Desert

What is a desert?

The definition of a desert is a region so arid because of little rainfall or snowfall that it supports only sparse and widely spaced vegetation or no vegetation at all.

 

A desert has 4 main characteristics

1. Super-dry air

2. Little rain – less than 10 inches a year

3. High daytime temperatures

4. Lots of wind

 

 

 

A desert landform is a place that gets little to no rain. The climate can be either hot or cold and sometimes both. Each desert landform has one thing in common; it has less than 10 inches of rain per year. Usually deserts have a lot of wind because they are flat and have no vegetation to block out the wind.

Some of the most famous hot temperature deserts in the world is the Sahara Desert located in. One of the facts about the Sahara desert is it is the largest and hottest type of desert landform in the world.

Antarctica is actually a type of cold desert or polar desert. It is actually our largest cold desert landform. Some of Antarctica actually gets no snow. It is just a large area of very cold rock!

How is a Desert Landform Made?

The first thing about any desert is it needs to be on land. The second part is it gets little rain or snow throughout the year. It needs to get 10 inches or less a year. With little rain, vegetation is very little, causing dust and sand to blow around because there is nothing to hold it in place. Year without rain or snow causes a dry landform that we call a desert.

 

Desert Landform Examples:
The Sahara Desert
Great Basin Desert
