Question

question #2 how do fluctuations (changes) in rainfall and human water usage affect the level of water in aquifers? what are the consequences of depleted aquifers?

Explanation:

Rainfall is a key source of water recharge for aquifers. More rainfall generally leads to higher water levels, while less rainfall can deplete them. Human water usage, such as excessive pumping, also lowers aquifer levels. Depleted aquifers can cause land - subsidence, reduced water availability for domestic and agricultural use, and saltwater intrusion in coastal areas.

Answer:

Fluctuations in rainfall and human water usage can either recharge or deplete aquifers. Higher rainfall can increase water levels, while excessive human usage can lower them. Consequences of depleted aquifers include land - subsidence, reduced water supply, and saltwater intrusion.
