1. SEDIMENTARY ROCKS

2. What is a sedimentary rock?
Sedimentary rocks are rocks that have formed from minerals in solution crystallizing, from fragments of other rocks, or from organic processes

3. What are the 3 types of sedimentary rocks?
Clastic
Chemical
Organic

4. What are clastic rocks?
Clastic rocks contain sediments that are cemented together with minerals

6. How do clastic rocks form?
Rocks must be broken down into small fragments
This happens when preexisting rocks are weathered
Fragments may be pebbles, gravels, sand, silt, clay or fossils

7. Cementation
These sediments become cemented together, usually with dissolved minerals
The minerals crystallize, locking the grains together

8. Cementation Process
Over time, sediments are buried and compacted. After dewatering, minerals form a cement-like mixture

9. What is chemical rock?
Chemical sediments form when minerals precipitate out of solution
Common chemical sedimentary rocks are:
-Rock salt
-Gypsum
-Limestone

10. What is organic rock?
Organic rock consists of the remains of plants and animals
