This week is all about the theories of Continental Drift and Plate Tectonics. We have been doing a number of different activities to help understand the concepts.

EVIDENCE TO SUPPORT CONTINENTAL DRIFT
In the early 1900s, Alfred Wegener, wrote about his hypothesis of continental drift.Continental drift is the hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations.
EVIDENCE IN ROCKS
Same Rock Formations on different continents
Similar Rock Types on different continents
EVIDENCE IN FOSSILS
Glossopteris discovered in S.A, Africa, Australia, Antarctica, & India
(found in swampy environments)
EVIDENCE IN CLIMATE
Sediment deposited by glaciers
