Basically physical and chemical weathering (do not confuse with erosion, which involves movement) contribute to the destruction of mineral forms. In this case it breaks down the rocks, minerals and soils, creating slopes and hills. It may be caused by (any form of) water, wind, gravity, waves or sunlight.

A solar system is a group of planets that orbit around a sun (giant burning star) that has enough gravity to keep the planets from crashing into each other, as well as stop them from drifting away
