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, for example.
More mass means more gravity
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.
Have you ever wondered why if you drop something, it falls towards the Earth and not up into the sky? Or the reason why we’re all stuck to the ground?
