Which type of rock is formed from limestone that has been compacted, heated, and recrystallized?

• siltstone

• sandstone

• marble

• shale

Which statement best describes the formation of an intrusive igneous rock?

• Magma solidifies slowly, resulting in a coarse-grained texture

• Magma solidifies slowly, resulting in a fine-grained texture

• Magma solidifies rapidly, resulting in a glassy texture

• Magma solidifies rapidly, resulting in a clastic texture

Large mineral crystals in a rock indicate that

• Cooling lava was present.

• It was formed in a confined space.

• There was a relatively long cooling period.

Deposits of halite, or table salt, have formed over millions of years in locations where ancient seas were once present.
This means that minerals ________

• Can only form beneath the surface.

• Can form through evaporation of solutions.

• Form only when hot water solutions are underground and rise to the surface.

• Usually take a very long time to form.

The rock cycle shows how rocks change through weathering, erosion, and melting.
Why does the rock cycle provide evidence for the law of conservation of matter?

• The total amount of rock material stays the same, even though its form changes.

• New elements are constantly created during rock transformations.

• The rock cycle uses up large amounts of energy over time.

• The rock cycle only works for certain types of rocks.
