How does a gravel desert develop?
A desert is an area that has no or little vegetation. The vegetation covers less than 5% of the surface. There are different types of desert, including the gravel desert, which is created by erosion.
Deserts are very well known areas of the world. A distinction is made between rocky deserts, gravel deserts and sandy deserts. How a gravel desert is created is briefly shown below. It is shown that the erosion of stone and rock deserts creates the gravel desert.
How a gravel desert is created
- So that a gravel desert can arise at all, the origin must be indicated.
- Both the stone and rock desert, which is needed to create a gravel desert, are to be named as the origin.
- During the day the floor warms up to approx. 80 ° Celsius. When the sun goes down, it cools down to 10 ° Celsius or it even gets colder at night.
- The rock expands during the day due to the intense heat. At night, on the other hand, the rock contracts in the cold. These enormous temperature fluctuations within a very short time create strong tensions in the rock.
- The result is that the strong stresses cause cracks to form in the stones or to break apart.
- This permanent impact creates the gravel desert.
- Once the gravel desert has arisen, the wind ensures that the fine grains of sand develop into a sandy desert.

A gravel desert continues to develop in the Sahara as well
The Sahara is known to many as an example of the desert, where the gravel desert is gradually emerging. The idea, however, is that it is made of sand. Of course, sand is part of the Sahara, but the fact is that sand is only one fifth (20%) of the Sahara. Half of the Sahara consists of gravel desert (50%). According to this, 30% is accounted for by the stone and rocky desert.
