metamorphosis
No, but they can be changed by natural process acting on them.
It can be changed by being broken down in the weathering process just like all rocks. The resulting sediment can then be lithified to for a sedimentary rock.
Metamorphism is the process where existing rocks are changed by heat, pressure, or fluids. This process causes the minerals in the rocks to rearrange and form new crystals, creating metamorphic rocks.
Increase the pressure and temperature by burying them; or heat them with an igneous intrusion.
This process is called metamorphism and it creates metamorphic rocks, such as marble.

Changed rocks are called metamorphic. Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, through the use of heat and pressure.Metamorphic rocks
Sandstone is changed into quartzite and basalt is changed into schist or gneiss through the process of metamorphism.
Sedimentary rocks can be changed into metamorphic rocks through heat and pressure, while igneous rocks can be changed into metamorphic rocks through the same process. Both types of rocks can also be weathered and eroded, leading to the formation of new sedimentary rocks.
