Question

it is recharged and discharged
surface water that trickles down into the ground can reach the water table and enter an aquifer. this process is called recharge, and occurs in an area called the recharge zone.
where the water table meets the surface, water may pool to form a wetland or may flow out as a spring. the process by which groundwater becomes surface water is called discharge and happens in discharge zones. discharge can feed rivers, streams, and lakes. groundwater is also discharged where water is extracted from wells that are drilled down into the water table. through discharge and recharge, the same water circulates between surface water and groundwater.
visualize it!
12 label on the illustration below, write a caption for discharge zone and for aquifer.
water enters an aquifer in recharge zones.
think outside the book inquiry
13 debate during times of little or no rainfall, many communities have regulations limiting water use. imagine that you live in a community with a depleted aquifer. as a class, develop a set of regulations that you think residents should follow. start by brainstorming as many uses of water as you can. then decide which uses should be regulated and to what extent.

Explanation:

For the discharge - zone caption, we know from the text that it is the area where groundwater becomes surface water. For the aquifer caption, the text states it is where water enters from recharge zones.

Answer:

Discharge zone caption: Area where groundwater emerges as surface water.
Aquifer caption: Underground layer where water accumulates from recharge zones.
