magnets
It moves by different rocks and soils are carried from the water and is buried under bigger holes and rocks.
The force of moving water alone can wear away particles of rock.
weathered remains of other rocks
The force is created by the self weight of the overlying material.
When older rocks, plants, and other loose material get pressed or cemented together
the material which smaller rocks and other minerals come from.
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.
It is Aluminium.
Because rocks are formed deep in the Earth, and sometimes by compressed sand other sedimentary material.
A vein in a rock is some other material than the surrounding rock.
It can provide materials to make other rocks, also form other rocks and be changed by the force of the earth
