Is approximately one third of the earth land surface is desert
How much of the Earth's land surface is covered by desert Approximately one-third of the Earth's land surface is classified as desert. Deserts are regions that receive very little precipitation, typically less than 250 millimeters (10 inches) of rain per year.
What makes a desert a desert
Most experts agree that a desert is an area of land that receives no more than 25 centimeters (10 inches) of precipitation a year. The amount of evaporation in a desert often greatly exceeds the annual rainfall. In all deserts, there is little water available for plants and other organisms.
Why is the desert important
Deserts provide many benefits that can meet the demands of both the local inhabitants and other surrounding communities. These benefits include water, food supply, medicine and raw materials.
Which country 90% is desert
Libya’s
Libya's climate is Mediterranean along the coast and dry in the desert interior; more than 90% of the country is desert or semidesert.
In which country is 95% of the land covered by desert
In the Arabian Peninsula's hot, dry climate, dust storms are anything but rare. Saudi Arabia is 95 percent desert. Rub' Al Khali, the biggest desert in the Arabian Peninsula and one of the largest sand deserts in the world, occupies southern Saudi Arabia.
Why are deserts hot
With the relative lack in moisture, there is less evaporation. There are also less clouds to reflect the sunlight away. With no evaporative cooling and a relative lack of vegetation to use the sunlight, most all of the sunlight goes into warming the ground surface. This causes very hot afternoon temperatures.
Do deserts get cold at night
During the day, desert temperatures rise to an average of 38°C (a little over 100°F). At night, desert temperatures fall to an average of -3.9°C (about 25°F).
Why do deserts have sand
Sand consists of small particles of larger rock that's been eroded. But erosion doesn't happen fast enough in arid environments to be the only cause of desert sand. Nearly all sand in deserts came from somewhere else – sometimes hundreds of kilometers away.
What lives in a desert
In deserts, you'll usually see a lot of open soil and rocks and not much grass or other kinds of plants. Animals that live in deserts include lizards, geckos, toads, jackrabbits, camels, snakes, spiders and meerkats.
What 11 countries touch Sahara Desert
The Sahara desert touches eleven countries – Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Sudan, Tunisia and Western Sahara.
What country has desert first
The European Way. According to Brandi Milloy, a TV host and apparent lifestyle and parenting expert, Germans eat dessert first. This claim refers to a time when her family was living in Germany. Her dad served in the US army and curious to adopt the European way of eating, her family often had dessert first.

The Sahara desert

How cold is Antarctica
The coldest temperature recorded in Antarctica was -89.6°C at Vostok station in 1983. The average winter temperature at the South Pole is about -49°C. Your home freezer is only about -15°C. The wind chill factor means that it can feel much colder.
Does rain fall in desert
In fact, the most important characteristic of a desert is that it receives very little rainfall. Most deserts receive less than 300 mm a year compared to rainforests, which receive over 2,000 mm. That means that the desert only gets 10 percent of the rain that a rainforest gets!
Why is the Sahara so hot
The Sahara desert lies along the Tropic of Cancer. However it is hotter than other regions lying on the same latitude. The reasons for Sahara being hot are scanty vegetation, low water vapour content in the atmosphere (Humidity) and low water content in the soil.
Is desert sand or dirt
Desert soils are downright unusual! They vary tremendously in texture; many are sandy and gravelly, while others contain layers of sticky clay, or even rock-hard, white limy layers. Desert soils may be gray-colored, brown, or even brick red.
Is Antarctica a dessert
Antarctica is a desert. It does not rain or snow a lot there. When it snows, the snow does not melt and builds up over many years to make large, thick sheets of ice, called ice sheets. Antarctica is made up of lots of ice in the form of glaciers, ice shelves and icebergs.
Do lions live in desert
Lions are highly adaptable and can live in very dry areas like the Kalahari Desert.
How many animals live in the deserts
What animals live in the desert Many birds, reptiles, mammals and insects live in the desert. In the Sonoran Desert (Arizona, US) alone, there are over 500 bird species, 130 mammal species, 100 reptiles species and more than 2,500 plant species! Here are some examples of the most common desert animals.
What 4 countries are in the Sahara
The Sahara desert is the largest hot desert in the world. The Sahara desert covers 10 different countries — they are Algeria, Chad, Egypt, Libya, Mali, Mauritania, Niger, Western Sahara, Sudan, and Tunisia.
How big is the Sahara desert
9.2 million km²
How Big Is The Sahara Desert The Sahara Desert is the largest hot desert in the world, and the third largest overall after the Antarctica and the Arctic. The Sahara Desert covers an incredible 9.2 million km², which is almost the same size as China, and a total of 8% of the earth's land area.
How old is the oldest desert
55 million years
Dating back at least 55 million years, the Namib is believed to be the world's oldest desert (the Sahara is thought to be just two to seven million years old).
Is Russia colder than Antarctica
Top 5 Coldest Places on Earth
Antarctica takes the title for the top 4 coldest places on earth, but Russia and Greenland aren't far behind Alaska, with lows of -69.8°C (-93°F) and -69.4°C (-92.9°F) respectively. Antarctica may be cold, but it's far from the coldest environment humans have endured.
How wet is Antarctica
What little precipitation there is mostly falls as snow, averaging less than 50mm a year (water equivalent) across much of the interior. This is in the 'hyper arid' category, shared with the Sahara, Namib, Atacama, and other great deserts of the world.
Does it rain in Dubai
It mostly rains during the winter period between November and March in the form of short downpours and an occasional thunderstorm. On average, rain falls only 25 days a year. February is the wettest month in Dubai with an average of 35 mm (1.4 in) of rain.
