WJEC Geography Questions and Answers fully solved 2023 Suspension Material carried along in the rivers channel. Usually fine particles. Traction Heavy material usually big boulders that are rolled along the river bed. Transportation the river moves material as bedload, suspended load or dissolved load (in solution). Bedload can be moved by saltation or traction. Tributary A small river that joins a larger one. Upper course The highest stage of a river near to its source. Characterised by large boulders and turbulent water. V shaped valley is usually found in the upper course of the river where the water has considerable erosive power. Vertical erosion leads to the bed getting deeper. The valley sides become unstable and weakened by weathering and eventually collapse creating this. Waterfalls form where the river meets a band of softer rock after flowing over an area of more resistant material. Waterfalls progressively cut back, leaving a gorge. Watershed The high land marking the boundary between two drainage basins Weathering The breaking down of rock by chemical, biological, freeze thaw or onion skin processes. Hydrological Cycle The movement of water around the water system Evaporation When water is heated by the sun, it turns to vapour (gas) and rises (because it is lighter than the surrounding air as molecules spread out through heating).
