Loose materials such as rock fragments, mineral grains, and the remains of once-living pants and animals.

• Rock

• Igneous Rock

• Sediments

• Sedimentary Rock

The process that forms sedimentary rocks when layers of sediments are compressed by the weight of the layers above them.

• Cementation

• Compaction

• Deposition

• Erosion

The laying down, or placement, of weathered and eroded materials.

• Deposition
