How did short term catastrophic events, such as volcanic eruptions and asteroid collisions affect the climate and biosphere?

Answers

Answer 1
Answer: Dust particles and debris from the collision float up into the Earth's atmosphere, thus blocking the sun's rays. When volcanoes erupt, they can cause chemical clouds to linger in the atmosphere, also blocking the sun's natural rays

The most easily polluted groundwater reservoirs are A. water-table aquifers.
B. sewage plant reservoirs.
C. salt reservoirs.
D. artesian wells.

Answers

The most easily polluted groundwater reservoirs are water table aquifers.

Further Explanation:

A water table explains the boundary that lies between water saturation and unsaturation ground. It is present below the rocks and soil. The water that lies after the water table is aquifers. Soil, rocks, and sediments purify it. The water table is raised through rain, snow and irrigation process. Its concentration depends on the season; it is at its higher level during the rainy season.

Sometimes, the water table crosses with a land area such as spring water and an oasis. It is exposed to the land surface from the region like canyon and cliff. The area below the pumice carries porous and light rocks that can hold more water than denser rocks. This area carries a fuller aquifer. The United States completely depends on the groundwater due to which it is more susceptible to get polluted. It occurs when the human-made substance such as oil and chemicals enters the underground water. The groundwater absorbs the fertilizer and pesticides used on crops. Therefore, it is easier to contaminate the water table aquifers.
