why earth is round?
Answers
Explanation:
The Earth is massive enough that the pull of gravity maintains its roughly spherical shape. Most of its deviation from spherical stems from the centrifugal force caused by rotation around its north-south axis. This force deforms the sphere into an oblate ellipsoid.
so earth is round in shape .
Answer:
Thank you for your great question. Asking questions like this is really important part of being a scientist.
Imagine the Earth pulling everything it is made up of, all of its mass, towards its centre. This happens evenly all over the Earth, causing it to take on a round shape. Let me explain what I mean by that.
To understand why the Earth is round we need to look at two things - mass and gravity.
Every single thing in the universe has mass - from the biggest star to a tiny grain of sand. People, too, have mass. The more big and dense something is, the more mass it has. So an elephant would have more mass than a mouse.
While you might not be able to see it, all objects with mass are actually being pulled towards each other by a force called gravity. The bigger the mass of something, the stronger its pull.
The mass of the Earth is so much bigger than the mass of people (or spoons, or vases, or water), we’re all strongly pulled towards it, which is why it feels like we’re stuck to the earth’s surface.
Part of what makes a planet a planet is its round shape. But most things in space are not perfectly round at all!
