Why Are Deserts Hot And How Are They Formed? - Science ABC

Deserts are hot because of the low specific heat capacity of sand and rock. Deserts are formed as a result of high pressure zones, continentality, coastal cooling and rain shadow areas.

Did you know that deserts occupy 20% of the Earth’s surface?

When we think of deserts, it is natural to think of heat, dryness, barren land and lifelessness, but they are much more than that, and in some ways, abundant in life.

We all know that the Sahara Desert is the largest desert in the world, but this is the largest “hot” desert, whereas Antarctica is the largest “cold” desert in the world.

Yes! Deserts aren’t only hot; they can also be cold! Deserts occur in regions that receive less than 50 cm rainfall per year, meaning that temperature isn’t part of the classification.
