Dry Valleys facts

While investigating facts about Dry Valleys Antarctica and Dry Valleys Antarctica Rainfall, I found out little known, but curios details like:

The driest place on earth is McMurdo dry Valleys in Antarctica where it hasn't rained for 2 million years. Only anaerobic bacteria are able to survive in the extreme conditions. Scientists also consider the area terrestrially closest to Mars on earth.

how are dry valleys formed?

Not all of Antarctica is covered with ice; the continent also has ice-free dry valleys featuring bodies of water - hypersaline ponds - that never freeze, even in the depths of winter.

What are dry valleys in antarctica?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what causes the dry valleys in antarctica. Here are 17 of the best facts about Dry Valleys Roofing and Dry Valleys Antarctica Temperature I managed to collect.

what are dry valleys?

1. The driest place (precipitation) on Earth is, ironically, in Antarctica. The Dry Valleys haven’t received rain in nearly 2 million years!

2. Despite its hot and dry climate Death Valley is home to a diverse range of fauna (which grows after it rains), more than 300 bird species, as well as many different species of lizards, snakes, reptiles, amphibians and even bighorn sheep and mountain lions.

3. With a salt concentration of more than 33% it is one of the saltiest water bodies on earth. The Caspian Sea's Lagoon Garabogazkol, and Antarctica's Lake and are saltier at 35%, while Antarctica's McMurdo Dry Valleys is 44% salinity.

4. The Sahara Desert is made up of sand dunes, sand seas, gravel plains, stone plateaus, dry valleys, salt flats, mountains, rivers, streams, and oases.

5. At the Dry Valleys, Antarctica, the driest place on earth, downward cold winds called katabatic winds can reach 200mph (322kph), evaporating any water, ice or snow

6. Wind and occasional rain are responsible for forming the landforms in the Sahara, which include sand dunes, dune fields, salt flats, and dry valleys. Land formations change regularly.

7. The climate of Death Valley is created because of the mountains on all sides which trap dry, hot air masses.

8. The Don Juan Pond in the Dry Valleys of Antarctica is saltiest body of water on Earth and is 18 times saltier than that of an ocean.

9. The "dem bones, dem bones gonna walk around" song is actually a spiritual song, inspired by Ezekiel 37:1-14, where the Prophet visits the "Valley of Dry Bones" and prophesies that they will one day be resurrected at God's command, picturing the national resurrection of Israel.

Why are dry valleys formed?

You can easily fact check it by examining the linked well-known sources.

The Mcmurdo Dry Valleys, an ice-less desert in the Antarctic, no rain for 2 million years

Saudi Arabia, United Arab Emirates, Qatar, Kuwait and 14 other countries don't have any rivers. Instead, many of these nations have "wadis", which are dry valleys that fill up with water during the rainy seasons. - source

Many people in Montana consider the "summer of 2000" "as an 'unforgettable' fire season. In the Bitter Root Valley,the firestorm started on July 31 [from a dry lightning storm] and continued to blaze into September." It was seen "as one of the largest natural disasters in the state's history." - source

Google Maps have amazingly extensive Street View panoramas of McMurdo Dry Valleys and McMurdo Station in Antarctica - source
