Sedimentary rocks form by the precipitation of inorganic material from lakes or shallow seas.

• Geologic

• Chemical Precipitate

• Erosion

• Sedimentary

Slower rate of cooling causes this; Larger crystalline grains.

• Fine Grain

• Sediments

• Coarse Grain

• Weathering

The process that presses/ squeezes sediments together.

• Compaction

• Pressure

• Molten

• Chemical Precipitate

Washing rock away by wind or water from one location to another.

• Water

• Weathering

• Breaking

• Erosion

Indicates magma that rapidly cooled at or near the Earth's surface. Individual minerals are relatively small.

• Fine Grain

• Coarse Grain

• Salt

Repetitive layering of rocks in metamorphic rocks.

• Foliated

• Cementing

The long period of time occupied by the earth's geologic history.
