Rocks and Minerals

Igneous Rock

• Can you remember what igneous rocks are made from?

• That’s right!! Igneous rocks are made from lava or magma that has been cooled and hardened into a rock.

Sedimentary Rock

• Sedimentary rock is made from what?

• Correct!! It is made from sediment (this one should be easy to remember!!). Sediment is tiny little pieces of rock that is smashed together really hard for a really long time. It eventually becomes a rock!

Metamorphic Rock• Can you think of a time where you have

heard a word like Metamorphic?

• If you said when a butterfly changes, you are correct (metamorphosis)

• The idea is that when a rock changes, it also metamorphoses into a different rock!

•A metamorphic rock could become an igneous, a

sedimentary, or another metamorphic rock. It all

depends on what happens to the rock!!!

The Rock Cycle

• The rock cycle is the idea that all rocks can become all other types of rocks by adding heat and/or pressure!

Just think of it like this!!!• Rock Cycle Song

(Sing to the tune of "Row, Row, Row Your Boat") • SEDIMENTARY rock

Has been formed in layers Often found near water sources With fossils from decayers

• Then there's IGNEOUS rock Here since Earth was born Molten Lava, cooled and hardened That's how it is formed

• These two types of rocks Can also be transformed With pressure, heat and chemicals METAMORPHIC they'll become.

Can you classify these rocks???

• Classify each of the rocks as igneous, sedimentary, or metamorphic. Discuss with your neighbor. We will decide as a group what we believe each picture is!
