a farmer is analyzing cross - sections of his land to determine where to build a well. which phrase describes the best area to dig down to the groundwater? where the saturated zone is 15 meters deep where the water table is at 100 meters deep where the unsaturated zone is 50 meters thick where there is a 25 - meter thick clay layer at the surface

a farmer is analyzing cross - sections of his land to determine where to build a well. which phrase describes the best area to dig down to the groundwater? where the saturated zone is 15 meters deep where the water table is at 100 meters deep where the unsaturated zone is 50 meters thick where there is a 25 - meter thick clay layer at the surface

Answer

Answer: where the saturated zone is 15 meters deep

Explanation:

Step1: Understand water - related zones

The saturated zone contains groundwater. A shallower saturated zone means less depth to dig to reach groundwater.

Step2: Analyze each option

The water - table at 100 meters deep means a very deep dig. A 50 - meter thick unsaturated zone means a long way to dig through non - water - filled soil. A 25 - meter thick clay layer at the surface is not directly related to reaching groundwater depth. The 15 - meter deep saturated zone is the best option for reaching groundwater with less digging.
