Which continent is the driest on Earth, Check Here

Do you know that the drying mainland on the earth is Antarctic? Many people think of deserts like Sahara, but the amount of precipitation in Antarctica is less.

Some parts of it, such as McMurdo Dry Valleys, have no rain in millions of years. Even if the mainland is covered by ice, it is technically a polar desert.

Extremely cold can prevent water from forming clouds, and strong wind blows away any humidity. This makes it the dry place on the earth.

Why is Antarctic the drying mainland?

Antarctica is the drier continent on the planet. Due to its low precipitation, strong wind and extremely cold. Although it is covered by ice, it is classified as the polar desert. Why:

1. Extremely low precipitation

The annual precipitation of Antarctica in certain regions is less than 50 mm each year. That is even less than the Sahara desert! Most water is locked in ice, and there are few snowfall in many areas.

2. Strong Katabata Wind

The cold, dense air flows from the high interior of the Antarctic, and the Katabative wind is generated. These winds blow away water, preventing cloud formation and rainfall.

3. Frozen temperature

The extreme cold of Antarctica frozen water. Evaporation and condensation are small, reducing the chance of precipitation.

What are the most dry places in Antarctica?

The most dry place in Antarctica is mainly located in McMurdo Dry Valleys. It is a unique area, which is characterized by extremely low humidity and extremely small precipitation. This is the most dry place:

1. McMurdoan Valley

The region is usually considered the dry place on the planet, and some areas have not rained in nearly 2 million years. The valley is largely snowy, which is because the Katabatic wind evaporates any possible water.

2. Taylor Valley

Taylor Valley is located in McMurdo Dry Valleys. It is famous for its unique geological characteristics and is very low to help its drought conditions. It contains Lake Bonney, which is covered by ice and has a high salinity level.

3. Van Da Lake

This salt lake is also located in Taylor Valley. It is famous for its extreme salinity. It is more salty than seawater and has almost no precipitation. The lake was permanently covered by ice, which further contributed to the dryness of the area.

4. Lake Fredis

Another lake in McMurdo Dry Valleys, Lake Fryxell is surrounded by the mountains, the mountains block the water, making it one of the most dry places in Antarctica. Like other lakes in the area, it is covered by ice and has the least fresh water flow.

5. Agate

As the longest river in Antarctica, the Agate River flows through the dry valley in the melted summer of glaciers. However, the overall drought in the region has almost no contribution to the local water level.
