this concept?

continental drift and the evidence that supports this concept
with 70% accuracy

Continental Drift
Continental Drift: the continents have slowly
move across the Earth’s surface over time
(millions/billions of years). Continental Drift flash

Evidence for Continental Drift: similar endemic
(local) fossils, coral reefs, coal & glacial deposits,
mountain ranges, unique rock types found on
neighboring continents, coastlines match together
like pieces of a jig-saw puzzle
Fossil: trace of an ancient organism that has been
preserved in the rocks.

Pangaea: a supercontinent that formed when
continents drifted together about 300 million years
ago.
How do mountains form?
According to Wegener, mountains occur in narrow
bands along the edges of continents and form
when continents collide and their edges crumple,
fold and fault. VLC Media Player: How Mountains Form Animation
