Explanation:

The Sahara desert located in Africa is the world's largest desert by land mass. It is a dry desert found above the savannah belt of Africa.

From geologic records, the Sahara has not always been a desert throughout its history. Fossil evident found in sediments have shown that this desert used to be a lush and thriving rainforest.

In Arabic, the word Sahara means desert.

Traders use camels to cross this desert due to harsh nature of this expanse of land.
