Weathering is a natural process in which the rocks alter due to the changes in water, air and other organic materials. This is a process which is there in every rock. There are two kinds of weathering, Mechanical in which the rock breaks down into smaller pieces. The other is chemical weathering which is usually caused by water and climatic conditions and it changes the chemical composition of the rock.

The rocks follow a proper pattern during weathering. First there are igneous rocks which are present. When these rocks undergo weathering, they erode and sediments are formed. These sediments eventually become compact and form sedimentary rocks. These rocks remain buried deep beneath the surface of the earth and the heat and pressure convert them into metamorphic rocks.
