Cut out the pieces of the Earth from yesterday…all trash in the trash cans please..

3. Add red notes to you definitions on page 36

4. Pangaea
Long ago, all the Earth’s continents were just one giant continent
This giant landmass that broke into our present day continents is called PANGAEA
Supercontinent

5. Have You Ever Noticed How Certain Continents Seem to Fit Together?
Look at this picture of the world. Which continents do you think look like they could fit together?

6. Cut out your puzzle pieces from yesterday and try to fit them together in a puzzle. Go to the next slide when finished to see what they should look like.

7. Glue on the back of page 35
Dot Dot not a lot!

8. Tectonic Plates
These plates are formed from the cracking of the lithosphere.

9. Under every continent is a gigantic slate made of rock.
These are called tectonic plates.
As the plates move apart, land masses move as well.

10. Continental Drift
The theory that the continents moved across the Earth’s surface
Theory of Alfred Wegener
Very very very slow
Inches a year
However, this process is VERY slow. Current estimates believe it took over 225 million years to move as far as they have.
Continental drift

11. Theory of plate tectonics
A theory stating that the Earth’s Lithosphere is broken into huge plates that move and change size over time

12. The Earth is constantly changing
Uniformitarianism
A theory stating that processes shaping the Earth today , such as erosion and deposition also shaped Earth in the past and that these processes cause large changes over geologic time.
The Earth is constantly changing

13. Mid Ocean Ridge HUGE underwater mountain range
Found in all of the Earth’s ocean
Helps explain continental drift
