Question

how can agriculture contribute to depletion of aquifers?

• pesticides can runoff into oceans.
• irrigation water often comes from groundwater.
• we wash our produce before eating it.
• animal waste runs off into surface waters.

Explanation:

Aquifers are underground layers of water-bearing permeable rock. Agriculture uses irrigation, which frequently draws from groundwater (aquifers). Over-extraction for irrigation reduces aquifer levels, causing depletion. Other options involve surface water or unrelated processes, not direct aquifer depletion.

Answer:

B. Irrigation water often comes from groundwater.
