SOLAR SYSTEM

Detailed explanation-1: -Earth was shaped by the effects of gravity, radioactivity, and physical disturbances like meteorite bombardment and volcanic activity. Around 3.8 billion years ago, the Earth’s mantle began to cool. An atmosphere containing oxygen began to form. And because it contained oxygen, it could sustain life.

Detailed explanation-2: -The Earth is an oblate spheroid. The shape of the Earth is affected by factors such as gravity, stress, and density.

Detailed explanation-3: -These processes-including movement in the tectonic plates in the crust, wind and water erosion, and deposition-shape features on Earth’s surface.

Detailed explanation-4: -The Earth’s shape is ellipsoid thanks to gravity hammering it throughout its lifetime like all other planets in our solar system. The ellipsoid shape is the reason why there is a greater distance between the center of Earth and the surface at the equator than the center of Earth and the surface at the poles.

Detailed explanation-5: -The Earth is almost completely round. The force of gravity would pull the Earth into a perfect sphere shape, but the fast rotation of Earth on its axis, an imaginary line running from the North Pole to the South Pole, reduces the effect of gravity on the equator.
