Geographical incomprehension, geographical unsolved mystery

The Congo Basin is low-lying and affected by warm currents, so the equatorial low pressure is controlled for a long time, which can form tropical rainforests.

Although East Africa is about the same latitude, it has high terrain, it is difficult for water vapor to climb, and the precipitation is small, so tropical savannahs are formed.

The fundamental difference between these two places lies in the difference in terrain.

The Congo Basin has low terrain, good accumulated temperature conditions, high temperature, and abundant precipitation, forming a tropical rainforest area, while the East African Plateau has a high altitude and low temperature compared to the Congo Basin, which is not easy to form convective rain, so it forms a savannah climate.

As long as you grasp the essential difference between the two, problems like this can be easily solved.

The East African Plateau and the Congo Basin are both near the equator, but the Congo Basin is in the western part of the continent, the terrain is low, and it is under the control of the equatorial depression all year round, blowing southwest winds, high temperature and rain, and becoming a tropical rainforest climate. The East African Plateau is located in the eastern part of the continent, in the northeast of the center of the African thermal low pressure in January, blowing northerly and northeasterly winds with little rainfall; In July, the southwest winds over the Atlantic Ocean crossed the Congo Basin and brought little precipitation to East Africa, so the annual precipitation in the East African plateau was not as high as that in the Congo Basin, and there were periods of significant lack of rainfall. In addition, the altitude of the East African plateau is relatively high, generally around 1,000 to 1,500 meters, and the temperature is greatly reduced, so the vegetation is dominated by the savannah type with small forests and banded forests, and the tropical rainforest area is very small, and it is only distributed on the low slopes of the humid foothills and the western part of the plateau near the Congo Basin.

First of all, the Congo Basin is fed by the Congo River, which has a large runoff and a large amount of evaporation. In addition, the Congo Basin is near the equator and is greatly affected by the equatorial depression. The East African plateau, on the other hand, is vertically differentiated, with high altitude, low temperature, and no hydrothermal conditions for the formation of tropical rainforests, which means that the precipitation is not enough and the convection is still weak.

The surface temperature of the altitude is relatively low, although the latitude of the two places is about the same, the temperature of the plateau is relatively low, and there is not such a strong updraft, so it is not a tropical rainforest.

The main reason is that the Congo Basin is prone to topographic rain due to the influence of topography; The East African plateau is affected by dry airflows from the continent and has little rain all year round.

The Four Great Valleys of Death.

The "Valley of Death" in the Kronotee Mountains of the Kamchatka Peninsula of the former Soviet Union is two kilometers long and 100,300 meters wide. The terrain here is uneven and potholes, and in many places there are natural sulfur and phosphorus outcropping from the ground. The bones of bears, wolverines and other beasts were everywhere, and it was a desolation.

According to statistics, this "valley of death" has swallowed more than 30 lives. Scientists from the former Soviet Union have conducted many expeditions to this "Death Valley", but the conclusions are still divided. It has been suggested that the main culprits of the killing of humans and animals are hydrogen sulfide and carbon dioxide that accumulate in deep pits.

Others believe that the fatal cause may be the potent agent hydrocyanic acid and its derivatives. However, the peasants living in villages just a stone's throw from Death Valley and without mountains and forests have not been affected by these poisonous gases.

Among the mountains bordering California and Nevada in the United States, there is also a huge "Death Valley". It is 225 km long. It is about 6,26 kilometers wide and covers an area of more than 1,400 square kilometers.

The cliffs on both sides of the canyon are very treacherous. It is said that in 1949, there was a gold exploration team in the United States, which was disoriented and involved in it, and almost all of the team was wiped out. A few who were lucky enough to escape also died mysteriously soon after.

Since then, some of the people who went on expeditions have also been buried in the valley repeatedly, and the cause of death has not been found out to this day. However, scientists have discovered that this hellish "valley of death" is actually a "paradise" of birds and animals. According to survey statistics, there are about 200 species of birds, 19 species of snakes, 17 species of scorpions, and more than 1,500 wild donkeys that are actually leisurely and comfortable here.

To this day, no one can figure out why this canyon is so kind to humans and so kind to animals.

The "Valley of Death" near Naples and Lake Vaverno in Italy has another character. It only harms birds and animals, but it poses no threat to human life. According to surveys, more than 37,600 animals die here every year.

That's why the Italians call it the "graveyard of animals". Some experts and scholars in Italy have conducted investigations and studies on the "Death Valley" many times, but they have not yet found the answer.

On the Indonesian island of Java, there is an even more bizarre "Death Valley". There are 6 huge caves scattered throughout the valley, each of which poses a great threat to the lives of humans and animals. If a person or animal is 6 or 7 meters away from the entrance of the cave, he will be sucked into the cave by a magical attraction and will be buried.

So the cave is still full of lions, tigers, wild boars, deer and human bones. How do these caves have such the power to absorb living beings? What are the reasons for the deaths of the people and animals that were sucked in?

Lake Superior in North America is the largest freshwater lake in terms of area, and Lake Baikal is the deepest freshwater lake in the world.

Because the equator passes through the East African Plateau of the African continent, the terrain is high, and it is not easy to form convective rain, so only the low-lying places like the Congo Basin form tropical rainforests, and the equatorial region of the East African Plateau forms a savannah climate, and because the East African Plateau is vast, the savannah climate is the most widely distributed, and the Amazon Plain, the equatorial crossing area of South America, is the world's largest tropical rainforest.

1. The largest freshwater lake in North America is Lake Superior. Lake Baikal is the deepest lake in the world.

2. The equator crosses its middle, and the land distribution is almost symmetrical in the northern and southern hemispheres; The plateau has a large area and relatively flat terrain.

1.Lakes in Asia are not widely distributed. Lake Baikal is the deepest lake in the world, and the largest freshwater lake in the world is Lake Superior.

2.First of all, most of the African region through which the equator passes is a tropical rainforest climate, because it is in the equatorial low pressure zone, where updrafts prevail and precipitation occurs, and the savannah climate in the east is because of the cold current in Somalia along the coast, which cools down and dehumidifies. The desert landscape of Africa is located at about 10° 20° north and south latitude, because it is a subtropical high pressure zone, where downdrafts prevail and precipitation is low; And under the influence of the trade winds, seasonal precipitation is produced, which is divided into two distinct seasons: dry and wet.

1 False, Lake Baikal is the deepest and not the largest, the savannah is distributed between 10 and 20 degrees north and south latitudes, and Africa is the largest in this range, as you can see if you look at the map.
