OUR planet is in a sphere shape WHY?

Answer 1

Technical Answer -

All of the planets are round because of gravity. When our solar system was forming, gravity gathered billions of pieces of gas and dust into clumps which grew larger and larger to become the planets. The force of the collision of these pieces caused the newly forming planets to become hot and molten. The force of gravity, pulled this molten material inwards towards the planet's center into the shape of a sphere. Later, when the planets cooled, they stayed spherical. Planets are not perfectly spherical because they also spin. The spinning force acts against gravity and causes many planets to bulge out more around their equators.


Dummies Answer -
Its a bit like rubbing playdoh into a ball in your hand if the force is equal it will eventually become spherical shaped.

Answer 2

Our planet is in the shape of sphere because if it is in any other shape it cannot revolve round the sun in a circular manner

Answer 3

The tangential force along it's equator throws the mass outwards when it rotates along it's axis.Say,if you try spinning a ballon full of fluid,it too might take the spherical shape due the same reason,although there is no comparison between the ballon and earth,the example is just to try to explain why.

Answer 4

round is the best shape to hold things
