Distribution
and plate
boundaries
- The earths crust is broken up into plates
- Moved by convection currents
- Where the convection currents
diverge near the earths crust the
plates move apart
- Where convection currents
converge, plates move toward
each other
- Heat rising and falling inside the mantle create convection currents
- These are generated by radioactive decay in the core
- Plate tectonics
- The movement of the plates in the earth
- Cause earthquakes and volcanoes
- wher two plates meet is called a plate boundary
- This is where earthquakes and volcanoes are most likely to occur
- Plates move apart
- Tensional
- Constructive
- divergent
- Plates move together
- compressional
- destructive
- Convergant
- Plates slide past eachother
- Conservative
- Transform
