Plate Tectonics

2. Tectonics Scientific theory that explains how major landforms are created as a result of Earth's subterranean movements
5. Boundary Occurs when two tectonic plates move past one another.
8. A sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action.
10. Ancient continental mass in the Northern Hemisphere that included North America, Europe, and Asia (except peninsular India).
11. Boundary Occurs when two tectonic plates move away from each other.

1. Boundary Where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction.
3. Finding identical or similar in areas separated by vast distances were some of the first clues that scientists used to reconstruct past plate movement
4. Du Toit He suggested the two primordial continents
6. Wegener A German meteorologist who proposed that the continent were once one large landmass
7. Plates Plates that are located beneath the ocean.
9. Known as a single supercontinent
