Mass Movement: Landslides and Slumps

Active learning turns abstract concepts like gravity-driven slope failure into tangible experiences. Students see firsthand how soil composition, water content, and slope angle interact to create instability. These hands-on activities build durable understanding by linking textbook processes to real-world evidence students can measure and map themselves.

Activity 01

• Simulation Game
• 45 min · Small Groups

Model Building: Slope Stability Tests

Provide trays with sand, clay, and gravel to build slopes at different angles. Students add water gradually to observe slumps or slides, measure trigger points, and note stabilising effects of adding grass seeds or pegs. Record results in a class data table for comparison.

Explain the conditions that lead to different types of mass movement.

Facilitation Tip

During Model Building, have students mark the failure plane with colored string so they can trace how the slope changes after each variable adjustment.

What to look for

Present students with images of different mass movement events. Ask them to label each image with the correct type of mass movement (landslide, slump, mudslide, rockfall) and write one sentence explaining a key characteristic visible in the image.

Jigsaw: UK Landslide Events

Divide class into expert groups on events like Holbeck Hall or Boscastle flood-induced slide. Each group researches causes, impacts, and responses using provided sources, then jigsaw teaches others. Conclude with whole-class risk mapping.

Analyze the human and environmental factors that increase the risk of landslides.

Facilitation Tip

In the Case Study Jigsaw, assign each group a different UK event and require them to present both the physical triggers and human consequences before comparing findings.

What to look for

Pose the question: 'If you were advising a community built on a steep, clay-rich hillside, what are the top three factors you would warn them about that could increase the risk of a slump?' Facilitate a class discussion where students share their reasoning.

Design Challenge: Mitigation Blueprints

In pairs, students sketch and justify hazard reduction plans for a hypothetical slope village, incorporating terraces, drainage, or vegetation. Present to class for peer feedback and vote on most feasible.

Design mitigation strategies to reduce the impact of mass movement hazards.

Facilitation Tip

For the Design Challenge, provide a 10 cm by 15 cm baseboard and limit materials to 15 craft sticks, 20 g of clay, and 100 ml of water to force creative solutions within constraints.

What to look for

On an exit ticket, ask students to identify one human activity that can destabilize a slope and one natural factor that can trigger a mass movement. They should also suggest one simple method to reduce the risk of a landslide.

Mapping Walk: Local Risk Assessment

On a school site walk or using maps, students identify slopes, note vegetation cover, and rainfall history to classify mass movement risks. Back in class, plot findings on a shared map and discuss prevention.

Explain the conditions that lead to different types of mass movement.

Facilitation Tip

On the Mapping Walk, give each student a clipboard with a pre-printed grid so they can accurately mark slope angles, drainage patterns, and signs of instability they observe.

What to look for

Present students with images of different mass movement events. Ask them to label each image with the correct type of mass movement (landslide, slump, mudslide, rockfall) and write one sentence explaining a key characteristic visible in the image.

A few notes on teaching this unit

Start with a brief field sketch of a local slope to anchor abstract terms in visible features. Avoid over-reliance on diagrams that show idealized mountains, as UK examples often involve gentle coastal cliffs or railway cuttings. Research shows students grasp rotational slumps better when they manipulate layered materials than when they only view cross-sections. Balance modeling with real-world mapping to build both conceptual and contextual knowledge.

By the end of the sequence, students should confidently classify mass movements, explain multiple triggers, and design simple mitigation strategies. They will use local examples to connect global processes to personal geography, demonstrating both scientific knowledge and applied problem-solving skills.

Watch Out for These Misconceptions

• During Model Building: Slope Stability Tests, watch for students assuming all slopes fail the same way regardless of material.

  Prompt students to test a dry sand slope first, then add water to show how cohesion changes. Ask them to record the angle at which each material fails to build a simple classification system.

• During Case Study Jigsaw: UK Landslide Events, watch for students attributing every event solely to heavy rain.

  Require each group to present both a natural trigger and a human activity from their case study. Use the jigsaw’s final comparison to highlight the variety of causes.

• During Design Challenge: Mitigation Blueprints, watch for students overlooking gravity’s constant pull as a factor.

  Ask teams to calculate the total mass of their slope model before and after adding vegetation or drainage pipes. Have them explain how mass reduction or water removal counteracts gravity’s effect.
