  1. Chunky Weathering and Erosion Earth’s surface breaks into chunks and the chunks move.

  2. The breakdown of rocks at or near Earth’s surface is called? weathering

  3. What are the two types of weathering? Physical and chemical

  4. Which type of weathering actually changes a rock’s composition? chemical

  5. What is it called when ice expands in a crack in a rock? Ice wedging or frost action

  6. Abrasion is a form of which type of weathering? physical

  7. When limestone bedrock dissolves due to chemical weathering it can form? Sinkholes or caverns

  8. An example of biological weathering would be . . . • Plant root in rock

  9. The weathering of bedrock ultimately forms this important material. soil

  10. The driving force of most erosion is? gravity

  11. Which of the following are considered mass movement? soil creeplandsliderock fall They’re all mass movement

  12. V-shaped valleys are carved by? Rivers and streams

  13. True or false – rivers produce sharp edged sediments False – they produce rounded sediments

  14. Draw the cross section from x to y

  15. At what letters will erosion take place? B & D

  16. The area of land drained by a stream is called a? watershed

  17. What type of erosion created this formation? wind

  18. Glaciers carve what shape valleys? U

  19. What arrangement of sediments are left by glaciers? Unsorted

  20. What other evidence of glaciation might be found in a U-shaped valley? Striations or erratics

  21. This glacial formation is called a? • drumlin

  22. This long narrow island is formed by? • Longshore current or wave action

  23. Which erosive force formed these lakes? Glaciers

  24. Where on Earth is this process the most dominant type of erosion? Beaches and deserts

  25. Which erosive force moved this boulder to its present location? Glaciers

  26. A decrease in the velocity of a stream will most likely cause an increase in _______________. Deposition

  27. The Mohawk River runs into the Hudson River. Therefore, the Mohawk would be considered part of the Hudson’s ______________. Watershed
