How does Camel survive in desert?
Camels have adapted and found ways to help them survive in deserts. They have a thick coat of hair that protects them from the sun. They have wide, soft feet, so they can walk for a long time in the hot sand. When there is food and water, a camel can eat and drink large amounts of it and store it as fat in the hump.

How hot is the desert?

Where are desert climates located?
Hot desert climates. Hot desert climates (BWh) are typically found under the subtropical ridge in the lower middle latitudes often between 20 and 33 north and south latitude.
How are deserts formed?
Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks which consequently break in pieces. Rocks are smoothed down, and the wind sorts sand into uniform deposits. The grains end up as level sheets of sand or are piled high in billowing sand dunes.
Is there life in Antarctica?
No humans live in Antarctica permanently. However, about 1,000 to 5,000 people live through the year at the science stations in Antarctica. Only plants and animals that can live in cold live there. The animals include penguins, seals, nematodes, tardigrades and mites.
Is Antarctica livable?
Antarctica is the only continent on Earth without indigenous human inhabitants. At present scientists and staff from 30 countries live on about 70 bases (40 year-round and 30 summer-only), with an approximate population of 4,000 in summer and 1,000 in winter.

Why does the Atacama desert get no rain?
The Atacama is a desert not because mountains make a rain shadow, but because the ocean does. The water on the west part of Chile is quite cold, because it came from Antarctica. Moisture cannot stay in the cold air above the cold water, so mainly fog reaches the land, but very little rain.
How long did each mass extinction last?
Later, species diversify and occupy empty niches. Generally, biodiversity recovers 5 to 10 million years after the extinction event. In the most severe mass extinctions it may take 15 to 30 million years.
