Question

state landforms formed by river erosion

Answer 1

Hi friend,


Rivers are constanlty modifying their channel and surrounding landscape. As a result of the potential energy (derived from the gravitional force) as well as its kinetic energy (derived from it movement downslope) the river cuts vertically into channel. This creates initially a deepened channel, as a result of hydraulic action and abrasion; solution may also be present if the river cuts down to the bedrock layer. If this process acted in isolation the channel would take on a very acute, steep v-shape form. However, due to surface run-off, soil creep and other mass movements the valley sides become more gentle. Weathering processes may also aid this breaking down of the valley side. Rivers will always choose to take the most efficient route downslope. If the river flow encounters an obstacle of resistence. e.g. 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. It is normal for a river to make subtle changes in direction repeatedly in its flow downslope; in doing so, interlocking spurs form.
