Explanation: Weathering, both mechanical and chemical, breaks down rocks into sediments. Sedimentary rocks are the product of weathering but that does not mean they cannot be weathered down themselves. Sedimentary rocks on the surface are susceptible to weathering just as metamorphic and igneous rocks are.

What role does weathering play in the formation of sedimentary rocks?

Erosion and weathering transform boulders and even mountains into sediments, such as sand or mud. Dissolution is a form of weathering—chemical weathering. With this process, water that is slightly acidic slowly wears away stone. These three processes create the raw materials for new, sedimentary rocks.

Can sedimentary rocks be weathered?

Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock. The latter two steps are called lithification.
