Name the three major kinds of rocks - Sedimentary- deposition of material at the Earth's surface and within bodies of water Metamorphic- transformation of existing rock through heat or pressure Igneous- cooling and solidification of magma and lava Has the African plate been stationary or mobile and have other plates moved towards or away from it? - Relatively stationary while other plates have moved away from it causing no collisions ad therefore no mountain chains formed. How was the A...
