Do Now 10-26-2018 List the three types of plates and how they move.

Divergent Definition: The boundary between two tectonic plates that are moving away from each other. Features:  rift valley  new lithosphere created; mid-ocean ridge  rift valley  new lithosphere created Example:  East African Rift Mid-Atlantic Ridge List the following on the diagram and color.  Put arrows with the direction Mid-ocean ridge  Rift Oceanic crust Asthenosphere Magma Lithosphere

Convergent Definition: The boundary between tectonic plates that are colliding. Oceanic VS Oceanic Lithosphere Continental VS Continental Lithosphere Denser oceanic lithosphere subducts (sinks) under the other plate. Features:  volcanic island  lithosphere recycled  subduction zones  deep-ocean trenches  Example:  Mariana Islands List the following on the diagram and color.  Put arrows with the direction Trench Volcanic island Oceanic crust Asthenosphere lithosphere Neither plate is dense enough to subduct under the other. Instead colliding edges crumple and thicken, which causes uplift and creates mountain ranges Features:  mountain range Example:  Himalayan Mountains List the following on the diagram and color.  Put arrows with the direction Mountain range              Asthenosphere Continental Crust           

Convergent Definition: The boundary between tectonic plates that are colliding. Oceanic VS Continental Lithosphere Denser oceanic lithosphere subducts (sinks) under the less dense continental lithosphere  Features:  volcanic arc  lithosphere recycled  subduction zones  deep-ocean trenches  Example:  Mout St. Helens List the following on the diagram and color.  Put arrows with the direction Trench                     Asthenosphere Continental Crust      Lithosphere Volcanic island

Tranform Definition: The boundary between tectonic plates that are sliding past each other horizontally. Plate edges do not slide smoothly past each other.  They fracture and scrape against each other and cause earthquakes.  Features: Faults  Earthquakes  Example:  San Andres Faults List the following on the diagram and color.  Put arrows with the direction Crust Lithosphere asthenosphere
