What is this? Can you guess how it has been formed?

Transportation and deposition L/O: Describe and explain the process of longshore drift Outcome All – list and describe deposition features Most – Explain longshore drift Some – Apply yhis knowledge to a real landscape Starter - look at this map Why do the headlands stick out but the bay does not?

Where has my beach ball gone? Coastal Mystery Where has my beach ball gone? Last year I had a lovely trip to the seaside. I didn’t go to Swanage Bay but instead went to the more natural surroundings of Studland Bay I put down my bucket, spade and beach ball, laid out my towel and fell asleep in the nice hot sun. When I woke up my beach ball had disappeared? Please help me find my beach ball?

How is sediment transported along the coast?

Longshore drift Direction of movement Backwash is always at right angles to the beach swash Backwash This movement of sediment along the coastline is called longshore drift.

Study the photograph of Swanage Beach. Level 4 I say what longshore drift is Level 5 I explain how long shore drift works. Level 6 I explain in detail how longshore drift works. Level 7 I use examples from the Dorset coast to explain how longshore drift works How is this beach different to Studland bay? What is the purpose of the wooden groynes? Add an arrow to the photo to show which direction longshore drift is operating in. Draw your own diagram to explain how longshore drift operates.

What landforms are created by deposition? Learning objectives

Landforms of coastal deposition Beaches Spits Tombolos and Bars

How are beaches formed? Beaches form in sheltered environments, such as bays. When the swash is stronger than the backwash, deposition occurs. Sometimes sand from offshore bars can be blown onto the shore by strong winds. In such cases dunes may form – such as at Studland on the Dorset Coast.

How are spits formed?

Erosion or deposition?

Key Ideas Waves are the result of the wind blowing over the sea. They break as they approach land. Swash and backwash describe the movement of a wave on the beach. Fetch is the distance that the wind has travelled. Sub-aerial processes such as weathering and mass movement occur on the cliff face. Coastal processes of erosion include hydraulic action, attrition, corrosion and solution. Landforms created by erosion include headlands and bays, caves, arches, stacks and stumps. Longshore drift is a method of coastal transport. Landforms created by deposition include beaches, spits, tombolos and bars.
