Look at the Grand Canyon. The Colorado River has eroded the rock (as it has risen due to other geological forces).
you see here, water from the rain and wind can erode and weather away a part of land, creating a valley

Weathering and erosion.
weathering and erosion the glacier used abrasion and then all of the rocks would be taken away by erosion
first the weathering happens which causes an erosion which makes deposition.
Erosion is formed by weathering which then forms caves, meandering rivers, valleys and waterfalls.

Yes, they are.
The Grand Canyon.
Sedimentary rock is the rock formed as a result of deposits from weathering and erosion. Sedimentary rock can be millions of years old.
In cross-section: A 'U' shaped valley is formed from glacial erosion. A 'V' shaped valley is formed by river erosion.

Most canyons were formed by a process of long-time erosion from a plateau or table-land level. The cliffs form because harder rock strata that are resistant to erosion and weathering remain exposed on the valley walls.
Any type of rock that is at or near the surface could be affected by weathering and erosion. Mountains are eventually flattened; caves are formed underground. Both are the result of weathering and erosion.
