3) How do convection affect the Earth?

5. Objective SWBAT explain the rock cycle and what powers it
SWBAT explain the different parts of the rock cycle; weathering & erosion specifically

6. Today’s Exit Ticket
How do we classify rocks as either igneous, sedimentary, or metamorphic?
In which type of rock does bedding normally occur?
Explain what bedding is.
Metamorphic rocks are formed through high levels of heat deep within the ground. Where does this heat come from?
Imagine that you are near a volcano. Which type of rock can you expect to find? Why?
John has a metamorphic rock and Aaron wants a sedimentary rock. What must happen to John’s metamorphic rock before it becomes a sedimentary rock?

7. Rocks A rock is a group of minerals bound together
The three types of rock are Igneous, Sedimentary, and Metamorphic Rock

9. Rock Cycle*
The Rock cycle demonstrates the relationships among the 3 major rock groups (Sedimentary, Igneous, and Metamorphic)
It is powered by:
the internal heat of the Earth
the energy from the SUN
It involves processes on the Earth’s surface as well as the Earth’s interior

11. Igneous Rock Igneous- Comes from the Latin word ‘ignis’ meaning fire
Formation
When magma hardens or lava cools.
Destruction
Weathering and Erosion - the removal of rock due to wind, water, ice or gravity.

12. Igneous Rocks Hints that you are seeing an igneous rock: Bubbles
Glassy appearance
Big grains of minerals

13. Bubbles

14. Glassy Appearance

15. Big Grains

16. Sedimentary Rock
Sedimentary- Comes from the Latin word ‘sedimentum’ meaning settling.
Formation
Sediment from weathering and erosion is deposited and then rock is formed from cementation.
Destruction
Under high pressure and heat

17. Sedimentary Rocks Hints that you are seeing a sedimentary rock:
Flat layers
Mix of particle size
Sedimentary rocks create a process called BEDDING. BEDDING occurs when large amounts of sediment are deposited and turn into large rock formations

18. Flat Layers

19. Mix of particle size

20. Metamorphic Rock Metamorphic- Comes from the Greek word
‘meta’ meaning to change
Metamorphic rocks change due to heat & pressure
Formation
Rocks are changed by heat or pressure. This is often when how magma is introduced to a body of rock.
Destruction
Metamorphic rocks are destroyed when they are heated up as magma.

21. Metamorphic rocks Hints that you are seeing a metamorphic rock:
Bending layers
Squished Grains
Layers in metamorphic rock are called FOLIATION

22. Bending LAyers

23. Squished Grains

24. Test yourself
try to identify the correct type of rock for each of the following pictures

25. Sample 1

26. Sample 2

27. Sample 3

28. Answers Sedimentary (mix of particle size) Igneous (bubbles)
Metamorphic (bending layers)

WHAT
OF ROCK?
This rock was formed by the compaction and cementation of sediment

31. WHAT
OF ROCK?
TYPE
This rock was formed by melting and cooling of magma.

32. WHAT
OF ROCK?
TYPE
This rock was formed by heat and pressure deep within the Earth.

35. WHAT
OF ROCK?
TYPE
This type of rock is found near volcanos.

36. WHAT
OF ROCK?
TYPE
This type of rock is found deep within the Earth.

37. WHAT
OF ROCK?
TYPE
This type of rock is much like our ice cream, it starts as a liquid and then cools into a solid.

38. WHAT
OF ROCK?
TYPE
This type of rock is much like our sandwich. It is made of many layers stacked on top of each other.

39. WHAT
OF ROCK?
TYPE
This type of rock is like our cake. It is baked but not melted.

40. WHAT
OF ROCK?
TYPE
Conglomerate is an example of this type of rock.

41. WHAT
OF ROCK?
TYPE
This type of rock can be intrusive or extrusive.

42. WHAT
OF ROCK?
TYPE
This type of rock can be clastic or chemical.
