Not all deserts are covered with sand. Only about 20% of the world’s deserts have sand. Have you heard about ice deserts?
When we hear the word “desert,” we usually imagine a vast sea of sand. However, this perception is not entirely accurate. Only about 20% of the world’s deserts are covered with sand. The remaining 80% consist of ice, rocks, salt, and pebbles. Among these, ice deserts are particularly fascinating, even though it might sound surprising.
What is an Ice Desert/Polar Desert?
An ice desert is a type of cold desert where most of the area is covered with ice. These deserts are typically found in the polar regions of the Earth, such as Antarctica and the Arctic. In these deserts, winter temperatures can drop below -40 degrees Celsius, and even in summer, the ice cover remains largely intact.
How Are They Formed?
Ice deserts are primarily formed due to the low temperatures in the polar regions. There is very little precipitation, and although the area is covered with ice, it is technically dry. Instead of rain, water supply comes from melting glaciers, which is the only source of water in these deserts.
Antarctica: The Largest Ice Desert
Antarctica is the largest ice desert on Earth. It spans approximately 14 million square kilometers and is one of the driest places on our planet. It receives only about 5 centimeters of snowfall per year, which is even less than the Sahara.
Biodiversity in Ice Deserts
Biodiversity in ice deserts like Antarctica is very limited. However, some unique animals live here, such as penguins, seals, and some small Arctic fish. Additionally, marine life is diverse because the sea beneath the ice provides a safe haven for many creatures.
Why Are Ice Deserts Important?
Ice deserts play a crucial role in maintaining the Earth’s climate balance. The ice in Antarctica and the Arctic reflects sunlight, which helps prevent the Earth from overheating. Moreover, if the ice in these regions melts, it could raise sea levels, causing catastrophic effects for low-lying areas around the world.
Ice Deserts and Science
Scientists conduct research in Antarctica and the Arctic to gather information about the Earth’s ancient history and future climate changes. The ice layers hold a wealth of information, making these regions a treasure trove for scientists.
Conclusion
Ice deserts are not just a marvel of nature but are also vital for the Earth’s climate and environment. They are more mysterious and a source of knowledge compared to sandy deserts. So, next time you hear the word “desert,” remember—not all deserts are sandy; some are icy too!
