Weathering and Erosion Review Questions Grade 5

📚 Quick Study Guide

• 🌍 Weathering: The breaking down of rocks, soil, and minerals through contact with the Earth's atmosphere, water, and biological organisms.
• 💧 Erosion: The movement of rocks and minerals by agents such as water, ice, wind, and gravity.
• 🧊 Types of Weathering:
  • Physical Weathering: Breaking rocks apart without changing their chemical composition (e.g., freeze-thaw).
  • Chemical Weathering: Changing the chemical composition of rocks (e.g., acid rain dissolving limestone).
• 💨 Agents of Erosion:
  • Water: Rivers, rain, and ocean waves.
  • Wind: Carrying sand and dust.
  • Ice: Glaciers moving rocks and sediment.
  • Gravity: Landslides and rockfalls.
• 🏞️ Examples: The Grand Canyon formed by water erosion, and mountains shaped by glaciers.
