Answer 2

Humans use both surface water from rivers and lakes and groundwater from wells to supply their basic needs.

Step-by-step explanation:

Humans use both surface water from rivers and lakes and groundwater from wells to supply their basic needs. Surface water refers to water from sources such as rivers, lakes, and reservoirs. Groundwater, on the other hand, is water that is stored beneath the Earth's surface in aquifers. Groundwater is accessed through wells and is a particularly important resource in arid climates where surface water may be scarce.
