True or False: The Earth's Crust is Always Changing

• True

• False

Rock that comes from a magma or lava source?

• Igneous

• Metamorphic

• Sedimentary

Preexisting rock that is/was altered by extreme heat, pressure, or both.

• Igneous

• Metamorphic

• Sedimentary

Rocks that form from the weathering and erosion of sediments, which are cemented and compacted in new locations.

• Igneous

• Metamorphic

• Sedimentary

Igneous extrusive means the rock formed from a _________, ________

• magma

• lava

• underground

• on the surface

Igneous intrusive means the rock formed from a _________, __________.

• magma

• lava

• on the surface

• underground

The processes that break down prexisting rock near or on the Earth's surface.

• cementation

• compaction

• erosion

• weathering

When sediment gets carried away by wind, water, ice, gravity we call this....

• weathering

• erosion

• cementation

• compaction

Match the following

• Erosion

• How sediment gets carried to a new location, water, glaciers, wind, and gravity.

• Weathering

• pieces of weathered particles: clay, silt, sand, cobbles, and boulders.

• Sediment

• Processes which break down rock physically and chemically.

If this magma cools and solidifies underground, it will become

• intrusive igneous

• extrusive igneous

• sedimentary

• metamorphic
