Deserts In The World And Their Formation
Deserts in the world and their formation is the article in which you will get the knowledge of world famous deserts, their location and how the deserts formed. We have a large number of deserts in the world which are small and big all over the world. The Sahara desert occupied larger part of North Africa. The world smallest desert in the world is the Carcross Desert which is located in Canada, North America. It is also one of the famous tourist place in Canada.
One third of the land on the globe is covered with deserts. Deserts receive rainfall in a very small amount that is bellow 25 cm in a year. We can see the deserts of stony, sandy etc., but all deserts are dry places. Desserts are very cold at night and very hot during day time.
People, plants and animals have adapted to this environment and live in these places.
In this environment only some animals and plants inhabit and survive to this extreme temperature changes.
On the tropic of Cancer and Capricorn deserts are formed
To the north of the equator by 23.5° the Tropic of Cancer is situated and to the south of equator by 23.5° the Tropic of Capricorn is situated. The areas situated at those above points the greatest deserts are formed. We can take the examples of the Great Sahara desert and the Great Sandy Desert. The second largest desert, Gobi desert is located in the middle of large continents where the rainfall is often.
Reasons for the formation of Deserts
1. Equatorial wind belts
The raising of warm air at equator causes the wind belts which flow to the north and south of equator which ultimately forms the desert in world. Due to the dryness of air at the tropics of cancer and Capricorn clouds are not formed. Since lack of rainfall, deserts are formed.
2. Rain shadow
It also results in Deserts. When the air passes by high mountain ranges, the moisture content in air reduces thus the land receives less rainfall which are beyond mountain ranges. Example is the Gobi Desert.
3. Cold Currents
The sweeping of cold currents upwelling from the ocean floor in the southwestern coasts of Africa and South America by the air makes the air that passes over these currents will get cold. Causing the water in the air to fall as rain before it reaches the land. The Namib and Atacama deserts are examples of this phenomenon to form deserts.
Water in Deserts
Even though water is a very rare thing in deserts it has been affected by the way they look. Drowning is one of the desert hazards!
Flash flood is the phenomenon of flooding of wadis which is the dry river bed.
When it rains the water won’t be going under the ground or be trapped by the plants on ground since the ground is too hard to flow.
Even though floods may occur several years apart they make a big difference in influencing the landscape of desert like salt pan, alluvial fans, mesas and butte.
A layer of salt crystals is formed on the ground when a salt pan or playa which is a lake of salty water dries out.
Due to flood of water, Alluvial fans are deposited substances on the. The hard rock landforms which are not taken away by flood are Mesas and butte.
Deserts In Different Continents And Their Formation
Wind action in deserts
In deserts, wind acts in 3 different ways. It makes the land erode, transport and deposit somewhere else.
when sand is taken away by the wind it gets transported. Sometimes rock surfaces may hit by sand. Over the millions of year’s time, the weaker parts of rock may break and beautiful shapes may form.
Desert depressions are formed due to wind. They are caused by the deflation process which occurs when the smallest particles of the sand are transported by wind and the rest is left.
Deposition is the process of transportation of sand by wind to somewhere.
Loess is a end product of this process. This is a deposit of very fine material. on the edge of the arid areas in Asia and Europe these fine material is found.
The wind also causes the sand dunes. The particles of sand are deposited and piled into heaps which gradually increase in size. The wind direction decides the shape of dune.
Living in a desert is a difficult and audacious thing. It gives little to eat and inadequate water. Even though, some animals adapted to the environment of desert to inhabit.
Animals In Deserts
Many of the desert animals take little water and can travel for many days without even having water. The animals which live in deserts get water from plants and insects when they consume. As nights are cooler here, wild life goes for a hunt at night times.
In the day time most of them hide in burrows or stay in the shade. Usually camels are used for transport in deserts by humans. It can intake 120 litres of water at a time and can travel for several days. Horses are also used for transport, but they consume water regularly and take more rest than camels.
Plants In Deserts
Potential and very few plants are found in deserts. Mostly they have long roots to access the water from underground. These plants store water in the roots and leaves in order to survive the ever drought conditions. Some flowers sprout out suddenly when it rains but dies out when rain stops. Cactus plants are most common plants found in deserts and they have longer roots to access underground water. Cactus can also store water when it rains.
