Difference between Desert and Desert

What is desert?

The desert is a region characterized by a hot, dry and harsh climate . The average rainfall here is very low, about 200-250mm / year but the amount of evaporation is very high from 900 to 1500mm above the open water surface.

Therefore, there are rare rivers and streams in the desert. Therefore, only animals and plants with very high drought tolerance can adapt and survive here.

Plants here are mostly drought resistant and adaptable to harsh environments.

1. These plants have a short life cycle during the rainy season and seeds can survive in the long dry season.
2. Succulent plants like cacti, which can store large amounts of water, turn into spikes to minimize dehydration.
3. Large trees, with deep turns to the deepest ground to absorb water.

The fauna here is quite rich from small species such as scorpions, geckos to big species like hyenas, foxes, curly horny antelopes, camels . These are all resistant species. hot, high thirst. In order to survive in harsh circumstances, they often hunt, feed in the evening, and stay in caves or under the sun during the day.

Based on the nature, scientists divided four different types of desert:

1. Desert clay
2. Sand desert
3. Desert salt soil
4. Desert hills.

What is a desert?

Almost desert, desert is also a place with harsh climate with very little rainfall. But the climate, the weather, the desert conditions are much more harsh than the desert.

Less rainfall, greater evaporation due to higher temperatures, air humidity is almost zero. Also the amount of solar radiation in this place is extremely large. Very high day and night difference temperatures can reach 80 ° C.

This makes it impossible for most plants and animals to withstand drought, heat, and high thirst. Only extraordinary drought-resistant animals like camels can survive.

Perhaps quite a lot of people are surprised to learn that Antarctica is the largest desert in the world. It is 1.5 times wider than the famous Sahara desert.

Up to 99% of the area of ​​Antarctica is covered by ice, the average temperature is only around -48 ° C. Due to the harsh living environment, plants cannot exist here. Animals are also very few, most famous, including seals.

2. Sahara - 8.6 million km²

The Sahara is the largest sand desert in the world and is rated by the experts as the harshest desert in the world. There is almost no vegetation to retain heat, so when the night falls, the temperature drops quickly and deeply, making the temperature difference very high.

3. Arabian desert - 2.3 million km²

The Arabian desert is uneven in the regions, in the desert center with temperatures of up to 54 ° C, in areas near the edges, it is wetter, sometimes covered with fog. The rainfall here also depends on different areas where the place is just under 100mm / year, there are also places up to 500mm / year. And there are areas thanks to human irrigation that part of the desert has been greened again.

4. Gobi - 1.3 million km²

Gobi is Asia's most famous desert, covering a large area of ​​Mongolia and China. Although it is a harsh desert, in some special places, the weather is divided into two distinct rainy and dry seasons, not hot and dry all year round.

In the Gobi desert, a fossil skeleton of T-Rex was discovered. According to archaeologists, this is the ideal place to excavate dinosaur fossils. Besides, Gobi still has many hidden mysteries associated with rumors about UFOs and aliens.

5. Kalahari - 930.00 million km²

Kalahari ranks fifth on the list, which spans a large area of ​​South Africa, Botswana and Namibia. The amount of water received is still higher than many other deserts even at only 500mm / year
