Tic-Tac-Tonic

4. When two tectonic plates move towards each other and collide
5. made from Transform boundaries
7. Tectonic plates that are at the bottom of the ocean
9. happens at a convergent boundary and is when a denser plate is pushed down and beneath a less dense plate
11. 1st theory describes the history of Earth’s Surface and said the continents were once connected but have since drifted apart
12. Supercontinent incorporated most all of the landmasses on Earth
15. solid fragments of weathered rock are eroded (moved) and then dropped into a new place
17. made Plate Tectonic Theory
18. When two plates slide past each other and makes Fault lines and usually earthquakes
19. study of shape of Earth’s surface & it’s physical features

1. mechanical or chemical processes that break rocks into smaller pieces
2. Seafloor mountain system formed by divergent Oceanic boundaries
3. difference (subtract) in elevation between two adjacent contour lines of a topo. map
6. thicker line marking every 5th contour line of a map
8. Made Continental Drift Theory
10. line on a map that connects points with the same elevation
12. 2nd theory describes the history of the Earth’s surface and said that the lithosphere is divided into plates that are moving on top of the asthenosphere
13. process by which water, ice, wind, and gravity remove and transport sediments
14. map showing the shape and elevation of the land surface using contour lines
16. When two plates move away from each other; continental and oceanic
