GEOLOGY

Detailed explanation-1: -An aquifer receives 20 m3 of precipitation and loses 2 m3 of water through natural movement. If the water budget must be balanced, how much water can be pumped from the aquifer? 22 m3.

Detailed explanation-2: -The water budget of Earth as a whole is balanced because the amount of precipitation is equal to the amount of evapotranspiration and runoff. However, the water budget of a particular area, called the local water budget, usually is not balanced.

Detailed explanation-3: -An aquifer is a body of porous rock or sediment saturated with groundwater. Groundwater enters an aquifer as precipitation seeps through the soil. It can move through the aquifer and resurface through springs and wells.

Detailed explanation-4: -An aquifer is a body of rock and/or sediment that holds groundwater. Groundwater is the word used to describe precipitation that has infiltrated the soil beyond the surface and collected in empty spaces underground.

Detailed explanation-5: -Aquifers get water from precipitation (rain and snow) that filters through the unsaturated zone. Aquifers can also receive water from surface waters like lakes and rivers.
