πŸ“š Quick Study Guide

  • 🌍 Weathering: πŸ‚ 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).
    • πŸ§ͺ *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:
    • πŸ’¨ *Wind Erosion:* Common in deserts and dry areas.
    • πŸ’§ *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:
    • πŸ–οΈ *Sediment deposition:* Formation of deltas, beaches, and riverbanks.
    • πŸ—» *Landform creation:* Building up of land over time.
