This slide was made for class presentation. It is just a basic. Don't expect much.

1. CONTINENTAL DRIFT THEORY

2. OBSERVING THE MAP
• Abraham Ortelius
• Alexander von Hamboldt
• They had noted earlier that the shapes of continents on opposite
sides of the Atlantic Ocean (most notably, Africa and South America)
seem to fit together.

3. • He was a German astronomer, geophysicist, meteorologists
• Supporting evidence of the Continental Drift Theory
• The father of continental drift
ALFRED WEGENER

4. • All the continents were once connected
• Pangaea – Entire earth
• Continental drift
• The continents had been pulled apart by
the centrifugal force (Polflucht) of the
Earth's rotation or by a small component
of astronomical precession
CONTINENTAL DRIFT

5. CONTINENTAL DRIFT THEORY

6. EVIDENCES

7. THE APPARENT FIT OF CONTINENT
• The coastline of the continents seems to fit together like the pieces
of puzzle

8. FOSSIL CORRELATION
• Cynognathus, Lystrosaurus,
Mesosaurus, Glossopteris’s fossil
found around the continent
• These fossils have been found
either side of the ocean.

9. ROCK AND MOUNTAIN CORRELATION
• Mountain with same structure and rock type found both side of the
ocean

10. • Glacier evidence have been
found in warm areas
• Coal have been found in cold
area
PALEOCLIMATE DATA

11. • All the continents were once
connected in supercontinent
• That’s name was Pangaea
• It existed 250 MYA
THE ORIGIN OF CONTINENTS AND
OCEANS
