• an igneous intrusive rock

• a sedimentary rock

• an igneous extrusive rock

• a metamorphic rock

All of the following are characteristics of metamorphic rocks except ---

• holes from trapped gases

• flattened crystals

• colored, parallel layers

• bending from pressure

Of these igneous rocks, which would contain the largest crystals?

• Rhyolite

• Pumice

• Obsidian

• Granite

Which of these provides the best evidence of the environment in which an igneous rock was formed?

• Texture

• Thickness

• Color

• Size

In the illustration shown, which layer is an example of an intrusion?

• 4

• 2

• 3

• 1

Extrusive rocks have small grains because they ---

• cool quickly

• harden underground

• contain rare minerals

• have a rough mixture

Rocks formed by the cementing of weathered materials are called ---

• sedimentary rocks

• magma

• extrusive igneous rocks

• basalt

Metamorphic rocks with a layered or banded look are called ---

• unfoliated

• evaporated

• striated

• foliated

Obsidian, pumice, and scoria lack crystals because ---

• they cooled too quickly

• they cooled too slowly

• not enough minerals were present where they formed

• they cooled deep inside Earth

Which of the following processes will change a sedimentary rock into an igneous rock?

• Faulting and fracturing

• Deformation and deposition

• Erosion and deposition

• Melting and crystallization
