What You'll Learn
Landslides occur when slopes become unstable due to heavy rain, earthquakes, or human activity. Gravity pulls loose rock and soil downhill, sometimes with devastating speed.
Key Words

Materials Needed
- rocks

Safety First
- Wash your hands thoroughly afterwards and keep the material away from your face.
- Mop up spills straight away so nobody slips, and keep liquids away from sockets.
Steps
Look at the vocabulary words and write a definition for each in your own words.
Model erosion: tilt a tray of soil and pour water from a cup at the top. Observe how channels form. Try adding plants or rocks to slow the erosion.
