Sedimentary Rocks

How are sedimentary rocks formed?

• Sedimentary rocks are formed by volcanic activity.

• Sedimentary rocks are created by metamorphism.

• Sedimentary rocks are formed through the process of weathering, erosion, deposition, compaction, and cementation.

• Sedimentary rocks are a result of tectonic plate movement.
