Question

Many areas of the world rely on aquifers for water for household, industrial, and agricultural use. Experts predict that some of these aquifers are at risk of running dry. 4a. Which one of the following would be useful for reducing this risk? (1 point) Responses adding pavement above the aquifer to reduce groundwater seepage adding pavement above the aquifer to reduce groundwater seepage enforcing strict limits on the amount of water pumped from the aquifer enforcing strict limits on the amount of water pumped from the aquifer expanding aquifer access with more wells expanding aquifer access with more wells increasing pumping speed to remove water from aquifers quickly increasing pumping speed to remove water from aquifers quickly Question 2 4b. Label the processes associated with aquifers.(2 points) recharge subsidence pollution mining slow ___ (replenishment) rate ground collapse above depleted aquifer excessive ____ (pumping water up for use) chemicals applied to ground seeping into aquifer Skip to navigation page 1 of 1

Answer 1

4a. The most useful option for reducing the risk of aquifers running dry is enforcing strict limits on the amount of water pumped from the aquifer. This approach helps ensure that the withdrawal of water does not exceed the natural replenishment rate of the aquifer.

4b. Here are the labeled processes associated with aquifers:

1. Recharge
2. Subsidence
3. Pollution
4. Mining
5. Slow (replenishment) rate
6. Ground collapse above depleted aquifer
7. Excessive (pumping water up for use)
8. Chemicals applied to ground seeping into aquifer

Feel free to fill in the blanks with the terms "replenishment" and "pumping" as indicated!
