We will try to answer some senseless questions about earth.
1. What would happen, if earth were flat?
If earth were flat disc, the center of gravity would be at the center of the disc. Men, plants, oceans and all would be attracted towards the center. Everything would slide towards the center, as if they were in saucer. Hence, the globe is the apt shape for the earth.
2. If you fall through the earth, what will happen?
You will pass through the center of gravity, you will be attracted from both the ends. You will oscillate in the tunnel. Each oscillation will take 42 minutes.
3. Suppose earth's spinning is stopped but it revolves around the sun. What are the consequences?
Earth is spinning at 1000 km per hour. If it suddenly stops, the atmosphere which is moving along with it, will at once move away into space. One day will be one year long. Six months would be duration of night and day will be six month long. Earth's magnetic field will vanish. The satellites and GPS will not work. Oceans will move to north and south poles.
4. If Himalayan like mountains erupts from the surface of the earth, what will result?
When earth slightly bulges, it moment of inertia increases. Consequently its speed of spinning will decrease a bit, according to the principle of conservation of angular momentum.
China has built a huge dam and stored ocean of waters.It is equal to slight bulging of earth. Hence earth is slowed down by the dam by a fraction of micro second. It said so.
5. If earth moves away from the sun, what will happen?
If earth moves away from the sun, we will freeze. If it moves closer, we will face the intense heat. Now the earth is at the right distance from the sun for sustaining the life.
Earth 'as it is, where it is' is good for us. The creator had well. thought out.
