Rocks can be categorized into three main types - igneous, metamorphic, and sedimentary. Igneous rocks form from cooled magma or lava. Metamorphic rocks were once sedimentary or igneous rocks but have been changed by pressure or heat. Sedimentary rocks form through the compaction of sediments and include sandstone, shale, and limestone. The document provides a basic overview of the three rock types and how they are formed.

2. EQ: what are rocks?
• A rock is a nonliving thing that is made up of
minerals. There are hundreds of different
types of rocks.

3. Igneous rocks
An igneous rock is often called fire rock . it is
made of cooled magma, or cooled lava. They
can also be formed when lava gets trapped
underground. Basalt and granite are 2 types of
igneous rocks.

4. Metamorphic rock
• Metamorphic rocks are rocks that have
changed. These rocks were once sedimentary
or igneous rocks, but have been changed be
pressure or heat. Any rock can become a
metamorphic rock.

5. Sedimentary rocks
• Sedimentary rocks are called layered rocks.
Sedimentary rocks form when weathered and
eroded materials are dropped off from the
earth and into oceans, rivers and lakes.
Sediment is pressed down into the layer and
forms the rock. 3 types are sandstone, shale,
and limestone.
