Sedimentary Rocks

the effects of freezing and thawing, plant roots, acid, and other forces on rock

• deposition

• erosion

• weathering

• compaction

the process by which running water, wind, or ice carry away bit of broken-up rock.

• deposition

• erosion

• weathering

• compaction

the process by which sediment settles out of the water or wind carrying it.

• deposition

• erosion

• weathering

• compaction

the process in which sediment presses together.

• deposition

• erosion

• weathering

• compaction

dissolved minerals crystalize and glue particles of sediment together

• deposition

• erosion

• cementation

• compaction

Select the correct order for the process

• compaction, depostion, weathering and erosion

• weathering and erosion, cementation and depostion

• weathering and erosion, deposition, compaction, cementation

• cementation, weathering and erosion, compaction, depostion

Ther are three major types of sedimentary rocks, choose the type that is not one of those.

• chemical

• crystal

• organic

• clastic

formed when rock fragment are squeezed together. They are grouped by size of the rock fragments. Shale, sandstone and breccia are common ones.

• chemical

• crystal

• organic

• clastic

made from the remains of plants and animals

Ÿ limestone - made from coral reefs and other organic marine materials

Ÿ chalk - cemented grains of tiny sea creatures

Ÿ coal - decayed plants

• chemical

• crystal

• organic

• clastic

formed when minerals precipitate (come out of solution) or are left behind during evaporation

Ÿ halite - rock salt created from salt water

Ÿ limestone - made from tiny grains of precipitated minerals

Ÿ geodes - water with dissolved minerals filled a hollow; as the water evaporated, minerals crystallized and remained behind
