Question

How is an oasis source of water??

Answer 1

Oasis is form in desert when there is underground river or water sourcebeneath the surface, the water gets accumulated below the sand because of rocks beneath which water can't percolate. So it becomes naturally fertile for plants

Answer 2

Answer:

An oasis is a fertile area created by a freshwater supply in an otherwise dry and arid area.

Explanation:

Multiple oases are watered by subsurface water sources such as natural springs. Their sizes range from a group of date palms surrounding a spring or well to a city and its irrigated farmland. Common crops grown in oases include dates, cotton, olives, figs, citrus fruits, wheat, and corn (maize).

Most oases receive their water from underground sources known as aquifers. In some instances, an underground body of water is brought to the surface by a natural spring. Aquifers are tapped at other oases by artificial wells. These wells may be centuries old and have maybe been meticulously maintained for generations in certain oasis towns to keep access to their life-giving water.

The Sahara Desert has roughly 90 major oases supported by some of the world's largest subterranean water reserves.

The Sahara, which is about the size of the continental United States, is the largest desert on Earth. Although there are many oases there, due of how large the desert is, navigating between them can take days.

Oases have developed into significant stopping points on trade routes because of this, both in the Sahara and elsewhere in the world. Along these routes, traders and merchants are required to refuel at oases with food and water.
