Using the three images above and your own knowledge, explain why coastlines around the world are under threat. What is the land use along the coast at x? The size and shape of coarse sediments can be measured on the beach. The process then starts again, with the erosion of the sea making a new wave cut notch. They are attacked by the immense power of the sea and the weather. They are formed when you get alternate layers of hard and soft rock. Overtime the crack may turn into a cave.
Add an arrow to represent fetch too. Rocks been thrown into the cliffs by waves and breaking off bits of the cliff. Over time this erosion creates a wave cut notch basically an eroded hole at the bottom of the cliff. How vulnerable are different places along the coast at x to coastal flooding and rising sea-levels? Anyone fancy trying this out at home in their sandpit?
You can compare a series of groynes along a length of beach.
The distance between the crest and the trough. Beach material is higher on one side of the groyne. This is judged by eye.
Geography Coursework- Coasts
Sometimes the sea may erode through to the top of the headland following a large crack. Beaches receive their material from longshore drift, constructive waves, cliff erosion and river discharge.
Transportation – LSD 3. Bays are usually more sheltered so there is less erosive power, meaning you often find beaches in bays. Are these hard defences sustainable? Please rank the following statements from 1 most important to 6 least important.
Spread the pebbles out in the swash zone, and place a marker further up the beach to show the gegraphy point for the pebbles. It’s not always caught on camera though. Secondary data sources 1. Responses are limited to positions on a scale.
Geography- Whistable Coast Project
You do not have to take corusework sediments from the beach to the lab. Use a tape measure to find the height of beach material on either side of a groyne.
Resilience How resilient is the coast at settlement x to changing weather patterns associated with climate change? Here is an example. What is the impact on the hard defences on longshore drift and the rate of deposition?
Coasts & Management – GEOGRAPHY FOR & BEYOND
Waves refract around headlands so they experience a lot of erosion forming features like arches and stacks see below. Using the three images above and your own knowledge, explain why coastlines around the world are under threat.
To show the spatial change of land use along your stretch of coastline, the buildings can be marked on a map using colours or geograohy for different types of land use.
Watch the really excellent video to the right hand side. What coastal management strategies are used? Physical impact of coastal management 5. To clarify what we learnt last lesson, watch from minutes on the coasts to the right. Bi-polar analysis Construct your own environmental quality assessment.
Coastal Management – FSC Geography Fieldwork
If you star in the photo, you will gain extra credit. All Geography starts with someone going into the field to find out what’s there.
Task 2 – Now watch the first 2. Choose a small number of categories for the types of land use. Make notes under the following headings please: Beach profiles can also be used to calculate cross-sectional area and the amount of beach material present. You can record your thoughts on the worksheet beneath. Use secondary data to find the rock type used and its density. Shoreline management plans are an essential source to find our more about about erosion and other coastal processes in your chosen length of coastline.
Each sample should be placed in a sealed plastic bag and accurately labelled.
