Plate Tectonic History
Courtney D. 1/20/15 Sixth Period
1. What evidence did Alfred Wegener use to support his theory of continental drift?
2. Why do you think people didn't believe the continental drift theory when Wegener first explained it?
3. Who were the 2 scientist that brought forth supporting evidence to Wegener's theory and what was their evidence?
Convergent Boundaries are when plates collide together, mountains, earthquakes, volcanoes, and deep trenches are formed at Convergent Boundaries.
Divergent Boundaries are when plates separate from each other, new land is formed, oceanic ridges, volcanoes, and earthquakes are formed at Divergent Boundaries.
Transform Boundaries are when plates slide past each other, earthquakes are formed at Transform Boundaries
5. What types of movement can occur between plates and what features can form from this moment?
6. What do plate tectonics and ocean trenches have in common?
7. How old are the rocks off East Coast of North America in relation to the rocks right along the Mid-Atlantic ridge?
8. What is a convection current and how does it work?
9. What are the 7 major plate boundaries?
10.What are two bad events that can happen as a direct result of plate tectonics?
11. What are three good things that plate tectonics provide for humans?
