Lithospheric Plates

What is a geothermal gradient?

Two Types of Crust http://geology.com/nsta/crust.gif More dense Less dense http://geology.com/nsta/crust.gif

Types of Crust

Lithospheric plates Both types of crust can exist on one plate or on separate plates. (As you can see on the map to the right, the type of crust(s) varies on the different plates.)

Passive vs Active Continental Margins Continental and oceanic crusts do NOT meet on a plate boundary Active Continental and oceanic crusts DO meet on a plate boundary

Start a POM Chart Here Phenomenon Objects Motion/Model (What I observed in the animation including drawn example) (Diagram how the plates were moving in relationship to one another) (Where on Earth this action can be found and examples of land features that can be created?) Objects (Which objects were interacting together?) (oceanic plate/ continental plate) Motion/Model (What actions/ explanations can describe the movements I saw?) *Make sure a majority of your page is open for the Phenomenon column as this will take up the most space. *As we continue in our notes you will be able to add more examples and supplementary information so be sure to leave some space. For this reason do a new page for each new boundary. *You do not need to fill in the Motion/Model column yet.
