World geography is wonderfully endless, there will always be classes will not involve the cold knowledge is not familiar to us, but many world geography cold knowledge is very interesting, and even some times can help us to some extent, let us take a look at these few world geography cold knowledge!
Africa is hot in summer, but cold in winter
Although it is said that the highest temperature in Africa can reach 58.8 degrees, but the lowest temperature in Africa is only -23.9 degrees, which is close to many high latitude areas. Although the equator runs through the north-central part of Africa, and 3/4 of the continent is exposed to the sun's vertical rays, and the tropics with an annual average temperature above 20 degrees Celsius account for 95% of the continent, some areas are outside these regions.
In addition to latitude, altitude is what makes low temperatures low. In addition to the high temperatures in summer, Africa's winters are also surprisingly cold, with temperatures in the coldest areas dropping below zero.
Although Lake Baikal is a lake, it has a lot of marine life
Baikal is the world's deepest lake, with a maximum depth of 1,642 meters and an average depth of 758 meters. The total volume of the water body is 23,600 cubic kilometers, which is equivalent to the sum of the water of the Great Lakes in North America and more than the water of the entire Baltic Sea, and its absolute net water reserves account for 20% of the world's fresh water reserves.
Although the water of the lake is fresh water, there are a large number of seals, sharks, lobsters, sponges, conchs and other marine animals living here.
Saudi Arabia is not the country with the largest oil reserves
I believe that many people subconsciously believe that Saudi Arabia is the world's largest oil reserves, after all, there are so many oil barons here. But in fact it is not, the world's largest oil reserves in the country is South America's Venezuela, the country's Lake Maracaibo region is one of the world's most important oil-producing areas.
According to the data, Venezuela's recoverable oil reserves are about 296.5 billion barrels, which is 30 billion barrels more than Saudi Arabia. In addition, Canada's theoretical oil reserves are the second largest in the world, also above Saudi Arabia, but the current extraction volume is not large, so it is not too conspicuous.
The world is full of wonders, and there are more amazing aspects waiting for us to explore!
