Alfred Wegener in 1912
First proposed that 200 million years ago the Earth only had one giant continent. First proposed that 200 million years ago the Earth only had one giant continent.
Wegener believed today’s continents broke apart and drifted into their current locations.
Wegener supported his theory in six ways Wegener supported his theory in six ways:
#1. First he used the fit of the continents.
The bulge of Africa fits the shape of the coast of No. America while Brazil fits along the coast of Africa.
#2. The size of the Himalayans indicate a huge collision. Wegener believes this was caused by the collision between India and Asia.
#3. He discovered identical fossil species on several different continents.
He knew that it was physically impossible for most of these organisms to have traveled or have been transported across the vast ocean.
#4. Found broad belts of rocks in Africa and South America that are the same type which is rare.
#5 Also the Mountain Ranges of the Appalachian (No. Amer.) and the Caledonian (Europe) match up.
#6. Marks left by glaciers on rocks in Africa, India, South America and Australia make no sense, unless these continents were joined and arrayed around the South Pole.
Wegener’s Continental Drift theory was not readily accepted by the science community of his day because he could not explain how the continents were moving.

In 1912, Alfred Wegener First proposed that 200 million years ago the Earth only had one giant continent. First proposed that 200 million years ago the.
By Alfred Wegener. scientists have been gathering data in support of the Continental Drift Theory for a very long time In 1912 first proposed… 200 million.
Chapter 14 Plate Tectonics. Lesson 1- The Continental Drift Theory Pangaea- All continents were joined as one Super continent. Continental Drift- Theory.
Continental Drift. The continents are moving At one time all the continents were connected Pangaea.
Jigsaw Puzzle Fit It is likely that the first clue that the continents were once joined together came from the close fit between the west coast of Africa.
Plate Movements The Basics. Continental Drift Theory Alfred Wegener (1910s) stated that some 250m yrs ago a single giant continent called “Pangaea”
I will examine the evidence for the theory of plate tectonics

If you look at a map of the world, you may notice that some of the continents could fit together like pieces of a puzzle…..the shapes of the coastlines.

Restless Continents. Continental Drift Hypothesis proposed by Alfred Wegener in early 1900’s Said that continents had once been part of a single large.
Plate Tectonics Drifting Continents. Pangaea The Earth once had a single landmass that broke up into large pieces, which have since drifted apart. This.
What is it? Continental Drift - Earth’s continents were once joined in a single landmass, and gradually moved, or drifted apart. People thought this for.
