Meanders and Oxbow lakes

• What are meanders in geography?

  Large bends in a river
• In which courses of a river do meanders occur?

  Middle and lower courses
• What are the steps in the formation of meanders?

  1. Current is faster on outer bends.
  2. Erosion occurs, forming river cliffs.
  3. Current is slower on inner bends.
  4. Eroded material is deposited, forming slip-off slopes.
• Why does more erosion take place on the outer bends of a meander?

  Because the river channel is deeper
• What forms on the inside of a bend in a meander?

  Slip-off slopes
• What happens to meanders over time?

  They get larger and larger
• How do oxbow lakes form?

  Erosion causes bends to get closer
• What occurs when the river breaks through the land between bends?

  The river flows along the shortest course
• What happens to the meander after an oxbow lake forms?

  It gets cut off
• What eventually happens to oxbow lakes?

  They dry up back into land
