If there were no deserts we could get many nations and countries around the world, that may have never existed.
If there were no deserts, all of the life (plants and animals) that are adapted to a desert environment would either 1) die, or 2) adapt to a different environment in order to survive.
Deserts form because of the location of mountains and because of the way air circulates around the planet.
The dry condition of deserts helps promote the formation and concentration of important minerals.
Gypsum, borates, nitrates, potassium and other salts build up in deserts when water carrying these minerals evaporates.
Minimal vegetation has also made it easier to extract important minerals from desert regions.
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life.
The lack of vegetation exposes the unprotected surface of the ground to the processes of denudation.
The four main types of desert include hot and dry deserts, semi-arid deserts, coastal deserts, and cold deserts.
Deserts are areas that receive very little precipitation.
One thing all deserts have in common is that they are arid, or dry. Most experts agree that a desert is an area of land that receives no more than 25 centimeters (10 inches) of precipitation a year.
The largest desert on earth is the Antarctic desert, covering the continent of Antarctica with a size of around 5.5 million square miles.
The Sahara is the hottest desert in the world – with one of the harshest climates.
The average annual temperature is 30°C, whilst the hottest temperature ever recorded was 58°C.
The area receives little rainfall, in fact, half of the Sahara Desert receives less than 1 inch of rain every year.
The largest desert on Earth is Antarctica, which covers 14.2 million square kilometers (5.5 million square miles).
It is also the coldest desert on Earth, even colder than the planet's other polar desert, the Arctic.
Composed of mostly ice flats, Antarctica has reached temperatures as low as -89°C (-128.2°F).
There are 23 deserts in the world.
What are the most famous deserts in the world? Some famous deserts in the world are the Sahara, Antarctic, Arctic, Gobi and Namib deserts.
