  1. V-Shaped Valleys & Interlocking Spurs

  2. V-Shaped Valleys • Weathering over time weakens the sides of the valley and continued vertical erosion at the base of the valley causing movement of materials down the valley sides. This creates the distinctive V shape. • V-shaped valleys are found in the upper course of the river with fast flowing water. • Erosion is caused by abrasion and hydraulic action in the river channel which makes a steep sided valley. • The material is then transported away by the river when there is enough energy.

  3. Grand Canyon , an example of a V shaped valley

  4. Interlocking spurs • As there is little energy for lateral erosion the river continues to cut down vertically flowing between spurs of higher land. This creating interlocking spurs. • Interlocking spurs occur when the river flows through a V shaped valley and is forced from side to side around more resistant rocks and outcrops these are called spurs.
