Answer each question.

There are three kinds

of rocks:

METAMORPHIC

IGNEOUS

and

SEDIMENTARY.

1 - 2 - 3

Metamorphic rocks are squished and folded.

Metamorphic means to change form.

Metamorphic rocks change because of heat and pressure.

Any type of rock can become a metamorphic rock.

When rocks are buried deep in the Earth there is lots of

heat and pressure.The heat and pressure make

the rock change form.

The word METAMORPHIC

means

“to change form.”

If there is too much heat the rock will melt and become

molten magma.

Igneous rocks are formed when hot molten magma or lava cools and becomes a

solid.

The word IGNEOUS means “fire.”

Volcanic rocks are igneous rocks that formed when lava

erupted from a volcano.

Sedimentary rocks are made by the slow hardening of

tiny bits of rock, or sediment, into layers.

Sedimentary rocks are in

stripes or layers.

The Grand Canyon is sedimentary rock.

The chalk you use on the chalkboard is made of

sedimentary rock.

Rocks are always changing. This is called the rock cycle.

The Rock Cycle

Tiny bits of sediment drift into the sea.

Layers are formed and harden into

SEDIMENTARY ROCK.

Pressure and heat build up and push the rocks together

making the rocks change form and change

their name to

METAMORPHIC ROCK.

When sedimentary rock or metamorphic rock get too

hot they melt

and make

IGNEOUS ROCK.
