Load The sediment carried by a river. Meander A sweeping curve or bend in the river’s course. The loop of an old meander that is no longer connected to the river channel by Oxbow lake flowing water. The pool of water found at the base of a waterfall. Plunge pools are erosional Plunge pool features created by abrasion and hydraulic action of the plunging water. A river beach formed of sand and gravel that is deposited on the inside bend Point bar of a meander. The gradual backward movement of a landform due to the process of erosion. Retreat A waterfall retreats towards the source of a river as it is eroded. The gentle slope on a river beach (or point bar) that is formed by deposition Slip-off slope of sediment on the inside bend of a meander. Source The starting point of a river. Transport The movement of material as it is carried by a river through the landscape. Tributary A smaller river which flows into a larger river channel. When the force of water, that is wearing away the landscape, is concentrated Vertical erosion downwards. Coastal process and landform Erosion caused by friction when waves carry sand or pebbles and use them to Abrasion wear away the landscape. Natural arch-shaped features in cliffs on the coastline that are formed by the Arches erosion of a cave in a headland. A type of erosion where rocks smash against each other making them smaller Attrition and more rounded. Backwash The flow of water back into the sea after a wave has broken on a beach. The laying down of material in the landscape. Deposition occurs when the Deposition force that was carrying the sediment is reduced. Faults Major cracks in rocks caused by earth movements The distance over which wind has blown to create waves on the sea. The Fetch greater the fetch, the larger the waves. Hydraulic action Erosion caused when water and air are forced into gaps in rock or soil. The sudden collapse of a hillside under its own weight. Landslides are Landslide sometimes triggered on a cliff by erosion at the foot of the slope. Longshore drift A process by which beach material Is moved along the coast. Offshore bar A feature on the sea bed formed by the deposition of sand. The gradual backward movement of a landform due to the process of erosion. Retreat The coastline retreats due to the erosion of a cliff.
