What life is in the desert and what dangers are in the desert

There are rats and lizards underground.

As follows:

1. Disorientation.

2. Animals that cause harm to themselves.

3. Quicksand and dust storms.

Fourth, the weather changes, the morning is very hot, and the night is cold, which may cause the body to be uncomfortable.

5. Dehydration due to strong light exposure! You may be unconscious, and if you are really unconscious, you may never be able to get out.

6. Man-made robbery and injury! This happens a lot on the edge of the desert.

7. Loss of luggage This is also the most common occurrence in the desert.

Features of the tropical desert climate:

1) Low precipitation and high variability: Asven in the Sahara Desert of North Africa has recorded no rain for many years; In Arica, in the desert north of Chile in South America, there have been only three measurable showers in 17 consecutive years, and the total amount of the three rainfall is only one millimeter, and the precipitation is very low.

Iquigui, also located in the northern desert of Chile, had no rain for four consecutive years, but in the fifth year a shower fell 15 millimeters, and in another year a shower record reached a metric centimeter, which shows the magnitude of variability. Rainfall in tropical deserts is often bursting showers, often causing severe soil erosion.

2) High temperature and large temperature difference: due to the lack of clouds, strong sunshine, lack of vegetation cover, and low air humidity, the temperature rises very quickly during the day. In North Africa, there has been a record of as high as 58, and the average monthly temperature in summer is generally between 30 and 35, and the high temperature is very long, such as Aden in the Arabian Peninsula, where the average monthly temperature is above 30 for five months of the year.

The night in the desert is cooler, because there are no clouds all night, the ground radiation is strong, the heat dissipation is fast, the minimum temperature at night is generally between 7 12, and there are also days of thin frost. The annual temperature difference is generally around 10 20, while the daily temperature difference is even greater, between 15 and 30. A meteorological station south of Tripoli in North Africa.

On December 25, 1978, there was a record of the hottest during the day and the lowest temperature at night.

3) Strong evaporation and low relative humidity: The tropical desert climate is very strong because it is often cloudless, windy, sunshine, high temperature and low relative humidity. Evaporation may be more than 20 times the amount of precipitation, or even 100 times the amount of precipitation.

The relative humidity in the air is very small, and in the Egyptian Sahara Desert it is common to experience a relative humidity of about 2%.

Danger in the desert:1. Disorientation.

2. Animals that cause harm to themselves.

3. Quicksand and dust storms.

Fourth, the weather changes, the morning is very hot, and the night is cold, which may cause the body to be uncomfortable.

5. Dehydration due to strong light exposure! You may be unconscious, and if you are really unconscious, you may never be able to get out.

6. Man-made robbery and injury! This happens a lot on the edge of the desert.

7. Loss of luggage This is also the most common occurrence in the desert.

Here's how to identify directions in the desertDuring the day, we know that the earth revolves around the sun from east to west, so we can use the sun to judge and insert the rod to see the shadow, so that the two points of the shadow head are linked, and a vertical line is drawn in the middle, which is north and south. At night, you can look at the constellations, there are many constellations that can discern the direction, and the Big Dipper can distinguish the north. The moon revolves around the east and west of the earth, and it can also give people directions.

Wind is an important factor in shaping the shape of the desert ground, in the northwest of China, due to the prevailing northwest wind, the sand dunes generally form a southeast direction, and the northwest side of the sand dunes is the windward side, with a small slope and hard sand. The southeast side is leeward, with a steep slope and soft sand. In addition, the plants in the desert, such as red willow, saxon, camel thorn, etc., all slope to the southeast.

Finally, if we go out, we must bring all our equipment, and when we go to the desert, we must bring life-saving equipment such as a compass so as not to get lost.

The desert is home to camels, gerbils, lizards, scorpions, rattlesnakes, ants, sesame snakes, ostriches, elephants, lions, wolves, and other animals. Some of the small animals in the desert have drought-tolerant physiological characteristics. They do not need to drink water, can obtain water directly from the plant body and rely on special metabolic methods to obtain the required water, and have a series of physiological and ecological adaptation mechanisms in reducing water consumption.

Desert mainly refers to a barren area where the ground is completely covered with sand, plants are very scarce, rainfall is scarce, and the air is dry. The desert is also known as the "sand curtain", an area where there is a shortage of water and few plants. The desert area is mostly sandy beaches or sand dunes, and rocks under the sand are often found.

Some deserts are salt flats and completely devoid of vegetation. Deserts are generally aeolian landforms. There are sometimes valuable mineral deposits in the desert, and many oil deposits have been discovered in recent times.

The desert is rarely inhabited, and the resources are relatively easy to exploit. The desert has a dry climate, and it is also a happy place for archaeologists, who can find many human artifacts and earlier fossils.

The scorching sun was scorching, and walking in the vast desert, the feeling of emptiness and remoteness filled the chest. The undulating sand dunes are as soft as the curves of the waves, and after the strong wind, the dunes are carved with ripples, like ripples on the surface of the lake.

The most shocking thing is the occasional beetle and a small clump of greenery in the desert, adding a touch of life and vitality to the desolate and silent desert.

I have to sigh at the strong vitality, the arid and water-scarce Kubuqi Desert, the surface temperature is as high as more than 40 degrees these days, and there are still plants and insects growing tenaciously.
