1. Welcome to Science 11/3
Get out your Rock Outline/Chart that you began yesterday. Answer questions 1-4 on your own.
Turn in any late HWs from yesterday.
Today’s Schedule
1. Question of the Day
2. Continue Discussion on Rocks

2. Question of the Day This is a 2 part question.
1. What type of rock makes up 90% of Earth’s crust?
Igneous rock
If igneous rock makes up 90% of Earth’s crust how did other rocks form to make the remaining 10% of Earth’s crust?
Weathering & erosion helped make new types of rock as well as processes like EQs and subduction.

3. Igneous Rocks
What do you know?

4. Igneous Rocks Igneous come from the latin word ignis, meaning “fire”
90 % of Earth’s crust is made of igneous rock. So, what are igneous rocks made from?
Magma and lava

5. Igneous Rocks
If igneous rocks form from magma and lava, where can igneous rocks form?
On the surface = extrusive rock
Below the surface = intrusive rock

6. Granite
Gneiss

7. Sandstone
Quartzite

8. Shale
Slate

9. Welcome to Science 1/4 Take your HW out and also take your notes out.
Today’s Schedule
1. Video of the Day
2. Challenger Mission
3. Go over HW
4. Metamorphic Rocks
5. HW Assignment

10. Mighty Metamorphic Rocks
What does metamorphic mean?
Dynamic Change

11. What does it take to morph rock?
When heat & pressure from
Deep inside Earth change
a rocks minerals, it becomes
a metamorphic rock.

12. How do rocks get deep inside Earth or how does heat come to the surface?
Subduction
Converging plates
Rising magma

13. Venn Diagram Tips: Classification Composition Origin Uses Formation
Directions: Each circle represents 1 of the 3 groups of rocks. In each circle write information about that group of rock. If groups of rock of something in common, write the info in the area where the circles overlap. You need to have at least 5 facts for each group of rock and at least 5 facts that are shared by the groups of rock.
