What role do aquifers play in the water cycle? a. they store water in the ground. b. they transfer water to the air. c. they are the main source of water on earth. d. they move water through capillarity.

The correct answer is - a. They store water in the ground.

The aquifers are geological features, located inside the ground, constructed of permeable rocks, and they are natural storage for water in the ground.

The water in the aquifers can be moving, where the aquifer will be a transition zone, or it can be static, where the aquifer will act strictly as a storage for the water.

The size of the aquifers varies in size, and that is mostly dependent on the rock composition, and on the amount of precipitation at a particular place.
