Question

What is Groundwater Discharge?

A) The process of groundwater disappearing below the ground surface.
B) The process whereby groundwater re-appears above the ground surface.
C) The movement of groundwater within the subsurface layers.
D) The process of groundwater becoming contaminated.

Answer 1

Groundwater discharge is the process of groundwater re-appearing above the ground surface, contributing to the normal flow of rivers.

Step-by-step explanation:

Groundwater discharge refers to the process whereby groundwater re-appears above the ground surface. When groundwater flows through pores and fissures in the subsurface layers, it can eventually find its way to a stream or lake, becoming part of the surface water again. This contributes to the normal flow of rivers, as groundwater discharges into them and adds to their volume of water.
