Environments

A. Weathering (phys. & chem.)

B. Erosion (wind, water, glaciers)

C. Deposition (deserts & bodies of water)

D. Compaction & Cementation (glue)A. Because of mineral rich ground water

A. Clastic – Made of fragments from other rocks and minerals. (sandstone, siltstone, conglomerate)

B. Chemical Evaporites – Minerals build up in bodies of water that have no outlets and as water evaporates minerals are left behind. (halite, gypsum)

C. Organic – Clastic or chemical sedimentary rocks that contain the remains of animals or plants. (coquina, limestone, coal)

Source (MTs) >>>>>>>>>>>>>Far (Ocean)

Course Medium Fine

Course – Small to large stones. Glaciers, not far

from source.

Medium – Sand sized particles.

Fine – Clay sized particles. Remove far from source.

All cave formations!

A. Clastic – Glaciers, desserts, beaches, lakes, deltas

B. Chemical evaporites – Caves, salt lakes & seas, ocean

C. Organic – Swamps, deltas, reefs, lagoons, ocean
