SCHEME OF WORK SECONDARY 3 – 2013 Time No of Periods T1W2 – 3 Learning Outcomes Explain the dynamic nature of coastal environments. Knowledge / Skills Definition of coast – the area where the land meets the sea. Coastal environments are dynamic and changing due to waves, currents, tides and sea level changes, geology, human activities and ecosystem type (mangrove and coral) Explain how waves are generated and the factors influencing them. Explain how wave refraction and the processes which occur when waves break. Distinguish between the different types of waves and their associated coastal environments. Explain the different coastal processes. Describe and explain the formation of cliffs, headlands, caves, arches, stacks and shore platforms. Describe and explain the formation of bays, beaches, spits and tombolos. Generation of sea waves: fetch, wind strength and duration. Wave refraction and processes of wave break: swash, backwash Types of waves and wave environments: constructive/ spilling/swell – low gradient, low energy environment destructive/surging/plunging – steep gradient, high energy environment Coastal processes erosion by waves (abrasion, hydraulic action, attrition and solution) and currents transportation (sediment movement and longshore drift) deposition Formation of coastal landforms erosional landforms (cliffs, headlands, caves, arches, stacks, shore platforms, bays) depositional landforms (beaches, spits, tombolos) Topographic Map Reading Skills Read grid reference, Read direction Interpret scale and symbols Calculate distance Identify physical features associated with coastlines (e.g. headland, cliff, shore platform, tombolo, spit, bay, beach, corals) Describe relief using contour intervals Describe nature of relief using geographical terms Describe cross-sections (including annotation) for interpretations Geographical data and techniques Interpret sketch maps and Topographic maps Interpret aerial photographs; landscape photographs, 1 Activities Resources MOE Initiatives Skills Identify coastal landforms and features shown in topographical maps, photographs and sketches.
