How does sediment become sedimentary rock?

• Sediment deposits in one place and settles in layers. The weight of the sediment squeezes the layers together.

• Sediment deposits in one place and mixes together. Then wind, weather, and ice freeze the mixture into rock.

• Sediment settles on limestone cliffs and inside caves. There, it forms minerals and turns into rock.

• Sediment mixes with seashells and fossils. Then wind, weather, and ice erode the mixture into sedimentary rock

What does "metamorphic" mean?

• grainy and porous

• changing in form

• having layers

• full of colors

How does metamorphic rock form?

• Heat and pressure inside the Earth changes existing rock into new different rock.

• Sediment layers on top of itself, and gravity and pressure turn it into new rock.

• Magma deep below the Earth's surface hardens into metamorphic rock.

• Wind, rain, and other weather turn lava from volcanoes into metamorphic rock.
