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.

Explanation:
Why is there a water shortage if two-thirds of the earth is covered my water.
Answer:
Water shortages are caused by climate change, such as altered weather patterns including droughts or floods, increased pollution, and increased human demand and overuse of water. A water crisis is a situation where the available potable, unpolluted water within a region is less than that region's demand.
Explanation:
Some places may not have access to water either. For example Nigeria don't have access to drinking water or a sanitation system for the water that is their water shortage crisis. A place may have also had a river or stream that dried up, so it's not so much of the whole world has a shortage it's more of that one or more places seperate have a water shortage.

A person lives on the Equator. What is the altitude of Polaris?
30°
90°
45°
66° 33"
23 1/2°
0°
A person living on the Equator would observe Polaris (the North Star) at an altitude of 0°. The right answer is f.
The North Celestial Pole, that sits directly above the North Pole of the Earth, is not far from Polaris. Polaris, on the other hand, would be 0 degrees over the horizon when viewed from the Equator, where it will appear on the horizon.
The North Star is in line with the Earth's rotational axis and appears directly above the North Pole as a result of the Earth's axis' tilt with respect to its orbital plane. But since the Equator is so far from the North Pole, Polaris would be hardly discernible and would be at a very low altitude, making observation from this point all but impossible.
The correct answer is option f.
