What are deserts?

Deserts are fascinating places with unique landscapes and extreme weather conditions. Let's learn about hot and cold deserts!

Deserts

Hot deserts are hot and dry. They receive very little rainfall throughout the year. The ground is often covered in sand dunes, shaped by the constant movement of the wind. Cacti, with their sharp spines, are well-adapted to the desert's harsh conditions. These hot deserts can be found in regions like the Sahara in Africa and the Arabian Desert in the Middle East.

Hot Deserts

Cold deserts, on the other hand, have a different set of challenges. They are known for their freezing temperatures. Snow and ice cover the ground, . Cold deserts can be found in regions like Antarctica and parts of Central Asia.
