Why is the earth round?

Answer by  tamarawilhite (17883)

Mass naturally seeks the surface with the lowest surface area, which is a sphere. The Earth is round because gravity pulls it into a sphere, which is the shape with the lowest surface area. The variations in the Earth's surface are due to recent thrusts up by plate tectonics.

The earth isn't perfectly round, but it has a spherical shape because of gravity, which pulls equally at the earth in all directions, giving it a round shape.

The earth and other planets formed when molten rocks and other materials in space came together. Gravitational forces caused them to revolve around the sun as well as spinning on their axis, producing a round shape.
