2. Theory of Continental Drift
All the continents were once joined into a ‘Super Continent’ known as PANGAEA
This continent has since broken up into the 7 continents we know today
Proposed by Alfred Wegener
German scientist – 1912
Not accepted by scientific community until 1930’s

4. Continental Drift Evidence
The Continents of the
Earth seem to fit
together like a
jigsaw puzzle

6. Glacial Striations found on edges of continents…where continents were thought to have been joined together

7. Evidence: Ancient Climates
Geologists had found glacial till of the same age on several continents.

8. Fossil Evidence
Shows that certain species were only found in specific areas…they match up if continents joined
Glossopteris
Mesosaurus

9. match up on different continents. Rock types match.
Mountain Ranges
match up on different continents. Rock types match.

10. What Pangaea might have looked like.

11. Earth’s Tectonic Plates
The Earth’s crust and upper mantle are broken into sections called plates

13. ESRT – Plate Tectonics pg 5

14. How do the Earth’s Plates move?
Convection currents of HOT magma under the Lithosphere push the plates around
The plates ‘ride’ on the magma like rafts
