Activity One - Watch

Watch the clip below and just be amazed at how the landscape changes when it is impacted by ice and water.

Activity Two - Describe

Before we even start to look at landforms created in periglacial areas we need to look at what a periglacial area is and what its characteristics are. Answer the following questions using the images above and the useful resources below:

• • 1. What are periglacial areas?

    2. Where can periglacial areas be found?

    3. Describe the climate of periglacial areas.

    4. What is permafrost?

    5. Describe the three different types of permafrost.

       1. • Continuous

          • Discontinuous

          • Sporadic

    6. Why is permafrost found at higher altitude closer to the equator? 

    7. What is talik?

    8. What is the active layer?

    9. Why is the active layer important for landforms created in periglacial areas?

Activity Three - Processes and Movement

There are a number of key processes that occur in periglacial areas and these help to either break up the rock, transport it or deposit the rock.

Process

• • 1. Describe the process of freeze-thaw.

    2. Describe how chemical weathering occurs?

Movement

• • 1. What is gelifluction and how does it occur?

    2. What is frost heave and how does it occur?

    3. What is frost creep and how does it occur?

Activity Four - Periglacial Landforms

Now you know how material is weathered and how it can move we can begin to look at the different landforms found in periglacial areas. As the syllabus point focuses on four so shall we. Copy and complete the table below using the images, the slide share and the suggested text book below.
