IGNEOUS

Forms when molten lava (magma) cools and become solid rock. The word "igneous" comes from Latin - meaning “fire”

(think of "igniting" something)

Wind and Rain cause rock to break down into sand, soil and minerals. Erosion carries small particles of sediment until it gets "deposited".

SEDIMENTARY

As layers of rock and sediment pile up, the weight puts great pressure on rocks down below. That plus, heat from magma under the crust causes rock to "morph" into more dense rock.

METAMORPHIC

Under enough heat and pressure, rock will eventually melt back into Magma and begin the rock cycle over again.

Melting

Metamorphic: to “morph” = changing

● Formed from other rocks under heat and pressure

● Generally stronger, more compact rock

● Often has folded/wrinkled lines = “foliated”

Crystals form as lava cools...

the SLOWER it cools, the LARGER the crystals!

The cooling rate (how fast or slow) determines the texture of igneous rock.

compacting

Root word “sediment” = small particles (like sand)

  • ●Goes through compacting & cementing (like glue)

  • ● Usually has layers (horizontal lines) from “deposition” (deposits)

  • ● Fossils are only found in Sedimentary Rock
