GeographyASAQA Created by: Gabi ChaseCreated on: 07-04-13 17:32 constructive beach? strong swash and weak backwash 1 of 18 destructive beach? strong backwash and weak swash 2 of 18 as waves approach coastline, what are they effected by? frictional drag resulting from contact with the sea bed 3 of 18 what is a sediment cell? length of coastline thats relatively self-contained with regards to sand/shingle 4 of 18 how many sediment cells in britain? 11 5 of 18 how many tides a day? 2 high tides and 2 low tides 6 of 18 high tide/spring tide? when moon between earth and sun and combined g/p causes a bulge 7 of 18 low tide/neap tide? when moon, earth and sun g/p interferes with each other 8 of 18 what is the regular pattern of tides modified by? nature of the ocean bed, proximity of land masses and effect of coriolis force 9 of 18 macrotidal? more than 4m 10 of 18 mesotidal? 2-4m 11 of 18 microtidal? less than 2m 12 of 18 what is the slowest type of mass movement? soil creep 13 of 18 where does solifluction mainly occur? in tundra areas where soils are often frozen and vegetation is sparse 14 of 18 what speed is mudflows and what angle? 5-15km a year and 5-15 degree slopes 15 of 18 mass movement definition? movement of surface material caused by gravity 16 of 18 composition of sandy beach lower gradiant,less infiltration, more sediment carried down the beach 17 of 18 compositon of shingle beach steeper gradiant, higher rate of infiltration, more sediment moved up the beach due to reduced backwash 18 of 18
