Explain the similarity between aquifers and banks.

Both store water.

Explanation:

Aquifer is a geological formation that contains water and allows significant amounts of that water to move around in natural conditions. Permeable formations, such as sandstones and sands, are examples of aquifers.

Water banks, in turn, are excellent reservoirs for storing water in large volumes. They can be of the buried, semi-buried and supported type, which are usually in circular or rectangular shapes.

In short, aquifers and water banks store water, this is the characteristic they have in common.

Both hold bodies of water above and underground.
