosion occurs on the outside curve of meanders. Why is this?
Answer:
max velocity of the stream goes towards the outside of the bend causing an erosion of the bank. (more specifically the outer bank)
Explanation:
Meanders shift their position by eroding downstream and sideways. The stream's highest velocity changes to the outside of the curve, eroding the outer bank and resulting in the sideways flow.
What occurs when a meander makes an outside bend?The river bank outside of the bend, where water flow has the maximum energy due to less friction, is eroded and undercut by the force of the stream. River cliffs will result from this. Material is deposited inside the bend where the water flow is slower and there is more friction. This will create a slope for sliding off.
A meandering stream moves laterally due to deposition on the inside and erosion of silt on the outside of the meander (which is caused by friction work) (helicoidal flow, deceleration, channel lag, point bar sequence, fining upwards).

hope it helps
Answer:
There are five processes at work in the hydrologic cycle: condensation, precipitation, infiltration, runoff, and evapotranspiration
Explanation:
The water cycle depicts the continual flow of water on Earth and in the atmosphere. It's a complex system with many separate processes. Liquid water evaporates into water vapour, condenses into clouds, and precipitates as rain and snow on the ground.
Evaporation, condensation, and precipitation are the three fundamental processes that make up the water cycle. Evaporation is the transformation of a liquid's surface to a gas.
Liquid water (from the ocean, lakes, or rivers) evaporates and turns into water vapour in the water cycle. Water vapour is a significant greenhouse gas as well. Evaporation, condensation, and precipitation are commonly taught as a simple circular cycle.
Evaporation, condensation, precipitation, interception, infiltration, percolation, transpiration, runoff, and storage are all processes that may be examined. When the physical condition of water changes from a liquid to a gaseous state, evaporation happens.
The water cycle is the course that all water takes as it passes through different phases across the Earth. Oceans, rivers, lakes, and even subterranean contain liquid water. The water cycle is the course taken by all water as it travels around our world.

pumice may float on water . give reason
Pumice floats on water because it has an incredibly low density due to the air bubbles inside of it. As it is blown out of a volcano (extrusive igneous), and dissolved gasses exsolve and more air gets into it before it hardens into pumice. The less dense air offsets the more dense rock, causing it to float.

Explain how wildlife (animals) can survive in a hot desert environment.
Some smaller desert animals burrow below the surface of the soil or sand to escape the high temperatures at the desert surface. These include many mammals, reptiles, insects and all the desert amphibians. Rodents may plug the entrances to their burrows to keep out hot, desiccating air.
Explanation:
Animals survive in deserts by living underground or resting in burrows during the heat of the day. Some animals get the moisture they need from their food, so they don’t need to drink much water.

1951-1980 average temperatures, which was 14 degrees Celsius (57.2 degrees Fahrenheit). The data show how high or low Earth's
surface temperature was above that average (14 degrees Celsius). The Global Fossils Carbon Emissions graph shows annual carbon

Natural gas emissions have no effect on global temperature increases.
D)
The burning of coal has had the greatest effect on global temperatures.
According to the information, we can state that global temperatures tend to increase as carbon emissions increase, as shown in option A.
We can arrive at this answer because:
According to the information in the question, the increase in carbon emissions is one of the main factors responsible for the increase in global temperatures.This can be proven by observing the graph, where it is possible to see that there was a significant increase in global temperatures, as carbon emissions increased.These carbon emissions are the result of the increase in human activities and industrial processes, which promote the degradation of the atmospheric layers and allow an intense increase in global temperature.

Which is evidence of universe expansion that supports the big bang theory?
A. The temperature of the universe has cooled over time.
B. The temperature of the universe has cooled and warmed repeatedly over time.
C. The temperature of the universe has warmed over time.
D. The temperature of the universe is the same as it was at the time of the Big Bang.
The Doppler red-shift of light observed from distant stars and galaxies gives evidence that the universe is expanding (moving away from a central point). This allows for Big Bang Theory, because after a “bang” occurs all of the matter moves away from the point of origin.
