1. Inside Earth 1.2 & 1.5

2. Remember convection currents?

3. Heat from Earth’s core and mantle cause convection currents in the asthenosphere

4. Heat from Earth’s core and mantle cause convection currents in the asthenosphere
REMEMBER – Convection Currents are caused by differences in DENSITY

5. The Earth is broken into separate sections called plates

6. **The Theory of Plate Tectonics states that convection currents in the asthenosphere make the lithospheric plates move.
** = Not in notes packet – Have to add it in.

7. The plates have plate boundaries

8. 3 types of plate boundaries

9. Transform boundaries Place where 2 plates slip past each other
Crust is neither created nor destroyed
Earthquakes occur here
San Andreas fault in California
