Who is Wegener and why is he important to plate techtonics? |
|
Definition
| Wegener proposed the idea of Pangea. He is important to plate techtonics because his theory showed that the continents may have drifted away from eachother due to the continental plates. |
|

What is the theory of continental drift and give the evidences of this theory? |
|
Definition
| This is a theory that all of the continents are slowly moving away from eachother. The evidences are Pangea and some animal and plant fossils are found on different continents that are separated thousands of miles away through water. |

What are magnetic stripes and how do they change over time? |
|
Definition
| Molten material rises and erupts at the same time older rock on the ocean floor moves outward on both sides of the ridge. As material cools it forms a strip of solid rock in the center of the ridge. As time goes on the new molten rock pushes the old rocks further away from the ridge. |
