Why does the earth have a sphere shape?

The Earth has a spherical shape primarily due to gravity, which pulls matter toward the center of mass, resulting in a shape that minimizes gravitational potential energy. During its formation, the Earth was molten, allowing it to settle into a rounded shape as it cooled. Additionally, a sphere allows for an even distribution of gravitational forces, contributing to stability in planetary bodies. This shape is also a consequence of the balance between gravitational forces and the centrifugal forces arising from the planet's rotation.
