Glacial erosion quiz with answers for Grade 4 science.

🧊 Quick Study Guide

• ⛰️ Glaciers are huge masses of ice that move slowly over land.
• 💧 As glaciers move, they pick up rocks and sediment, a process called erosion.
• ⛏️ This erosion carves out valleys and shapes the landscape.
• 🏞️ Common landforms created by glacial erosion include U-shaped valleys, cirques, and moraines.
• ⏳ Glacial erosion is a very slow process, taking thousands of years.
