THE ROCK CYCLEHow are all rocks interconnected?

Learning Targets• Be able to read and follow the rock cycle• Be able to fill in and describe the rock cycle diagram

Lets start with magmaWhat happens when magma/

lava cools?◦Forms igneous rocks

Now lets break the rock downWhat is this process called

◦Weathering

What are pieces of broken rock called?◦Sediments

What is the process of making sedimentary rocks called?◦Lithification

Lets bury the rockWhat type of rock will form if

great heat and pressure are applied?◦Metamorphic

Lets get back to magmaHow do we get back?

◦Melt the rock

How can we simplify this?We use a simple diagram called

the ROCK CYCLEWhat do you think of when you

hear the word “CYCLE”?◦Bi/ Tricycle?◦Water Cycle?◦Circles!?
