What do aquifers contain?

1. Surface water

2. Atmospheric moisture

3. Groundwater

4. Rainwater

The correct answer is: Groundwater

Aquifers are geological formations that are capable of storing and transmitting water, which is primarily groundwater. Groundwater is the water that fills the spaces between rocks and sediment underground, making aquifers an important source of drinking water and irrigation for agricultural purposes. This groundwater is replenished through processes such as rainfall and surface water infiltration, but the primary content of aquifers themselves is indeed groundwater. The configuration and characteristics of aquifers can vary, affecting how much water they can hold and how quickly it can move through them. Understanding this is crucial for effective water management and conservation practices.
