Tectonic Plates - Coggle Diagram

- - - - Lower Portion (Solid)
      - Upper Layer (Asthenosphere)
        
        Crust + Upper Layer = Lithosphere : Tectonic Plates
    - - Oceanic: Younger and Less Dense
      - Continental: Older and Denser
  - - - Slab Pull: As plates are heavy, Gravity acts on them and pulls them apart
        
        Ridge Push: When convection currents coverge and plates move together.
    - - The Earth's core is extremely hot
        
        Heat from the core rises into the Mantle
        
        Convec. Currents in the mantle cause the semi-molten rock to move in a circular motion
        
        Movements in the mantle drag the tectonic plate sideways
