The extinction is still happening right now and is called the holocene extinction
Answer:
This natural greenhouse effect is what keeps the Earth's climate livable. Without it, the Earth's surface would be an average of about 60 degrees Fahrenheit (33 degrees Celsius) cooler.
The unsaturated zone is the area of the subsurface that is above the groundwater table. The pores of the soil and rock in this zone contain both air and water.
<h3>What is the water table?</h3>
The water table is the subsurface border between the unsaturated and saturated zones.
The water table is an underground border that separates the soil surface from the area where groundwater saturates crevices between sediments and rock fissures.
At this point, the pressures of water and air are equal.
The unsaturated zone is the soil surface above the water table, where both oxygen and water fill the crevices between particles.
Therefore Option C is correct as it is where a person will immediately reach after drilling a well through an unsaturated zone.

The roots of trees helps hold the soil together, so it's not a
Forests do in fact, yield useful products, fruits, lumber, animals to hunt, medicine tree, so it's not b
Forests do provide a habitat for many animals, so it's not c
SO the answer must be D. For reference, soil salinization is the process in which salt content increases in the soil.
