	The River Conwy - erosion and deposition Duration: 02:07 The River Conwy in North Wales flows through Snowdonia. Freeze-thaw weathering creates scree slopes and erosion and deposition transform the landscape.	river, erosion, deposition, Snowdonia, Wales, water, River Conwy, valley, ice, glaciation, freeze-thaw, weathering, scree, energy

	After the Ice Age - Cromer Cliffs Duration: 02:15 The Ice Age affected lowland areas through the deposition of glacial drift. In Cromer, Norfolk, the coastal cliffs are composed entirely of glacial drift.	ice age, glaciers, lowlands, Norfolk, cliffs, glacial drift, glaciation, ice sheets, beach, chalk, sandstone, granite, marble, Norway

	Underground cave scenery Duration: 02:48 The scenery of underground cave systems is developed by the slow deposition of calcite on the ceiling, walls and floor of the caves. Stalactites, stalagmites and pillars are formed.	pervious, stream, caves, potholes, calcium carbonate, stalactites, stalagmites, pillar, flowstone, Yorkshire Dales, limestone, geography

	Coastal landforms - West Wales Duration: 03:57 The coastline of West Wales is under constant attack from the prevailing winds travelling over the Atlantic Ocean.	Irish Sea, Harlech Castle, ships, Pembrokeshire, prevailing wind, waves, cliffs, erosion, headland, faults, hydraulic action, abrasion, chemical erosion, cave, crack

	Old Harry Rocks - coastal processes and landforms Duration: 04:16 The cliffs around Old Harry Rocks in Dorset are made of chalk. Hydraulic action causes caves, arches, stacks and stumps to form within the chalk.	chalk, headland, bay, refraction, waves, Studland, Swanage, deposition, beach, destructive waves, Old Harry Rocks, cliff, undercutting, erosion, stack, arch, cave, crevice, stump, hydraulic action

	Landforms created by longshore drift and coastal deposition Duration: 02:00 Longshore drift and the formation of spits, barrier beaches and tombolos are explained with case studies.	longshore drift, spit, barrier beach, tombolo, Blakeney, Spurn, Holderness, Slapton, Chesil, Portland, waves, sand, shingle, coastline, wind, Lower Ley, lagoon, CoastReversion

	Rivers - meanders Duration: 01:46 An illustrated explanation of rivers - meanders.	meanders, outside bank erosion, river cliff, slip-off slope, inside bank, deposition, helicoidal flow, riffles, river, physical

	Highland landforms – before and after glaciation Duration: 02:03 A highland landscape is described before, during and after glaciation.	gully, valley, glacier, erosion, transportation, deposition, geography, bitesize

	Lochaber – a glaciated valley landscape Duration: 03:30 The key features of a glaciated valley are described using the Lochaber area of Scotland as an example.	u-shaped valley, glacial erosion, glacial deposition, geography, glaciation, valley floor

	River Tay - middle course Duration: 02:20 Describes the characteristics of the middle course of the River Tay, Scotland.	confluence, river bend, meander, spur, sand, gravel, river load, silt, alluvium, floodplain, erosion, deposition, geography

	How do embankments affect floodwater silt deposition? Duration: 01:45 An explanation of how embankments affect the way silt in floodwaters is deposited - a complex process which can change the course of entire rivers.	silt, embankments, floods, erode, charland, fertile, charland dwellers, river, monsoon

	Waterfalls and gorges - erosion and deposition Duration: 05:19 A description of the formation of waterfalls and gorges and other erosional and depositional processes along the River Conwy in Wales.	geologic time, rocks, upper, plunge pool, debris, undercutting, suspension, rapids, point bar, velocity, depth, helicoidal flow
