2. The Rock Cycle
Key Question: What are the processes rocks undergo in the rock cycle?
Key Words:
Weathering / erosion
Deposition
Burial
Compaction & Cementation
Lithification

3. Listening Task Listen to the story and draw out a
diagram of the rock cycle in pairs on
your mini whiteboard

4. Toastie Rock Cycle What are the stages in making a tostie?
How can they be
used to show the stages in the rock cycle?

5. Stage 1 Grate the cheese This represents…. WEATHERING
White = Granite and Yellow = Basalt

6. Stage 2
Move the cheese
This represents….
Erosion

7. Stage 3 Lay down the bread on the tostie maker This represents……..
Original layers of sedimentary rock in the oceans

8. Stage 4
Add a slice of Ham
This represents……..
DEPOSITION OF SHALE

9. Stage 5 Add two cheeses This represents…….. DEPOSITION OF SANDSTONE
LAYERS

10. Stage 6 Add the top slice and give it all a press down
This represents……..
COMPACTION, CEMENTATION and BURRIAL

11. Stage 7 Turn on the toastie maker and press down This represents……..
INCREASING HEAT AND PRESSURE

12. Stage 8 Leave for a few mins This represents……..
METAMORPHISM (Recrystallisation)

13. Stage 9 Leave for a few mins more This represents……..
Melting and magma formation

14. Stage 10 Cheese that sticks on represents…
and cheese that spills out? ………….

15. Stage 11 Lifting out and eating This represents……..
Uplift and further weathering and erosion

16. In Pairs Construct a diagram of the rock cycle using the cards
Add arrows to the A3 paper

17. Once Checked
Make a neat copy for your book
