This document provides information about weathering, erosion, and how they create and change landforms. It defines various terms like physical and chemical weathering, erosion, deposition, sediment, deltas, dunes, mass wasting, landslides, and avalanches. The document is a lesson on these topics for 5th grade students, with vocabulary definitions and review questions to help them understand how weathering and erosion slowly change the earth's surface over time by moving land and forming new landforms.

1. Weathering and Erosion Landforms Palmer – 5th Grade

2. Lesson Goal I understand, recognize, and explain how weathering and erosion create and change landforms on earth

3. Review Last lesson, we learned how the earth’s tectonic plates move and create mountains, volcanoes, and earthquakes.

4. Review

5. Introduction In this lesson, we will learn how land changes and moves and learn some new landforms.

6. Introduction

7. Introduction

8. Vocabulary For this lesson, we will need some vocabulary and notes in our notebooks.

9. Physical Weathering The breaking down of land by wind, water, or ice.

10. Weathering

11. Physical Weathering 1. Give an example of physical weathering.

12. Chemical Weathering The breaking down of land by acids and gases

13. Weathering

14. Chemical Weathering 2. Give an example of chemical weathering.

15. Weathering

16. Weathering

17. Weathering 3. Does weathering change the earth’s surface quickly or slowly?

18. Erosion When land is moved from one place to another by wind, water, ice, or gravity

19. Erosion

20. Erosion

21. Erosion 4. What is it called when land is moved to a different place?

22. Sediment Dirt, rocks, and sand that is moved by erosion

23. Deposition When sediment is deposited, or left after being moved by erosion

24. Dune Sediment deposited by wind and piled into hills

25. Delta Sediment deposited at the end of a river or stream

26. Deposition

27. Deposition

28. Deposition 6. Where do we normally find deltas?

29. Deposition 7. Where do we normally find sand dunes?

30. Mass Wasting When a large amount of land moves downhill

31. Landslide When land moves downhill from gravity

32. Avalanche When a landslide is caused by a large amount of snow sliding downhill

33. Mass Wasting

34. Deposition 8. What force mainly causes mass wasting?

35. Human effect The way humans change the land

36. Human Effect

37. Human effect 9. What is a way humans can effect the land?

38. Conclusion

39. Conclusion

40. Human effect 10. Name three ways land can change over time.
