Question

a. Influent streams discharge groundwater and are characteristic of arid regions.
b. Influent streams discharge groundwater and are characteristic of humid regions.
c. Influent streams recharge groundwater and are characteristic of arid regions.
d. Influent streams recharge groundwater and are characteristic of humid regions.

Answer 1

The statement 'influent streams recharge groundwater and are characteristic of arid regions' is true.

Option: (c)

Step-by-step explanation:

• Live reservoirs like lakes and ponds in arid regions are not a result of rains.

• These reservoirs are either formed by small streams confluencing at one common point or due to a meander leftover off a river that was once active.

• The confluencing streams are classified as influent because they 'flow in' to form a reservoir.

• They recharge such water resources by the water brought from far away places and keep the water resources in the arid region alive.
