Water that causes erosion picks up sediment, rocks, and organic material as it moves downstream. This material can range from tiny particles like silt and clay to larger rocks and boulders, depending on the force of the water and the terrain it is flowing through.
The force of moving water alone can wear away particles of rock.
weathered remains of other rocks
The material deposited on the edge of a glacier is called moraine. This debris consists of rocks, soil, and other materials that the glacier has picked up as it moves, forming ridges or mounds at the glacier's terminus.
When older rocks, plants, and other loose material get pressed or cemented together
Gravity is the force that causes rocks or soil to move downhill. As material accumulates on a slope, the force of gravity pulls it downward due to the angle of the slope. This movement can lead to landslides or rockfalls.
Gravity is the force that pulls rocks and soil downslope. The steeper the slope, the greater the force of gravity acting on the material, causing it to move.
This is caused by erosion.Erosion is a gravity driven process that moves solids (sediment, soil, rock and other particles) in the natural environment or their source and deposits them elsewhere. It usually occurs due to transport by wind, water, or ice; by down-slope creep of soil and other material under the force of gravity; or by living organisms, such as burrowing animals, in the case of bioerosion.
Because rocks are formed deep in the Earth, and sometimes by compressed sand other sedimentary material.
Gravity is the primary force that causes rocks and dirt to move downhill in a landslide. Wind can contribute to the movement of loose material, but gravity is the dominant force in causing landslides.
A vein in a rock is some other material than the surrounding rock.
