004 - River
Geographic Knowledge and Understanding
The formation of typical river landforms, including waterfalls, floodplains, meanders, levees and deltas.
Physical processes of fluvial erosion, transportation and deposition interact to produce different landforms. The relative power of the processes will determine the size of the landform which is created. Global climate change has the power to influence fluvial processes.
- To be have knowledge and understanding of how the river processes of erosion, transportation and deposition interact to produce typical river landforms.
There is no need to define the terms above now as we will doing that throughout the course of the lesson.
Activity One - Watch
The clip that you are going to watch gives you a review of the different processes that help to form landforms and will also give a summary of how a waterfalls, meanders, levees, floodplains and deltas are formed. Watch the clip and make notes on how the five key landforms are created. Do do this we will be using videonot.es.
Activity Two - Draw
Draw the digram above but label it using different colours for the processes (erosion, transportation, deposition), landforms and velocity. You can link this to the Bradshaw Model that we discussed in a previous lesson.
Activity Three - Create
Produce an IB DP Geography level revision sheet for one of the fluvial landforms that is mentioned in the syllabus point. The group will be divided into pairs to look at a different landform per team. Your revision sheet should be no longer than 1 side of A3 and you will be using LucidPress. The finished articles will be shared on the department website - www.nationsinsoc.org
- Waterfall and Gorge
- V-shaped valley and U-shaped valley
- Meander and Ox Bow Lake
- Pools and Riffles
- Flood plain
The revision sheet should include the following:
- An explanation/definition of the landform.
- How the processes of erosion, transportation and deposition have produced the landform.
- Maps/diagrams to show the process of formation.
- Examples of the landform(s) from at least two different countries and at least one image/map of each.
- How the landform can be used by humans.
Exam Style Question
To what extent are floodplain landforms the result of river deposition? [10 marks]
