Earth's Deserts

In June 2013, the news was published on Al Arabiya. According to the news the bodies of a Qatari man and a woman were found in the desert called Empty quarter of Saudi Arabia. The men and women were residents of Qatar. The couple came to their property in the desert, which is more than 50 degrees Celsius and spread over an area of ​​one thousand kilometers. The two were trapped in the desert when the vehicle overturned. Security forces found the woman's body near the vehicle. The husband, who had traveled ten kilometers in the scorching sun and hot sand in search of water or help, could not reach his wife and was killed by the murderous desert. The desert regions of the earth are among the most dangerous regions of the earth.

A desert is a part of the earth where there is no rain or no rain at all. Areas that receive less than 10 inches of rain a year are also considered deserts. Areas are also considered to be deserts where the water evaporates more than the rains due to high temperatures. Such areas are found near the equator. Due to the dry and hot weather, the grass and plants in these desert areas are almost non-existent. About 1/3 of the dry land consists of deserts.

All the deserts of the earth are divided into four different types.

1. Polar deserts

These deserts are located in the polar regions of the earth.

• The largest of these deserts is the Antarctic Desert. Ninety percent of the world's ice is here. Despite being a desert, the temperature here is always below zero.

The Arctic Desert is the second largest polar desert. It covers an area of ​​4.4 million square miles. The desert stretches across Finland, Russia, Norway, Iceland, Greenland, Canada, Sweden, and Alaska. This is also an icy desert. Areas that come in also have negative temperatures during most months of the year.

2. Subtropical deserts

These deserts are found around the Earth's equator. These are the driest and hottest deserts on earth. These deserts have some of the warmest regions on Earth.

• The Sahara Desert covers an area of ​​3.5 million square miles. This desert is located in the continent of North Africa. The Sahara Desert covers the North African countries of Egypt, Sudan, Chad, Libya, Algeria, Niger, Mali, Mauritania, and Morocco.

Ian The Arabian desert is the second largest sub-tropical desert. It covers Saudi Arabia, Yemen, Kuwait, Jordan, Qatar, and Iraq.

Great Australia's Great Victoria Desert is the third most subtropical desert. Which is spread over 250,000 square miles. This red rock and the sand desert is found in Western Australia.

• The fourth tropical sub-tropical is the Kalahari desert of South Africa. It covers an area of ​​220,000 square miles. In addition, eight more deserts are found in subtropical deserts. These include the deserts of Mexico, the United States, Iran, Syria, and Australia.

The Thar Desert is also one of the subtropical deserts. Part of it is in Pakistan and the rest is in India. It is the 17th largest and ninth hottest desert in the world.

3. Cold Winter deserts

• The largest of these is the famous Gobi Desert in China and Mongolia. It covers an area of ​​500,000 square miles.

The second largest of the Cold Winter Deserts is the Patagonian Desert with an area of ​​260,000 square miles. Located in the South American country of Argentina. Other cold winter deserts include the Great Basin Desert of the United States, the Kara-Kum Desert of Uzbekistan and Turkmenistan, and the Taklamakan Desert of China.

4. Coastal deserts

The deserts along the coast are called Cool Coastal. These deserts have fog in the form of moisture from the sea, but it does not rain here due to the lack of the desired environment for rain.

• The Atacama Desert of the South American countries of Chilli and Peru is one of the Cool Coastal Deserts. Spread over 44,000 square miles, this desert is located on the shores of the Pacific Ocean. Here in this desert, you can see many beautiful views at night, including the Milky Way galaxy. This place is one of the unique places in the world where the astronomical views are very clear.

• Coastal deserts include the Namib Desert of Africa and Namibia. The desert covers an area of ​​13,000 square miles.

The Sahara is the largest desert in the world. This is 2020, an estimate that 15,000 years later, in 17,000, the Sahara will turn into a lush, lush green land. Some parts of the earth that are still green will then turn into deserts. Evidence suggests that climatic intensities fluctuate in different parts of the earth (as a result of changes in winds and rainfall).

Deserts are the most difficult regions of the earth in terms of living. Life is hard in them, but still one billion people and many billions of other creatures live in these deserts. To date, no rain has been recorded in the Atacama Desert of Chile. But there are more than a million people living there. There are also some species of animals and insects that will not be found in any other part of the world except the deserts.

The surface area of ​​the whole earth is 51 crore, which is 510072000 square kilometers. Out of which, 149.94 million 148940000 square kilometers area is dry. About one-third of these 149.4 million square kilometers are deserted, and 20 percent of all these deserts are covered by sand. Therefore, if the earth is seen from space, the yellow or yellow color of these deserts is also clearly visible in the prominent colors of the earth.

These hot and treeless areas are prone to strong winds throughout the year. These strong winds blow away the dry soil and the sand layer of the earth becomes visible from below. Deserts have their own beauty and they definitely don't like to share this beauty with any other region of the earth.
