A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere.
Most earthquakes occur along the edge of the oceanic and continental plates. The earth's crust (the outer layer of the planet) is made up of several pieces, called plates. The plates under the oceans are called oceanic plates and the rest are continental plates.
That answer sounds great! You might also want to add that the cell cycle is thrown out of control by the mutations that occur. Cancer is fundamentally the accumulation of reproduced mutated cells.
