The Biggest Desert in the World Is Also the Coldest

Do you know that the biggest desert in the world is not the Sahara Desert? It is the Antarctic Desert, and its total area spreads 5.5 million square miles.

Deserts are a large, very dry part of land that receives little to no rainfall. Most of the time, desert regions do not have any rainfall for 12-18 months straight.

The arid lands have less than 200 millimeters of yearly rainfall. Thus, out of 365 days in a year, there is only an average of 15-20 days of rainfall.

Some places even go without rainfall for years. While some semi parched areas get a little more rainfall, around 500 millimeters yearly.

The climate is extremely dry and cannot support any vegetation. This is because the environment can only support scattered plants.

According to some researchers, any location that is entirely free of vegetation is a desert. Moreover, it also includes extremely cold locations like the Antarctic.

Facts about the biggest desert in the world

Do you know, Colchones in Chile did not have any rainfall for 45 years? Well, here are some more fun facts to know about the largest cold desert in the world:

Area covered

The desert covers an area of 5.5 million square miles or (13.8 million square kilometers), making it the biggest desert in the world. Moreover, it is bigger than the Sahara Desert, Kalahari Desert, Gobi Desert, and the Arabian Desert combined.

Rainfall

This desert gets less than 250 millimeters of precipitation each year. Some places even get less than 50 millimeters. Moreover, there is a place known as dry valleys, which has not had any rainfall for two million years.

Made up of

Almost 98 percent of the area is ice and the average thickness is from 1.5 to 4 kilometers. Less than 2 percent of the land is without ice. That is also on the coastal side.

The area is made up of big rocks, gravel plains, and rock layers. The dry valley has a frozen lake known as Don Juan Pond. Moreover, it is the world’s largest pond and the saltiest water body too. The saline level is more than 45%.

Temperature and life

The average temperature is from minus 30 degrees Celsius to minus 70 degrees Celsius in winter. But in summer, it is around minus 30 degrees Celsius.

The dry valley has the harshest weather condition and many rocky lands, making it unsuitable for any living being. Moreover, some scientists call it “a valley of death” for this reason.

Around 350 different species have been found in the Antarctic Desert, and only 5 percent of the land has plants.

About 60 to 90 percent of freshwater is present in the Antarctic Desert, which means this desert has the most fresh water in the world.

Some water bodies are so deep and salty that they do not freeze, even if the temperature is minus 20 degrees Celsius.

This biggest desert in the world used to have a warm temperature. Researchers said 40 to 50 million years ago, Antarctica as an average temperature of 15 degrees Celsius to 17 degrees Celsius.

Only two kinds of plants are found in Antarctica; Deschampsia Antarctica or Antarctic hair grass and Colobanthus quitensis or Antarctic pearlwort. They are only located on the western Antarctic Peninsula.

They even found fossils that prove that the land used to be covered with green plants and dinosaurs lived there.

People of Antarctica

Antarctica is controlled by an administration known as the Antarctic Treaty since no human being can live there.

Researchers stated the sea level would increase by 5 meters if the western ice sheet melts.

30 countries work in research stations located on the continent. It is said there are about 75 to 80 research stations.

There are about 4,000 people in these research stations during the summer months, and in winter, about 1,000.

Mountain range

Mount Erebus is the most active volcano in the world and it is located in the southern part of the continent. Moreover, it is recognized as “lava lakes” as it held molten magma in such cold weather conditions.

Red water in the Antarctic

In the early 1900s, scientists discover red water flowing in a glacier located on the east side of the continent. The water coming out from the Taylor Glacier was deep red, making the white lilies turn red.

For decades scientists did not know why this is happening. Finally, in 2017 they found out the reason. The water bodies are extremely salty and also have oxidized iron. Thus, when the water comes in contact with oxygen, they turn into rust, which results in the color.

Sunlight

During winter, there is not sunlight throughout the day, whereas in summer, it is the opposite.

The biggest desert in the world receives no sunlight in winters because the rays do not reach from the vernal equinox to the autumnal equinox due to the slanting position of the earth.
