Final answer:
b. groundwater is stored in porous rock and aquifers. The accurate statement about groundwater is that it is stored in porous rock and aquifers.
Step-by-step explanation:
The true statement about groundwater is: "b. groundwater is stored in porous rock and aquifers". Groundwater is an essential reservoir of fresh water found in the spaces between sand, gravel, or in rock fissures. It slowly flows through these areas and can eventually emerge as part of surface water in streams and lakes.
It originates mainly from rain or snowmelt that infiltrates the ground and is a critical source for drinking water and irrigation. Some groundwater lies deep within bedrock and can remain there for very long periods of time.
The movement from areas of higher elevation to lower elevation is a natural part of its flow. Protection of groundwater resources is crucial as it is a major source of usable fresh water and is subject to contamination from various sources.
Groundwater plays a vital role as a major reservoir of fresh water and is an important source for drinking and irrigation purposes.
