Describe how gravity affects the erosion of Earth's surface in mass movement, running water, and glaciers.

The Earth's gravity effects the erosion on it's surface with it's pulling force that pulls everything towards it's center, thus causing everything to fall and move from the higher parts towards the lower ones on the surface. When there's mass movement, the gravitation pulls it downwards, so huge amounts of ground, buildings, plants, animals, rocks fall and move to a certain lower place, thus stripping one place but filling another with lot of material of all sorts. The rivers always move downwards because of the gravitational pulling force, because of their movement they are able to pull lots of things with them, so everything they carry with them, they carry it in the lower parts and make depositions on the places were they are very slow or where they end. The glaciers are moving slow, Because of the gravitation that movement is downwards. Since they are very heavy and solid, they break the rocks with the pressure they cause on them, so they pull of that material to the lower places were they melt.
