Sand and Gravel. Sand and gravel deposits found on beaches or in rivers and streams, are mostly quartz (silicon dioxide, SiO 2) grains. Weathering of rocks such as granite forms these quartz grains. In the process of weathering, the softer, weaker minerals in granite (such as feldspar) are weathered away.

If the river flow encounters an obstacle of resistence. some densely rooted soil, it will change direction and flow around that obstacle. In doing so, it preserves energy and takes the most efficient route. These changes in direction are the birth of hillside spurs. As the river cuts deeper, its valley becomes more pronounced and recognisable.
