ae.04 Erosional Landforms

Content

• Statement of inquiry
  • Scientific and technical innovators need to understand how power affects the processes that occur within systems.
• Factual questions [Remembering facts and topics]
  • What is rotational slip? | freeze-thaw weathering / frost shattering? | abrasion? | plucking? | nivation?
  • How are Cirque | U Shaped Valley | Hanging Valley | Arête | Pyramidal Peak formed?
• Conceptual questions [Analysing big ideas]
  • Is there such a thing as a 'textbook landform'?
• Aims of this lesson
  • To have knowledge and understanding of the erosional processes involved in the formation of glacial landforms.

Context

Task 1 - Erosional processes

1. Explain each of the following processes (a diagram or series of diagrams may help):
   • rotational slip
   • freeze-thaw weathering / frost shattering
   • abrasion
   • plucking
   • nivation

Note making frame

Task 2 - Landforms created by erosion - What do they look like?

cirque | U shaped valley | hanging valley | arête | pyramidal peak

2. Add to your note making frame a description of each of the landforms.

Task 3 - Landforms created by erosion - What do they look like in Google Earth on web?

3. Explore each of these placemarks in Google Earth for web. These locations should help you add a geographical examples to your note making frame.

Task 4 - Landforms created by erosion - How are they formed?

4. Use these videos (click on the Time for Geography icons) to add notes to the 'Process of formation' column in the note making frame. Try and split the whole process into three steps and have one step of the process on each line.
