Continental drift is the hypothesis that was proposed by Alfred Wegener in 1915, that the continents as they are today broke off from a single supercontinent, Pangea, over 220 million years ago and slowly drifted to their present positions.
There are several pieces of evidence that support Wegener's theory include:
Continental Shapes
Glacial Deposits
Cross-Continental Geological Formations
Age of Ocean Rocks and Sediments
Palaeoclimates
Direct Measurement and Fossil Distribution
These are the pieces of evidence that I will be exploring through this blog.
This is what scientists have figured out Pangea the supercontinent looked like over 220 million years ago.
Hannah a good introduction and diagram. May want to edit first paragraph. We will also look at other evidence later for drift such as paleomagnetism and polar wandering.
