Groundwater Flashcard T6EX2

Front

What is the Ogallala aquifer?

Back

The Ogallala aquifer is a vast underground water source in the central United States, formed by ancient rivers millions of years ago, and is crucial for agricultural irrigation.

Front

How can human actions beneficially influence the Ogallala aquifer?

Back

Implementing water conservation measures can help maintain groundwater levels in the Ogallala aquifer.

Front

What happens to groundwater when a chemical spill occurs in a river?

Back

Groundwater can be affected because river water can seep into the ground and recharge the groundwater.

Front

What is the water table?

Back

The water table is the upper surface of the zone of saturation in the ground, where the soil or rock is fully saturated with water.

Front

How has the water table changed over time?

Back

The water table can rise or drop over time due to factors like rainfall, drought, and human usage.

Front

What might cause a decrease in water levels over time?

Back

Decreased water levels can be caused by drought conditions or overuse of groundwater resources.

Front

What is groundwater recharge?

Back

Groundwater recharge is the process by which water from precipitation or rivers seeps into the ground to replenish aquifers.

Front

What is the relationship between rivers and groundwater?

Back

Rivers can influence groundwater levels; when river water seeps into the ground, it can recharge the groundwater.

Front

What are water conservation measures?

Back

Water conservation measures are practices aimed at reducing water use and preserving water resources.

Front

What is the impact of drought on groundwater levels?

Back

Drought can lead to a significant decrease in groundwater levels due to reduced recharge and increased evaporation.
