Coastal Landforms Caused By Depostion 0.0 / 5 ? GeographyCoastal zonesGCSEAQA Created by: nimrahali12Created on: 07-09-16 16:39 Beaches are formed by? Depostion 1 of 22 Beaches are found? On coasts between the high water mark and low water mark 2 of 22 How are they formed? By constructive waves depositing material such as sand and shingle 3 of 22 What is the difference between sand and shingle beaches? characteristics 4 of 22 How do sand beaches look like? flat and wide 5 of 22 Because? sand particles are small and the weak backwash can move them back down the beach creating a long, gentle slope 6 of 22 How do shingle beaches look like? Steep and narrow 7 of 22 Because? Shingle particles are large and the weak backwash can't move them back down the beach. The shingle particles build up and create a steep slope 8 of 22 How are spits and bars formed? by long shore drift 9 of 22 What are spits? Beaches that stick out into the sea , they are joined to the coast at one end 10 of 22 What is a bar? If a spit sticks out so far that it connects with another bit of mainland 11 of 22 Where do spits form at? sharp bends near the coastline ,for example at river mouth 12 of 22 What does the long shore drift do? Long shore drift transports sand and shingle past the bend and deposits in the sea 13 of 22 What curves the end of the spit? Strong winds and wave can curve the end of the spit forming a re curved end 14 of 22 The sheltered area behind the spit is protected by? from the waves 15 of 22 What happens there? lots of material accumulates in the area,which means plants can't grow there 16 of 22 What happens over time? The sheltered area can become a mud plat or salt marsh 17 of 22 Give an example of a spit? Spurn Head in Yorkshire 18 of 22 When is a bar formed? When a spit joins two headlands togtherer 19 of 22 For example? Slapton in Devon 20 of 22 What does the bar cut off? the bay between the headlands from the sea 21 of 22 What does this mean? A lagoon can form from behind the bar 22 of 22
