1 Plate tectonics 6.E 2.2 Kim Lachler 2011

2 Plate tectonics theory The Earth's crust is made up of plates. These plates have moved throughout Earth's history. – Used to explain the formation of Mountains Volcanoes Earthquakes Oceans basins

3 Pangaea Was when all the continents where together 2000 years ago. Different theories exist as to why they spread.

4 Types of Boundary Movements 1) Divergent - moves apart - when theyhappen in the ocean –ocean basins are formed.

5 Types of Boundary Movements 2) Convergent - moves together Where ocean meets land – can form volcanoes Where land meets land – can form mountains

6 Types of Boundary Movements 3) Transform - slide past - most (but not all) are in ocean basins

7 Movement Each plate moves as an individual unit – Cities located on the same plate stay the same distance apart. – Cities located on different plates distances change.
