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?\n22 m³\n36 m³\n18 m³\n20 m³

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?\n22 m³\n36 m³\n18 m³\n20 m³

Answer

Explanation:

Step1: Determine net - gain of water

The aquifer gains 20 m³ from precipitation and loses 2 m³ through natural movement. The net gain of water in the aquifer is the difference between the water received and the water lost. $20 - 2$

Step2: Calculate the amount of water that can be pumped

For the water budget to be balanced, the amount of water that can be pumped is equal to the net - gain of water in the aquifer. $20- 2=18$ m³

Answer:

C. 18 m³
