Plate Tectonics (Continental Drift (Evidence (Fossils match (Fossils of…

- - - - Fossils of the same species of animals and plants can be found across the ocean from each other.
      - There is no way the animals could have crossed the Ocean, so the continents must have been connected once.
    - - We can find coal in Antarctica, but coal is organic and only found in tropical places.
      - Antarctica used to be closer to the Equator and formed coal, but moved.
    - - The Earth has changed over time, so it has different layers. Layers from across the ocean match up.
      - If the layers match, the continents must have formed as one giant continent.
    - - When looking at a map, the continents seem to fit together.
      - They used to be connected, but split off from each other.
- - - - This creates a line of volcanoes
- - - - The plates move away from each other
      - This is the only way new crust forms
    - - The plates move towards each other
      - There are two types of crust
        
        Continental
        
        made of silica
        
        Oceanic
        
        Made of metals
      - Three types
        
        Oceanic-Oceanic
        
        Oceanic-Continental
        
        Continental-Continental
    - - Two plates slide past each other
      - Creates earthquakes
      - creates Tsunami
      - Creates volcanos
- - - - The crust is split into tectonic plates which ride the mantle
