As a result, the cooling of the lava as the melted magma flows down the mountain is another process that significantly contributes to the development of rock at point R.
R is literally located close to the Earth's surface. We now know that beneath rock melting creates magma. This is the method by which igneous rocks are formed. Therefore, cooling is a further igneous rock formation step that will help in the creation of the rocks at point R.
