Igneous rocks are classified by ___________. Rocks that ___________ are called intrusive rocks, and rocks that ___________ are called extrusive rocks.

• how fast they cool; cool slowly; cool quickly

• how hot they get; are hotter; are cooler

• how large they are; are larger; are smaller

• how dense they are; are denser; are less dense

How is rock formed through physical sedimentation?

• Magma is deposited on the Earth’s surface where it hardens.

• Water dissolves sediment for later crystallization or use by organisms.

• Sediment is moved continuously by the elements, collecting more rock as it moves.

• Rock is broken down by the elements into tiny fragments that are later deposited and compacted together.

Fine-grained sediment is more likely found on ________ slopes, and coarse-grained sediment is more likely found on __________ slopes.

• wetter; drier

• gentler; steeper

• shadier; sunnier

• grassier; tree-covered
