🔍 Key Concepts

• How current flows in a river bend and where it erodes the bottom most strongly • Difference between the outside and inside of a bend (cut bank vs. point bar) • How sediment is deposited in slower-moving vs. faster-moving water

💭 Think About

• Think about where the current runs fastest when a river curves—does it hug the outside of the bend or the inside? • Where would faster water be more likely to scour (dig out) the bottom and create deeper water? • Where would slower water be more likely to drop mud and sand, making it shallower?

✅ Before You Answer

• Visualize a river bend and identify the fastest current line (thalweg) • Decide which side of the bend is more likely to have erosion versus sediment build‑up • Match that side (erosion/deeper water) with the answer choice description of river location
