Tectonic plates move. They break and spread apart, rub against each other and eventually descend under a lighter plate, to return to the mantle. The tectonic cycle is our understanding of how these plates come to be, how they move and interact, and where they go when no longer expressed at the surface. read more
Rock cycle is a closed system that explains how different types of rocks are formed and what are the proceses that occur in between, (i.e) metamorphic rocks have to totally melt and become magma, such a way an igneous rock can be formed. Plate tectonics is a system too, but it is based on the theory of continental drift, that argues that new rock is coming out from ridges and emerging, the same way that old rock is being buried to become magma at the mantle. read more
Granite igneous rocks are extruded at volcanos caused by hot spots, and convergent plate boundaries like subduction zones. All igneous rocks the basis of the rock cycle are formed by plate tectonics. The igneous rocks are eroded and turned into sedimentary rocks. The sedimentary rocks layers generally tend to be recycled by plate tectonics. read more
The rock cycle is the system of rock create on earth. It is the system were rocks are created or changed into igneous, sedimentary, or metaphoric rocks. A rock is a solid object composed of minerals. read more
