The earth, the moon, humans, seasons, etc. are all surrounded by nature. All things in the world grow and flourish as the earth revolves and rotates. What would happen if there was no winter on earth? What would happen if the earth stopped rotating for one second? Let's read on! Contents of this article 1. What would happen if the earth stopped rotating for one second? 2. What would happen if the Earth had no winter? 3. Why the Moon Won’t Collide with the Earth 1What would happen if the earth stopped rotating for one second?Mountains and rivers change, stars move, and everything in the world grows and flourishes with the earth's revolution and rotation. If the earth stops rotating for one second, all peaceful lives will be destroyed. The earth rotates at a speed of 400 meters per second. If it stops for one second, people will be easily blown away by the strong wind and the roaring waves. If the earth loses its magnetic field, people will also lose their homes. 2What would happen if the Earth didn't have winter?If there is no winter on Earth, humans will face serious problems: 1. The glaciers in the Arctic and Antarctic are melting, the sea level is rising, and the land area is greatly reduced. 2. If humans cannot adapt to the virus and produce corresponding antibodies, they will become extinct. 3. Most rivers will have to be diverted because the source of most large rivers are glaciers. 4. Humans can only survive in the mostly humid tropical lowlands with very low population density supported by very unstable agriculture. Low population density and low agricultural productivity lead to small-scale, scattered villages. None of the pleasant things in modern civilization can be built on this foundation. 3Why won't the moon hit the earth?The reason why the moon will not hit the earth: there is centrifugal force when the moon revolves around the earth, and there is universal gravitation between the earth and the moon. The centrifugal force and universal gravitation have reached a state of equilibrium, so the moon will not hit the earth. The concept of centrifugal force: Centrifugal force is a virtual force, a kind of inertial force, which makes a rotating object move away from its center of rotation. The concept of universal gravitation: All objects in the universe attract each other. The magnitude of the gravitational force between two objects is proportional to the product of their masses and inversely proportional to the square of their distance. The direction of gravity is along the line connecting the two objects. |
