THE ROCK CYCLE
First, let's see how IGNEOUS rocks are made.
Melted rock is called Magma
When magma hardens, it makes Igneous rocks.
Most Igneous rocks form underground.
Some Igneous rocks form when volcanoes erupt!
Not all rocks are Igneous.
There's one more way rocks are made.
This process creates SEDIMENTARY rocks.
These changes are a cycle!
(They happen over and over.)

It can go the other way too!

In fact, the Rock Cycle never ends! A rock is constantly in the process of changing. It can take a million years for one rock to change into another one.
Basalt
Pumice
Examples of Igneous Rocks:
Granite
Obsidian
Some rocks are smashed and baked, but not melted.
These rocks are called
METAMORPHIC.
After thousands of years, the intense heat and pressure makes new rocks.
Examples of Metamorphic Rocks:
Quartzite
Gneiss
Marble
Slate
Schist
Water breaks big rocks into little rocks.
Little rocks break into peices of sand.
Conglomerate
Examples of Sedimentary Rocks:
Over thousands of years the grains of sand get cemented together and form brand new rocks.
Limestone
Shale
Sandstone
