9 ) Use models to explain how the flow of Earth's internal energy drives a cycling of matter between Earth's surface and deep interior causing plate movements (e.g., mid-ocean ridges, ocean trenches, volcanoes, earthquakes, mountains, rift valleys, volcanic islands).

[SC2015] ESS (9-12) 7 :

7 ) Analyze and interpret evidence regarding the theory of plate tectonics, including geologic activity along plate boundaries and magnetic patterns in undersea rocks, to explain the ages and movements of continental and oceanic crusts.

This resource shows an example of a convergent boundary plate.  At a convergent plate boundary, lithospheric plates move toward each other. The west margin of the South American continent, where the oceanic Nazca Plate is pushed toward and beneath the continental portion of the South American Plate, is an example of a convergent plate boundary. This resource shows an example of a convergent boundary plate.

This resource shows an example of a divergent boundary plate. At a divergent plate boundary, lithospheric plates move away from each other. As the two sides move away from each other, magma wells up from the Earth's interior. It then solidifies into the rock as it is cooled by the sea, creating a new ocean floor. The mid-Atlantic ridge, a topographically high area near the middle of the Atlantic Ocean, is an example of a divergent plate boundary.
