Will give why are all planets almost spherical in shape?   because a planet's gravity pulls equally from all sides  because large bodies in space break apart due to gravity  because gravity pulls all material towards the edge of a planet  because rotation pushes outwards the material inside the planet

Because a planet's gravity pulls equally from all sides

Step-by-step explanation:

The fundamental force responsible for the formation of a planet is gravitational force. Every body that has mass exerts gravitational force. It is an attractive force.

Planets are almost spherical in shape. This is because gravity pulls equally from all sides. In fact, bodies that orbit a star, clear their neighborhood and are round in shape are characterized as planets.
