Glacial Processes and Landforms

Active learning helps students grasp glacial processes because the slow, invisible nature of ice movement and landform creation requires tangible, hands-on experiences. Simulating erosion and deposition lets students see cause and effect directly, while mapping and sorting tasks connect abstract processes to real places they can investigate.

Activity 01

• Gallery Walk
• 45 min · Small Groups

Model Building: Simulating Plucking and Abrasion

Provide groups with ice blocks, clay bedrock, sand for debris, and trays. Students freeze water to clay to demonstrate plucking, then drag ice over sand-covered surfaces for abrasion. They sketch changes and label processes. Discuss results as a class.

Explain the processes of glacial erosion, such as plucking and abrasion.

Facilitation Tip

During Model Building: Simulating Plucking and Abrasion, ensure students use jagged ice cubes or coarse sandpaper to emphasize how debris abrades rock and freezes to pluck fragments.

What to look for

Provide students with images of different glacial landforms (e.g., a U-shaped valley, a corrie, a drumlin). Ask them to label each landform and write one sentence explaining whether it is primarily erosional or depositional and why.

Activity 02

• Gallery Walk
• 30 min · Pairs

Card Sort: Erosional vs Depositional Landforms

Prepare cards with images and descriptions of U-shaped valleys, arêtes, moraines, and drumlins. Pairs sort into erosional or depositional categories, justify choices using process knowledge. Groups share one example with the class.

Analyze how glacial movement shapes distinctive landforms like U-shaped valleys and arêtes.

Facilitation Tip

During Card Sort: Erosional vs Depositional Landforms, provide a small set of mixed images first to prevent guessing, then gradually add more to build complexity.

What to look for

Pose the question: 'If a glacier were to advance and then retreat over the same area twice, how would the resulting landforms differ from an area shaped by a single glacial advance and retreat?' Facilitate a discussion focusing on the superposition of erosional and depositional features.

Activity 03

• Concept Mapping
• 50 min · Small Groups

Concept Mapping: Identifying UK Glacial Features

Distribute OS maps of glaciated UK areas like the Lake District. In small groups, students locate and annotate U-shaped valleys, corries, and moraines. They create a key explaining formation processes and present findings.

Compare the characteristics of erosional and depositional landforms in a glaciated landscape.

Facilitation Tip

During Mapping: Identifying UK Glacial Features, supply a simplified base map with only rivers and contours to avoid overwhelming learners before they plot glacial landforms.

What to look for

On a slip of paper, ask students to define one glacial erosion process (plucking or abrasion) in their own words and name one landform created by glacial deposition.

Activity 04

Jigsaw: Glacial Processes Expert Groups

Assign expert roles for erosion, transportation, or deposition. Experts study their process, then mix to teach mixed groups. Each student notes links to landforms and quizzes peers on key terms.

Explain the processes of glacial erosion, such as plucking and abrasion.

Facilitation Tip

During Jigsaw: Glacial Processes Expert Groups, assign roles clearly and require each group to present one landform type with a real-world example.

What to look for

Provide students with images of different glacial landforms (e.g., a U-shaped valley, a corrie, a drumlin). Ask them to label each landform and write one sentence explaining whether it is primarily erosional or depositional and why.

A few notes on teaching this unit

Start with a brief visual overview of glaciers using short time-lapse videos to establish scale and movement. Avoid long lectures about processes; instead, let students discover relationships through structured tasks. Research shows that combining tactile modeling with collaborative mapping strengthens spatial reasoning and retention of landform-process links.

Students will confidently distinguish between erosion and deposition processes and link them to specific landforms. They should explain how glaciers shape landscapes over time, using appropriate terminology and examples from UK case studies like Snowdonia and the Cairngorms.

Watch Out for These Misconceptions

• During Card Sort: Erosional vs Depositional Landforms, watch for students grouping all landforms as erosional because they associate glaciers only with carving.

  Use the card sort to prompt students to physically separate images and justify placements in pairs, referencing definitions on the board. Circulate and ask, 'What evidence in this image shows deposition rather than erosion?' to redirect thinking.

• During Model Building: Simulating Plucking and Abrasion, watch for students believing glaciers only scrape material away without leaving any behind.

  Have students pause after each simulation to observe both the rock surface changes and the debris pile created. Ask them to note where material is moved versus where it remains, reinforcing that deposition is part of the process.

• During Mapping: Identifying UK Glacial Features, watch for students attributing all valleys to rivers, ignoring glacial widening.

  Before mapping, review side-by-side images of V-shaped river valleys and U-shaped glacial valleys. Then, during mapping, ask students to trace valley walls and label features, prompting them to compare shapes and link to erosion processes.
