graded beds; a change in water flow speed

cross beds; water or wind flow

horizontal laminations; low energy environment

tilted beds; large-scale tectonic processes

Includes only three types of sedimentary rocks: clastic, organic chemical, and biochemical. 

Chemical sedimentary rocks are classified primarily on the basis of mineral composition.

Clastic sedimentary rocks are classified primarily on the basis of grain size.

Are most likely to preserve conditions of ancient environments.

Are most likely to form at or near Earth's surface.

fining of sediment (clast size decrease)

coarsening of sediment (clast size increase)

no change in clast size

diagenesis

transport

weathering

lithification

erosion

was formed in a deep ocean

was a result of a change in water flow speed

was once covered by glaciers

was once covered in wet mud
