What plants and animals live in deserts? What causes tropical desert climate?

Deserts are also called sand curtains. They are mainly barren areas where the ground is completely covered with sand, with very few plants, little rain, and dry air. Deserts are generally wind-formed landforms, mostly sandy beaches or sand dunes, and rocks often appear under the sand. Let's learn about the flora and fauna and climate of deserts.

What plants and animals are there in the desert?

The plants in the desert include Cistanche, Aloe, Tianlun Pillar, Welwitschia, Ammopiptanthus, Golden Amber, Sea Buckthorn, Green Bell, Red-skinned Sand Date, Lithops, Starfish, Haloxylon ammodendron, Cacti, and White Thorn. The animals in the desert include snakes, rats, sand lizards, camels, ostriches, scorpions, etc.

A desert refers to a barren area where the ground is completely covered with sand, plants are very scarce, rain is little, and the air is dry. Deserts are generally aeolian landforms, mostly beaches or sand dunes, and rocks often appear under the sand.

The climate in the desert is dry, with drastic changes in temperature and strong sunshine. The plants growing in this environment have relatively developed root systems and their leaves degenerate into needles. The most important thing is that they are more drought-resistant than ordinary plants.

Desert animals have the ability to retain water and resist high temperatures, as well as morphological characteristics that are adapted to desert life. They can use water from the decomposition products of organic matter and have a much greater tolerance to hunger than their related species.

What causes tropical desert climate?

The causes of tropical desert climate are: 1. Controlled by the subtropical high pressure belt. 2. Controlled by dry trade winds. 3. Affected by cold currents. The subtropical high pressure is a dynamic high pressure. It is formed by the continuous flow of air above the equator to the subtropical sky, which accumulates and generates downdrafts, causing the low air pressure to increase. It is a warm high pressure.

Tropical desert climate is distributed in the interior or west coast of the continent between the Tropic of Cancer and the Tropic of Capricorn and 30° north and south latitude, and extends to inland areas. Typical examples include northern Africa, the Arabian Peninsula in Asia, and the desert areas of Australia.

The tropical desert climate has many characteristics, such as frequent sunny days, strong sunlight, dryness, hot summers, large temperature differences between day and night, and lots of wind and sand.

The Sahara Desert and Kalahari Desert in Africa, the Arabian Desert and Thar Desert in Southwest Asia, the western and central deserts of Australia, the deserts in California, and the Atacama Desert in South America all have typical tropical desert climates.

The dangers of desert turning into oasis

There is no big harm if a small area of ​​desert turns into an oasis. However, if a large area of ​​desert turns into an oasis, the global climate will change dramatically and the existing ecosystem will be destroyed. When desert turns into an oasis, the oxygen content in the air will increase, the carbon dioxide will decrease, the earth will drop to a low temperature, animals will change dramatically, causing animal extinction, and endangering human survival.

A desert, also known as a sand curtain, mainly refers to a barren area where the ground is completely covered with sand, plants are very scarce, rain is rare, and the air is dry.

One third of the earth's land is desert. There is very little water in the desert. Most people think that the desert is desolate and lifeless, so it is called "desert".

Among China's eight famous deserts, the Taklimakan Desert covers an area of ​​320,000 square kilometers. It is the largest desert in China and one of the world's famous deserts.
