• Igneous Rocks are tested by streak test, texture ,and if you can see minerals.

• Porphyritic, pegmatitic, and vesicular are all types of igneous rocks.

Metamorphic Rocks!

• Metamorphic rocks are rocks that have "morphed" into another kind of rock.

• Metamorphic rocks are tested by streak test, texture ,and if you can see minerals.

• Limestone , sandstone ,and fine grained rocks are all types of metamorphic rocks .

Sedimentary Rocks!

• For thousands, even millions of years, little pieces of our earth have been eroded--broken down and worn awayby wind and water.

• Sedimentary rocks are tested by streak test, texture ,and if you can see minerals.

• Iron ore, coal, and shale rocks are all types of Sedimentary rocks.
