Magma to granite:Magma rises along the crack and cause intrusive volcanism,in which magma intrudes into and is trapped inside the crust, it is cooled down and solidifies slowly to form intrusive igneous rock,and granite is one of them.
Granite into sand:Under denudation such as weathering,mass movement and erosion, the rock is broken down and the loose material is carried away to form sand
Sand to sandstone: the sand is deposite and sedimented,then lithification occurs in which the sediments are compacted and *cemented to form sedimentary rock.
*Cementation:minerals dissolve in water,such as silica or calcite, cement the loose rock together
