How are plate movements related to the processes ofthe Earth?
Create Flipbook • Hamburger fold • 3 flaps • Convergent Boundary • Divergent Boundary • Transform Boundary
Convergent Plate Boundaries • plates move towards each other • Continent/continent • High mnts form • Continent/ocean • Subduction occurs • Trenches form • Volcanoes form • Strong earthquakes
Divergent Plate Boundary • plates move away from each other • mid-ocean ridges created through a crack in underwater crust • new crust is formed
Transform Plate Boundaries • Crust neither created nor destroyed • Earthquakes created from stress released when the plates slide along each other • Example: • San Andreas fault in California

Tectonic Plates • Earth’s crust is broken into pieces called plates • These plates are part of the lithosphere and move on top of the asthenosphere • Boundaries are drawn by studying earthquakes and volcanic eruptions.
