compaction
Sediment layers are squeezed from above by the weight of overlying sediment, causing compaction. Compaction squeezes out air and water between the sediment particles. Minerals form as the air and water is squeezed out, cementing the particles together, and forming sedimentary rock.

Weathering is the breaking down of existing rock into smaller pieces that are transported by erosion to a place of deposition, which can lead to compaction and cementation--two processes necessary in the formation of sedimentary rock.
