Question

1. a city increases the amount of groundwater pumped from its aquifers to support its growing population, but the water level of the aquifers drops.

which of the following is not a possible consequence of these actions?
land subsidence, or sinking of land
eutrophication, or a body of water becoming nutrient-rich which results in an increased growth of organisms
salt water migration into aquifers
lower lake and stream levels
clear all

Explanation:

• Land subsidence occurs when aquifer levels drop, as the underground sediment loses water support and compacts.
• Salt water migration into aquifers is a common result of falling groundwater levels, especially in coastal areas, where saltwater moves into the now-empty aquifer space.
• Lower lake and stream levels happen because groundwater feeds these surface waters; when aquifer levels drop, less water seeps into them.
• Eutrophication is caused by excess nutrients (like fertilizers) entering water bodies, not by declining aquifer levels from over-pumping.

Answer:

B. eutrophication, or a body of water becoming nutrient-rich which results in an increased growth of organisms
