falling in water
this causes erosion
it can fall down the hill or get buried.
it doesn't do that bad because it also carries the sediments that weathering breaks down so it also builds the Earth up
Sedimentary rocks are formed by layers of sediments that build up over along period of time. The rocks are being mixed and compressed together for extended periods of time.
By weathering rock and carrying it away to different places. That process is called erosion. Then it deposits the sediments and builds, which is called deposition.

It builds up in preparation to receive a fertilized egg and allow it to imbed and begin to grow.

Sediments (sand, clay, boulders etc) are derived from the erosion of preexisting rocks by snow, ice, water and wind. Eventually these sediments settle and are covered by more sediments. As the weight of overlying sediments builds up the pressure and minerals dissolved in and carried by groundwater cement the sediment particles together to form a new rock layer. This new rock is called a sedimentary rock.
a process in which a force builds up landmasses on the surface of the Earth
photosynthesis
The process is called metabolism.
