When you think of a desert do you think of a dry place covered in sand?
Well if you do, you’re right.
But, unbelievably there are cold deserts too that are covered in ice!
That sounds pretty weird but true.
What is a Desert?
A desert is a place on Earth that gets less than ten inches of rain per year. They are dehydrated and can be either very hot or very cold. Hot deserts are warm during the day and very cold at night.
A desert doesn’t get a lot of rain.
Now let’s compare that to somewhere else, to see how little rainfall that is.
There is a mountain area in Hawaii, which is kind of like a funnel.
Here they get up to 11,500mm per year. That’s nearly 30 times more rainfall than a desert.
That’s quite something. No wonder deserts are so dry!
Around one-third of the Earth’s surface is covered with deserts. You will find deserts in Central Australia, South America, North and south Africa, and North America
Can you guess what the word ‘desert’ means?
Well, it means ‘abandoned place,’ which is spot on for these places that have seriously harsh conditions.
Unbelievably there are areas in the Arctic and Antarctica that have no ice, and they’re called polar deserts.
Seems amazing that those cold places have areas with no ice.
Only 20% of the deserts on Earth are covered in sand! Let’s rethink our thoughts about what deserts really are with that fact!
There are cold deserts, and these are the areas that are covered in ice or snow. Of course, hot deserts are the ones in warmer areas.

The Gobi Desert
Unfortunately, the Gobi Desert in the north of China and the south of Mongolia is growing seriously fast.
This is because of something called desertification.
Desertification is where fertile lands, where crops can grow, are turned into desert areas.
This is caused by humans cutting down forests, droughts, climate change, and other environmental causes.
The Atacama Desert in South America is the driest place in the world.
It gets less than 1cm of rain every 5 to 20 years.
Not sure that this is the place to go on holiday or go and live!
Surviving in the Hot Desert
So we always think that hot deserts are well hot, right?
Well, they are during the day, but when the sun goes down that all changes.
It can be seriously freezing in a desert at night.
The temperature on average in deserts can be 38°C during the day in some deserts and go down to -4°C at night. Of course, this varies depending on the location of the desert.
Life in the Desert
Even though deserts have severe weather, there are a few creatures and plants who like to call this home.
You get a number of shrubs and cacti, and you’ll also find animals such as lizards, rattlesnakes and coyote.
Most of the animals that live in the desert only come out at night, meaning they’re nocturnal, as it’s just way too hot to go out there during the day.
List of Desert Animals
* The list above is only a small example of the types of animals living in the desert. Can you name some others?
Sometimes, you might see a bit of water in the desert, as shallow, salty lakes sometimes develop, but they’re only there for a short time.
Have you heard about solar energy, where we use the sun to create energy; well deserts are perfect for getting all that solar energy going.
Deserts can be perfect to farm solar energy.
Did you know that over 1 billion people live is deserts! Wow, they’re brave, as food is difficult to grow and there’s hardly any water, but they adjust to their surroundings.
Desert plants like cacti have padded leaves that store water during a drought. Clever plants.
But there’s more, they’ve got those nice, sharp spines to make sure the animals don’t eat them.
Desert Dust Storms
Be careful of a dust storm!
If the wind decides to pick up some speed, it picks up dust from the surface.
These dust storms can be up to nearly 2m high and can travel hundreds of kilometres.
Some are also called Haboob, and these can be massive as you can see in the photo below
As it’s so hot, some animals have also found ways to survive in the desert.
The camel is pretty smart too.
As body fat keeps heat locked in, the animals normally store all their body fat in one area and the camel keeps it all nicely protected in its hump.
Things to do in the desert
If you think a desert would be boring, it can actually be some serious fun;
- You can go rock climbing
- Dirt biking
- Riding on camels
Just remember to keep loads of water with you.
