What is beneath all the sand?

Now that you understand where sand comes from, and why deserts form, you may already be able to guess what lies beneath the swirling sand. Roughly 80% of deserts aren't covered with sand, but rather show the bare earth below—the bedrock and cracking clay of a dried-out ecosystem.

Is it possible to dig a well in the desert?

When installing a water well in the desert, it's critical to make sure that it is deep enough. Typically, water wells installed in the desert must be much deeper than in areas where water is more plentiful. Work with the right water well installation contractor for help with this.

Did deserts used to be oceans?

The Sahara Desert was once underwater, in contrast to its present-day arid environment. This dramatic difference over time is recorded in the rock and fossil record of West Africa. The region was bisected by a shallow saltwater body during a time of high global sea level.

Where did all the sand in the Sahara desert come from?

The sand is primarily derived from weathering of Cretaceous sandstones in North Africa. When these sandstones were deposited in the Cretaceous, the area where they are now was a shallow sea.
