Detailed explanation-1: -Accretion theory explains how planets formed from the gas, dust, and ice revolving around an early sun. The dust collected into clumps and would stick together due to gravitational forces. Gravity is the force behind accretion that pulls particles of matter together.
Detailed explanation-2: -Plate tectonics is the name for the process that forms Earth’s features. Plates spread apart, bump together, slide under one another, or slide past each other. Forces on the surface also change the land. The movement of wind and water breaks rock down, and erosion wears Earth’s surface away.
Detailed explanation-3: -The earth has many major geographic features, with the most broad being the land masses known as continents and oceans that cover it.
