1 KEY WORDS
1.1 Fetch - The distance that the wave has travelled
1.2 Swash - Where the wave comes in
1.3 Backwash - Where the wave goes back out
1.4 Constructive Wave - Gentle waves that create things by depositing material
1.5 Destructive Wave - Where strong waves damage something and causes erosion
2 CONSTRUCTIVE WAVE -->
2.1 1. Low wave height 2. Long wave length 3. Powerful swash-pushes material up the beach 4. Weak backwash
3 DESTRUCTIVE WAVE
3.1 1. High wave height 2. Short wave length 3. Weak swash - pushes material up the beach 4. Powerful backwash
4 EROSION
4.1 Hydraulic Action - Sheer force of the water erodes banks etc.
4.2 Attrition - Rocks and pebbles collide with each other and get smaller
4.3 Corrasion - Material carried by the water erodes the coastline
4.4 Corrosion - Chemicals in the water erode the coastline
5 TRANSPORTATION
5.1 Traction - Big rocks roll along the sea bed
5.2 Saltation - Material bounces along the sea bed
5.3 Suspension - Material floats in the water
5.4 Solution - Material dissolved in the water
6 LONGSHORE DRIFT -->
6.1 The waves come in at an angle, however the backwash is always at a 90º angle due to gravity. Therefore, this process is repeated and material is carried down the beach in the opposite direction of the prevailing winds
