Water.
Because of gravity.
This process is called erosion. Erosion is the process of eroding or being eroded by wind, water, or other natural agents
The dominant process is erosion (generally a destructive process). Events that increase the elevation of land surfaces are either very slow (orogeny) or sporadic (volcanoes, earthquakes).

Erosion by weathering.
Water is the most dominant agent of erosion on Earth. It shapes the Earth's surface through processes such as rivers carving out valleys, waves eroding coastlines, and glaciers moving and shaping the landscape.
Erosion and weathering
Removes the surface material of the earth.
Because of gravity.
The process of sediments moving slowly downhill is called erosion. Erosion is the transportation of rock fragments and soil particles by natural forces such as water, wind, or ice. It can happen gradually over time and shapes the Earth's surface.
The force of water moving over a surface can create friction due to the contact between the water molecules and the surface, which can lead to erosion or wear of the surface over time. This process is often seen in natural settings where flowing water shapes the landscape by wearing down rocks and soil.
Erosion
Glacial erosion is caused by moving masses of ice. As glaciers flow over the land, they pick up rocks and debris, scraping and carving the land beneath them. This process shapes the landscape through processes such as plucking and abrasion.
