Rocks Review

What are the three different forms of rock?

• Intrusive, Chemical, Foliated

• Limestone, Sandstone, Obsidian

• Mineral, Rock

• Sedimentary, Igneous, Metamorphic

Which is a type of intrusive igneous rock that bears a lot of weight, resists scratching, and is often used for countertops?

• Limestone

• Pumice

• Granite

Which type of sedimentary contains fossils in its layers?

• Clastic

• Chemical

• Biochemical

Why do some say coal is a sedimentary rock?

• Because heat and pressure change peat into coal.

• Because a volcano forms coal.

• Because layers of peat compact to form coal.

This type of rock is formed when molten material cools are crystallizes.

• Metaphoric

• Sedimentary

• Igneous

Intrusive igneous rocks have which of the following classifications

• Formed inside a volcano

• Small crystals

• Cools slowly

• Smooth texture

Extrusive igneous rocks have the following characteristics:

• Forms outside a volcano

• Small crystals

• Cools quickly

• Smooth texture

Which of the following is the correct order of the steps of sedimentary rock formation?

• Weathering, deposition, erosion, compaction and cementation

• Erosion, weathering, deposition, compaction and cementation

• Weathering, erosion, deposition, compaction, cementation

• Cementation, erosion, deposition, weathering, compaction

If a grains are rounded, large, and not well sorted it means:

• It traveled far distance, slowly, in a glacier.

• It traveled a short distance, fast, in wind.

• It traveled a short distance, slowly, in a glacier.

• It traveled a far distance, fast, in a glacier.

What form of rock forms when water evaporates and the minerals are deposited out of the water?

• Chemical Sedimentary Rock

• Clastic Sedimentary Rock
