Categories of Sedimentary Rocks
VOCABULARY
1. Clastic: made of fragments of previously
existing rocks
2. Organic: formed directly or indirectly from
plants or animals that were once living
3. Chemical: formed from large mineral deposits
13. CHAPTER HOME
KEY CONCEPT
Clastic Rocks
VOCABULARY
Clastic rocks are made of fragments of previously existing
rocks
• Divided into categories according to shape and size of
fragments
Conglomerate: 1/3 of the rock contains pebbles
Sandstone: made of sand sized grains
Shale: made of particles smaller than sand

KEY CONCEPT
Organic Rocks
VOCABULARY
Organic: formed directly or indirectly from plants or
animals that were once living
• Limestone: contains calcite and shells.
Sometimes fossils
• Chalk: fine grained limestone
• Coal: formed from remains of living things

Chemical Rocks
VOCABULARY
Chemical: formed from large mineral
deposits
• Rocks that are mined from mineral deposits that
formed by evaporation
• Examples: rock salt, gypsum

Editor's Notes
Nit-picky, but the green-gray arrow (prior to and proceeding animation) has a line btw the head and tail. Could bring the two portions together so there is no line? (I can’t figure out how to get down to that arrow…)
