WHAT EVIDENCE WAS USED

EARLY TO SUPPORT THE

CONCEPT OF PLATE TECTONICS?

slide3

ALFRED LOTHAR WEGENER, 1880-1930

  • Jig-saw puzzle fit of the continents
slide4

ALFRED LOTHAR WEGENER, 1880-1930

  • Jig-saw puzzle fit of the continents
  • Fit of geologic materials between continents.
slide5

ALFRED LOTHAR WEGENER, 1880-1930

  • Jig-saw puzzle fit of the continents
  • Fit of geologic materials between continents.
  • Global Distribution of plants and animals

2. GEOLOGIC SIMILARITIES

BETWEEN CONTINENTS.

Geologic features formed before the Atlantic Ocean (200 mya) should now be separated by thousands of miles of ocean.

2. GEOLOGIC SIMILARITIES

BETWEEN CONTINENTS.

Geologic features formed before the Atlantic Ocean (200 mya) should now be separated by thousands of miles of ocean.

Rocks of the Appalachian Mountains “end” in Newfoundland, but appear to continue on through the British Isles and Scandinavia.

2. GEOLOGIC SIMILARITIES

BETWEEN CONTINENTS.

Geologic features formed before the Atlantic Ocean (200 mya) should now be separated by thousands of miles of ocean.

Rocks of the Appalachian Mountains “end” in Newfoundland, but appear to continue on through the British Isles and Scandinavia.

400 my old rocks (brown) in South America and Africa fit together like the pattern on jig-saw puzzle pieces.

Evidence of glaciation (typical patterns or erosion and deposition).

Glaciers on land, not sea

Flow patterns match up when reconstructed

250 million years ago

Permian -Triassic
