1 AIM: What is continental drift and what evidence supports this concept? OBJ: Given notes and activity sheet SWBAT explain continental drift and the evidence that supports this concept with 70% accuracy DN: Watch Continental Drift Simulation; HW check- Convection & the Mantle Activity Sheet ACT: Introduction to Continental Drift, Evidence for CD, CD past, How do mountains form? HW: Text, read p. 18-22; Complete Drifting Continents Activity Sheet; Work on Being A Scientist Packet; Interim, Jan 22.

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

5 Glacial Deposits

6 Coal Deposits

7 Mountain Ranges

8 Rock Types

9 Pangaea: a supercontinent that formed when continents drifted together about 300 million years ago.

11 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.
