| What influences the size and energy of waves ? ♡ | How long the wind has been blowing, the strength of the wind & how far the wind has travelled (the fetch) ♡ |
| What is swash ? ♡ | When a wave breaks and water is washed up on the beach ♡ |
| How are waves created ? ♡ | By wind blowing over the sea, which creates friction - producing a swell in the water, the energy of the wind causes water particles to rotate inside the swell, this moves the wave forwards ♡ |
| What is backwash ? ♡ | Water running down the beach ♡ |
| What are destructive waves ? ♡ | Waves created in storm conditions which wave energy is high and has traveled over a long fetch, they tend to erode the coast ♡ |
| What are constructive waves ? ♡ | Waves created in calm weather, when they break they deposit material which builds up beaches ♡ |
| What is hydraulic action erosion ? ♡ | Trapped air in joints and cracks on a cliff face, when a wave breaks the trapped air is compressed which weakens the cliff and causes erosion ♡ |
| What is abrasion erosion ? ♡ | When rock and sand in waves grind down cliff surfaces like sandpaper ♡ |
| What is attrition erosion ? ♡ | When waves smash rocks and pebbles on the shore into each other, and they break up and get smoother ♡ |
| What is solution erosion ? ♡ | There's acid in sea water which dissolves some rocks such as chalk and limestone ♡ |
| How is material in the sea transported ? ♡ | The material is eroded from cliffs, transported by long-shore drift along the coastline and then brought inland by waves ♡ |
| What is long-shore drift ? ♡ | Continual swash and backwash transports material sideways along the coast. This movement of material is called long-shore drift and occurs in a zigzag ♡ |
| What is saltation ? ♡ | Material which is bounced along the sea bed ♡ |
| What is traction ? ♡ | Pebbles and larger sediment which is rolled along the sea bed ♡ |
| What is deposition ? ♡ | When the sea loses energy, it drops the sand, rock particles and pebbles it's been carrying ♡ |
| What forms of weathering are there ? ♡ | Chemical (rainfall) & biological (animals and roots) ♡ |
