DRIFTING CONTINENTS

• 1. Theory of Continental Drift Alfred Wegeners
  theory that all continents were once one landmass
  called Pangea (theory proposed in 1910)

• 2. 200-300 million years before present Pangea
  existed, and later, over tens of millions of
  years, Pangea breaks up to form present landmasses

• 1. Evidence from Landforms Mountain belts that
  match up in South Africa, Argentina, and South
  America Coalfields in North America and Europe
  match up

• 2. Evidence from Fossils Glossopteris plant
  fossils found in Africa, South America,
  Australia, India, Antarctica these seeds are
  not designed to travel a great distance or
  survive ocean travel

DRIFTING CONTINENTS
Glacial striations on rocks show that glaciers
moved from Africa toward the Atlantic Ocean and
from the Atlantic Ocean onto South America. Such
glaciation is most likely if the Atlantic Ocean
were missing and the continents joined.

• 6. Rejection of Wegeners Theory Wegeners
  theory was rejected by most scientists because he
  could not identify the mechanism for how
  continents drift
