Lesson 2
0 likes251 views
The document discusses plate tectonic theory, including how geologists proposed that Earth's crust is made up of plates that move over time. It introduces Alfred Wegener's theory of continental drift, which proposed that continents move apart, and how fossil evidence later helped support this idea. It also discusses how plate tectonics can explain seafloor spreading through processes like magma formation at mid-ocean ridges. Additionally, it examines how mountain formation can occur through the compression and shearing of tectonic plates.

- 7. What causes the Ocean floor to spread
- 8. What causes the Ocean floor to spread Plate Tectonics explain how forces cause the Ocean Floor to spread
- 9. What causes the Ocean floor to spread Plate Tectonics explain how forces cause the Ocean Floor to spread Magma: is hot melted rock that causes tension or a stretch or push on the plates Cooling magma forms the mid-ocean ridge
- 10. How do Mountains form
- 11. How do Mountains form Compression: Squeezing or pushing together of the crust this produces folded mountains
- 12. How do Mountains form Compression: Squeezing or pushing together of the crust this produces folded mountains Shear: Plates rub past another this produces faults
