Question

areas where water can soak down through the soil and permeable rock to join a groundwater supply. runoff layer. recharge area. confined surface. discharge area.

Explanation:

A recharge area is a region where water infiltrates the soil and permeable rock, replenishing the groundwater supply. Runoff layer is not a standard term in this context. A confined surface refers to an aquifer trapped between impermeable layers. A discharge area is where groundwater emerges, not where it soaks in.

Answer:
