Learning Intention. Understand how coastal processes transform the landscape. Examine the landforms created by these coastal processes. FEED. s for these landforms. F. With over four billion people living in coastal areas and the numbers growing rapidly each year, the need to understand and manage these areas is critical. Coastal areas are one of the most dynamic environments on the earth and area being constantly re-shaped by both natural processes and human development. They have both economic and environmental value – and it is these conflicting demands that bring about the need for long-term, sustainable management strategies.. Headlands and Bays. Cliffs and Wave Cut Platforms. Caves, Arches, Stacks and Stumps. Swanage Bay. Example of headlands and bays on the Dorset coastline.. Headlands and bays. How are cliffs and wave-cut platforms formed?. Science Outreach. Interacting Elements of the Coastal System. Types of Coastlines in NZ. Rocky shorelines. Form on high energy coasts where the ocean meets mountains or sea cliffs. Sandy beaches. Mainland, pocket and barrier beaches. Coasts. Table A: fieldwork methodologies. Fieldwork locality. Use of transects (across a feature). Change over time (comparing primary data with secondary sources). Qualitative surveys (analysing perception). What do these words mean?. The . dominant impression. of a piece of writing is the mood, feeling, atmosphere or quality that is the focus of the text. A strong text allows readers to “feel” the mood of the writer. How does the writer do this? Through language!. Coasts Are Shaped by Marine and Terrestrial Processes. Erosional Processes Dominate Some Coasts. Beaches Dominate Depositional Coasts. Larger-Scale Features Accumulate on Depositional Coasts. Biological Activity Forms and Modifies Coasts. Aim: . To know the outline of this topic and to complete the introduction tasks. Sub topics across this option. Enquiry Q1:Coastal processes. Enquiry Q2:Landforms and landscapes. Enquiry Q3:Coastal risks. What do these words mean?. The . dominant impression. of a piece of writing is the mood, feeling, atmosphere or quality that is the focus of the text. A strong text allows readers to “feel” the mood of the writer. How does the writer do this? Through language!. Aim: We must know and understand the following:. What do they look like? What factors influence their formation?. What is coastal erosion?. Specification content. Starter – . High and low energy coastlines. WHAT IS COASTAL EROSION? Coastal erosion is the endless reshaping of shorelines by waves, currents, tides, storms, ice, rain and groundwater seepage. Human activities, like construction, dredging, CO Interacting Elements of the Coastal System. Types of Coastlines in NZ. Rocky shorelines. Form on high energy coasts where the ocean meets mountains or sea cliffs. Sandy beaches. Mainland, pocket and barrier beaches. Learning objectives. To explain . how beach material is transported along the coastline through the process of . longshore. drift. . . To describe how deposition creates coastal landforms: . beaches.
