How is groundwater typically found?

Groundwater is typically found in permeable rocks because these materials have the ability to allow water to flow through their pore spaces, which is essential for the storage and movement of groundwater. Permeable rocks, such as sandstone and limestone, are characterized by their interconnected voids, which act as reservoirs for water. This underground water accumulates in saturated zones below the Earth's surface, where it can be accessed through wells and springs.

Other options do not accurately describe the typical locations of groundwater. Ocean beds are primarily composed of water, thus groundwater is not located there. Although confined aquifers can contain groundwater, they are not the only environments where groundwater is found; it can also exist in unconfined aquifers or within permeable rock formations. Atmospheric clouds consist of moisture in the air, but they are not a source of groundwater, which is found beneath the surface of the Earth. This distinction highlights why the choice of permeable rocks as the correct answer emphasizes the key role of geological formations in storing and transmitting groundwater.
