This document contains detailed notes on Moving Plates from Chapter 7: Plate Tectonics of the A Level Geology course. It includes all the information required to secure a top grade in this part of the course. These notes took me many hours to complete and are how I revised for my exams.
, The Evidence for Continental Drift
• The plate tectonic theory suggests that lithospheric plates have
moved to their present positions over a period of time and are still
moving.
• Wegener proposed that 200 million years ago the supercontinent
known as Pangaea began to split apart.
• Alexander Du Toit proposed that Pangaea first broken up into two
large continental landmasses: Laurasia (northern hemisphere) and
Gondwanaland (southern hemisphere).
• Gondwanaland was believed to be made up of South America, Africa,
Antarctica, India and Australia. As a single continent, it had the same
rocks and fossils and was glaciated at the same time.
• Laurasia and Gondwanaland continued their breakup into the
various smaller continents that exist today.
