How deep is Takla Makan Desert? If you dig up all the sand, what's under it?
Earth has oceans and land, but land is also divided into various natural landforms, including familiar mountains, plains, hills, and deserts. The reasons for formation of these landforms are also different: mainly divided into two types, one of which is associated with supernatural skill of nature, such as movement of plates;
Another category is anthropogenic factors caused by human activity. Each landform has its own climate and ecosystem. Today, we mainly represent natural landform, that is, desert.
For many, impression of desert is that it is deserted and deserted, without greenery, without a source of water, and even with raging yellow sand, so neither animals live here, let alone people, but there are some people who are very fond of and yearn for her. This lonely beauty of desert. Together with needs of human life, their destruction of environment has led to emergence of more and more deserts, and area of deserts is also constantly increasing.
The desert that we will present today should be familiar to everyone, it is a very large desert. Takla Makan Desert. For this big desert, some people wonder: if there is no sand in desert, what will be at bottom?
1. A place in desert
The desert is located in Xinjiang region of our country. Coincidentally, it is located in center of Tarim Basin, so it is surrounded by high mountains, forming a terrain that is high in west and low in east. The total area of the desert is about same as that of Yunnan Province in our country, so it is still very large in our country.
Second, desert climate
Takla Makan Desert naturally belongs to desert climate, summer temperature is very high and precipitation is very low, highest temperature can reach almost 70 degrees, not so whether? think of Flame Mountain in Journey to West.
This place not only has little rainfall in summer, but very little rainfall throughout year, not to mention some special dry years, and temperature difference between day and night in desert is extremely large, which has also affected some areas. in Xinjiang. You can see how difficult and harsh conditions are here.
Third, desert characteristics
Compared to harsh natural conditions, Taklamakan desert impresses with its thickness and depth. This is a very special area, we learned about unique existence from books, meaning it can flow freely.
When wind blows, they will move with wind, and wind will blow them together, even reaching thousands of meters at highest point, which is extremely important for desert animals or desert explorers. dangerous.
Fourth, what is under desert
What lies under such a dense desert? Small animals are often found here in sandy layer. Is there another biological world? This is also an interesting answer, but objectively speaking, there will certainly be no life underground, but bottom of this desert is really a huge wealth.
1. Oil. The most valuable, in addition to precious stones and diamonds, is oil, which is also a natural resource. But it may seem to someone that this is impossible, because oil, as a rule, is located near ocean, and here, in desert, it is all more impossible. However, everyone who has studied geography knows that hundreds of millions of years ago our earth was an ocean with extremely scarce land, at that time it had many species of organisms and valuable resources.
Slowly earth changed. The desert location has very good sedimentation conditions. After movement of plates, various natural landforms appeared, forming current Takla Makan desert, and because of this, oil was buried. Also just a guess.
2. Water Resources: There is another suggestion that water resources are different from oil resources. This is even more incredible than above assumption, isn't it, but source of water here is groundwater.
We can't see their stream because they are too deep. The main source of this groundwater is melt water from snow on icebergs. However, difficulty of harvesting water in desert is even more difficult, and modern technology fails to grasp this. .
3. Ordinary earth. There is also practical assumption that if all sand in desert is dug up, it will be most common layer of bedrock, same as other landforms on Earth. Earth. Of course, there will be some valuable things, such as remains and skeletons of animals in antiquity or skeletons of people who have not survived desert expeditions for generations, buried in sand.
Another example is fossil record, which records most numerous species in most primitive era. There are also ancient cities depicted in book, such as Loulan Ancient City and Jingjue Ancient City, etc., but as weather gets worse and worse, these places are no longer survivable and will disappear into history forever.
Even if real scientists now discover that there are abundant resources under this desert, we will not be able to prove it, because with current technology it is impossible to dig sand, let alone where a large amount of sand dug accumulates, Only when our technology is getting more and more advanced, and technology is getting more and more advanced, maybe it can be realized.
