Heat energy and new materials are brought to the surface from the interior by the
tectonic cycle.
rock cycle.
hydrologic cycle.
mineral cycle.

The major rocks of Earth's crust are classified into principal types based on
element composition.
mineral composition.
relative and absolute locations.
three specific rock-forming processes; i.e., the manner in which they formed.
Ocean floor subducts under continents because
the ocean floor is made of mafic material and is therefore more dense than continental material.
the ocean floor has a lower density and therefore sinks more easily.
the ocean floor is made of felsic minerals and is heavier than continental material.
the weight of the continents is so great that they push the ocean floor material downward.
