Question

many scientists are concerned that the ogallala aquifer in the united states is being depleted at an alarming rate. what would most likely be a major effect of this aquifer running dry? many crops would die because irrigation water would be limited. the water cycle would come to a halt in the area. farmers would have to water crops with salt water. most people in the united states would not have drinking water.

Explanation:

The Ogallala aquifer is a major source of irrigation water for agriculture in the region. If it runs dry, the limited irrigation water would cause many crops to die as they rely on this water for growth. The water - cycle is a global process and won't halt in an area just due to an aquifer drying up. Salt water is not suitable for most crops without desalination. The aquifer is not the main source of drinking water for most people in the US.

Answer:

Many crops would die because irrigation water would be limited.
