Suggested learning objective: To be able to describe the distribution of permafrost and periglacial areas across the world and explain the permafrost active layer. Skills objective Interpretation of GIS 2A.3a. Distribution of past and present periglacial landscapes which are underlain by continuous, discontinuous areas and sporadic permafrost with a seasonally active layer. 2A.3b. Periglacial processes include nivation, frost heave, freeze-thaw weathering and solifluction as well as high winds and meltwater erosion. Key terms: Permafrost Nivation Frost heave Active layer Solifluction National / Starter Definitions of key terms. Either linking key terms to definitions or cart sort activity. Main map – students to mark on locations of past and present periglacial areas using information provided. Use geological maps, climate maps, or information: or for diagrams or pictures: Can also use: Closer look at permafrost – encourage students to draw and label a diagram of permafrost showing active layer. Investigate areas of continuous and discontinuous permafrost. Provide students with information on the periglacial processes mentioned in the key terms (nivation / frost heave, etc.) and ask them to compile a table. Depth of information given can vary – for example give process info, but also diagram without labels – ask students to make their own diagram and label it. Plenary
