1. Layers of the Earth and Plate Tectonics Activity

2. What is Geology Geo- Earth Ology is the study of
This activity will help us study the earth by learning what it is made of and how it can be changed

3. 4 layers of the Earth
Crust
Mantle
Inner core
Outer core

4. Milky Way- cut in half
Chocolate- crust- thinnest layer made of rocks and soil (land we walk on and under the sea)
Caramel- mantle- holt molten rock, what would come out of a volcano
Light brown layer- outer core- liquid iron
Bottom layer of chocolate- inner core, solid iron and is the hottest layer (almost as hot as sun)

5. Plate Tectonics
Plates- large section of the Earth’s crust that slowly move over partially melted rock in the upper mantle
This movement explain how the Earth’s surface has changed over time and we can predict how it will change in the future
 formation, movements, collusions, destruction of Earth’s crust

6. PT- Activity Frosting- mantle Graham cracker- crust
Spread frosting on wax paper
Place 2 graham cracker on frosting – make sure they are touching

7. Divergent Plate Boundary
Move plates apart to expose mantle  spreading zone.
When plates move apart, it creates cracks in the Earth called rift valley
Allows hot, melted rock to come up through the cracks  volcano opening is formed
Sea floor spreading- new sea floor created

9. Convergent Plate Boundary
Push plates back together until the middle forms a ridge
When plates collide they create mountains this is called a collision zone
Appalachian mountains – Africa collided with North America during formation of Pangea
Destroy sea floor- ocean plates more dense than land plates, when they converge ocean plates slide under land plates

10. 3 sub types Ocean to ocean Ocean to continental
Continental to continental

12. Transform Plate boundary
Slide the edges of plates against each other
This horizontal grinding and sliding of the plates causes earthquakes
This is called a shearing fault
A fault is a fracture in the Earth’s crust
New Madrid Fault- runs along the eastern border of Missouri
San Andreas Fault- most studied
