Answer to Question 1
The connection between the rock cycle and plate tectonics is just one of many examples of how Earth's various subsystems and cycles are interrelated. Heating within Earth's interior results in convection cells that power the movement of plates and magma, which forms intrusive and extrusive igneous rocks. Movement along plate boundaries may result in volcanic activity, earthquakes, and, in some cases, mountain building. The interaction among the atmosphere, hydrosphere, and biosphere contributes to the weathering of rocks exposed on Earth's surface. Plates descending into Earth's interior are subjected to increasing heat and pressure, which may lead to metamorphism, as well as the generation of magma and yet another recycling of materials.
Answer to Question 2
False
