History of Continental Drift Alfred Wagener, 1910 Theory of Continental Drift

CONTINENTAL DRIFT. The continents are drifting on top of the ocean floors. They once were together in a massive continent called Pangaea.

Proof one Map fit of the continents Proof two Fossils of plants and animals where they can not exist. Exactly same rock on two different continents. Evidence of glaciers in deserts and deserts in Alaska

Against this theory No evidence of scarring of seafloor, no debris Could not explain mechanism of movement.

Harry Hesse

Hess a geologist studied the MAR during WWII looking for submarine. Later he helped prove that the sea floor was spreading in the Atlantic ocean. He was also the first head of NASA.

Harry Hess Plates move on the asthenosphere Asthenosphere is an elastic layer between the hard crust and

the molten mantle. In the Mid Atlantic Ridge (MAR) the earths crust is spreading. DIVERGENT BOUNDARY In the Himalayas and Andes the plates are colliding and

building mountains. CONVERGENT BOUNDARY Where an ocean plate is forced under a Continental plate,

Subduction occurs, causing Volacanoes. Italy and Washington State.
