An oasis can be formed by an underground aquifer or river that creates enough pressure for water to seep to the surface, forming the oasis. These aquifers and natural springs allow for life to exist in harsh climates like the desert and are often well known to local herders, farmers, and travelers in the region.

How are depressions and oasis formed?
In deserts, depressions are formed when the sand is carried away by the winds. When underground water reaches the surface of the depressions, an oasis is formed.

Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods.

In others the water can be very pure. ... If the water is not heavily mineralised and good quality then you can boil the water an drink it.
Why there is no rain in desert?
Hot, moist air rises into the atmosphere near the Equator. As the air rises, it cools and drops its moisture as heavy tropical rains. ... The descending air hinders the formation of clouds, so very little rain falls on the land below. The world's largest hot desert, the Sahara, is a subtropical desert in northern Africa.
Why do deserts have sand?
This sand was washed in by rivers or streams in distant, less arid times – often before the area became a desert. Once a region becomes arid, there's no vegetation or water to hold the soil down. Then the wind takes over and blows away the finer particles of clay and dried organic matter. What's left is desert sand.
Why is Antarctica a desert?
Antarctica is a desert. It does not rain or snow a lot there. When it snows, the snow does not melt and builds up over many years to make large, thick sheets of ice, called ice sheets. Antarctica is made up of lots of ice in the form of glaciers, ice shelves and icebergs.
