Weathering, erosion, and deposition quiz Grade 6 with answers

📚 Quick Study Guide

• 🌍 Weathering: 🍂 The breakdown of rocks, soils, and minerals through contact with the Earth's atmosphere, water, and biological organisms. Types include:
  • 🌱 *Mechanical Weathering:* Physical breakdown (e.g., freeze-thaw).
  • 🧪 *Chemical Weathering:* Chemical reactions (e.g., acid rain).
• 🌊 Erosion: 🏞️ The process by which weathered material is moved by natural forces, such as wind, water, ice, or gravity. Important agents:
  • 💨 *Wind Erosion:* Common in deserts and dry areas.
  • 💧 *Water Erosion:* Includes rivers, streams, and rain.
  • 🧊 *Glacial Erosion:* Powerful movement by ice.
• ⛰️ Deposition: ⏳ The process by which eroded material is dropped or settled in a new location. Examples:
  • 🏖️ *Sediment deposition:* Formation of deltas, beaches, and riverbanks.
  • 🗻 *Landform creation:* Building up of land over time.
