Which sedimentary rock may have both a chemical origin and an organic origin?

• limestone

• rock gypsum

• rock salt

• shale

The classification of rocks into sedimentary or nonsedimentary groups is based primarily on the rocks'

• origin

• density

• color

• age

A rock is composed of several large, rounded pebbles and sand grains cemented together. Which inference about the rock is best supported by this description?

• The rock is older than the pebbles.

• The rock is igneous.

• The rock is sedimentary.

• The rock resulted from evaporation of seawater.

The siltstone layer containing the dinosaur footprints was turned into rock by (a)  

• folding and faulting
• burial and cementation
• weathering and erosion
• deformation and melting
