1, Congo Basin has a tropical rain forest climate, and its edge has a savanna climate, so the overall precipitation is very rich, not naturally dry as mentioned on the first floor. The landlord remembers that the main reason for serious desertification is human activities. That place is a savanna, a rainforest. Overgrazing of savanna, deforestation of rainforest and development of tropical immigrant agriculture (which is very harmful to the natural environment) are the main reasons. Of course, abnormal climate is also one of the reasons, but it is secondary to human activities.
2. The fishing grounds in the Southeast Atlantic are similar to those in the Southeast Pacific (near Peru), all of which are due to the rise of the compensation current (natural cold current, Benguela cold current in the Southeast Atlantic and Peru cold current in the Southeast Pacific, all of which are famous big cold currents), bringing bait from the seabed to the upper waters and bringing cold-water fish up, thus forming a fishing ground.
Iceland is the country with the richest geothermal resources in the world. Because Iceland is located in the mid-Atlantic ridge, it is the growth boundary (tension zone) between the American plate and the Eurasian plate, and the magmatism is very strong, forming geothermal energy.
4. Eastern Europe Plain is a concentrated area of population and grain production in Russia, but it is not a concentrated area of military industry. Its military industry is concentrated in Siberia.
Taking China as an example, the latitude of winter wheat generally ranges from the Yangtze River basin in the south to the Great Wall in the north. But it is also found in the northeast of South China, which is hard to say. The overall distribution range is around 30 degrees-south of 45 degrees.
6. Fog is different from rain, but it also has the same cause.
Fog: firstly, the temperate maritime climate is very humid and full of water vapor; Secondly, the summer is cool and the temperature is low, which leads to the condensation of water vapor in the air and the formation of fog.
Rainwater: The area is controlled by prevailing westerlies all the year round, bringing a lot of warm and humid air currents from the Atlantic Ocean, resulting in rainy weather; Secondly, the cyclone activity in this area is very frequent, and the precipitation type is cyclone rain (also known as typhoon rain, which is also called the four major precipitation types with convective rain, frontal rain and topographic precipitation).
7. Two necessary conditions for skiing: one is snow, and the other is slope.
First of all, it has a temperate continental climate with cold winters.
Second, the place is near the sea, with plenty of water vapor and a lot of snowfall in winter.
Third, the area is located in the mountainous area, with more snow and suitable slope. So it is suitable for skiing.
