Question

why earth is sphere in shape$\left \{ {{y=2} \atop {x=2}} \right.$

Answer 1

When the earth started to come in form it is made by many tiny particles( for us these particles are very large) move in a circular motion these particles join to each other and form smaller bodies and these smaller bodies form more larger bodies due to their circular motion we got large spherical bodies(you can see our neighbouring galaxy make new stars and heavily body come in existence) similar to our earth but some believe that earth is the part of he sun.
If you satisfied with my answer you can mark it brainiest

Answer 2

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.

That’s because of gravity. Because 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.
