by weathering
Any and all rock can be changed into sediment by weathering and erosion.
Weathering can happen to any rock. It is the first stage in the process that leads to the formation of sedimentary rock.
Weathering is weathering, no matter how it occurs. Both chemical and biological weathering wear down rock. They simply go about it in different ways.
Erosion of igneous and metamorphic rock
Erosion it also means abrasion, which does with weathering
This is called erosion.
The two main types of weathering are physical weathering and chemical weathering. Physical weathering involves water, wind and dust scraping away at rocks, while chemical weathering involves chemicals, usually acids, breaking down the rock.
frost wedging
Erosion is the removal of the topsoil either by water or wind, while weathering is the break down of rock to form soil.
The process of removing rock particles by wind, water or ice is called erosion. This can also be the removal of enamel from teeth by acid (acid erosion). To be more precise, this is weathering process of the rock where in the rock is broken into small particles by natural forces like wind, water, ice or gravity to get it eroded.
When a mass of rock is exposed by weathering and by removal of the overlying rock there is a decrease in the confining pressure on the rock, and a slight expansion of the rock volume. This unloading promotes cracking of the rock – known as exfoliation - and the development of cracks leads to other kinds of weathering.
That would be mechanical weathering
