U2L4 The Rock Cycle

Igneous rock is made by ___________.

• cooling magma either on or below the surface.

• erosion and sedimentation of existing rocks.

• metamorphism of existing rock under heat and pressure.

• deposition of organic material over time.

You are analyzing a rock made of small rock fragments and the remains of plants and animals. What type of rock are you analyzing?

• igneous

• volcanic

• sedimentary

• metamorphic

What type of rock undergoes a transformation through high heat and pressure?

• igneous

• volcanic

• sedimentary

• metamorphic

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

• their mineral composition; form underground; form on the surface

• their color; are dark; are light

• their texture; are coarse-grained; are fine-grained

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.
