5. Discuss the following: diagrams would be useful for this part. As well list several examples of each. a. Plate Separations b. Plate Collision c. Shear Boundaries d. Mantle Convection

a. Plate Separations: Diagrams of plate separations can help visualize the process of seafloor spreading and the formation of new oceanic crust. Examples of plate separations include the Mid-Atlantic Ridge, where the North American and Eurasian plates are moving apart, and the East African Rift Valley, where the African plates are also moving apart.<br /><br />b. Plate Collision: Diagrams of plate collisions can help illustrate the formation of mountain ranges and the subduction of one plate beneath another. Examples of plate collisions include the collision of the Indian and Eurasian plates to form the Himalayas, and the collision of the Nazca and South American plates to form the Andes Mountains.<br /><br />c. Shear Boundaries: Diagrams of shear boundaries can help show the movement of plates past each other and the resulting earthquakes. Examples of shear boundaries include the San Andreas Fault in California, where the Pacific and North American plates are sliding past each other, and the Queen Charlotte Fault in Canada, where the Pacific and North American plates are also sliding past each other.<br /><br />d. Mantle Convection: Diagrams of mantle convection can help explain the movement of heat and material within the Earth's mantle and the resulting plate tectonics. Examples of mantle convection include the upwelling of hot material at mid-ocean ridges, where new oceanic crust is formed, and the sinking of cold material at subduction zones, where one plate is pushed beneath another.
