A desert is an area where it scarcely rains. Some are big areas of sand or flat, stony ground, while others have rocky hills and mountains. During the day, the desert’s temperature can be waxing hot, while at the night, it can be freezing cold. They also have strong winds and little rainfall, where only a few animals and plants can survive. Do you want to know how this type of environment works and what’s inside? Read about these 50 adventurous desert facts and learn how to survive if you ever find yourself stranded!

- Roughly 33% of the land surface on Earth is arid or semi-arid.
- Several polar regions also have little precipitation or much known as polar deserts or “cold deserts.”
- Deserts are made by weathering processes as large disparities in temperature between day and night put strains on the rocks.
- The biggest desert in the world is the Antarctic desert. It occupies the continent of Antarctica with a size of around 5.5 million square miles.
- Even though rain is rarely seen in deserts, rainstorms can sometimes occur followed by a deluge.
