3. Objective and Starter Objective: Today you will learn about erosion.
Starter: What do you know about erosion?
Create a KWL chart
K—What you know
W-Want to Know
L-What you Learned

4. Background Information
What happens when you step on loose rock or dirt?
What natural events can cause sediment to move?

5. Sediment
Material that is moved by erosion.

6. Erosion
The natural process by which natural forces move weathered rock and soil from one place to another.

7. Deposition
The process by which transported materials are left in a new lactation.

8. Gravity
The force that moves rock and other materials downhill.

9. Mass movement
Different types of movement; these include landslides, mudflows, slump, and creep.

10. Water Erosion Chapter 3 section 2
Mr. Ochoa
6th grade teacher

11. Objective and Starter
Objective: Today you will learn about water erosion. Take out your science books
Starter: What happens when erosion occurs?

12. Background Information
Do you know any major rivers or lakes in the area? Where are they located? Where does the water come from?

13. Runoff
Water that moves over Earth’s surface.

14. Rill
Tiny grooves in soil.

15. Gully
A large groove or channel in soil that carries runoff after a rain storm.

16. Stream
A channel along which water is continually flowing down a slope.

17. Energy
The ability to do work or cause change.

18. Flood Plain
The flat wide area along a river.

19. Meander
A loop like bend in a river.

20. Oxbow Lake
A meander that has been cutoff by the river.

21. Alluvial Fan
A wide sloping deposit of sediment formed where a stream leaves a mountain.

22. Delta
A landform built from sediment from a runoff from the ocean or lakes.

23. load
The amount of sediment a river carries.

24. Drifting Continents Chapter 3 Section 3
Mr. Ochoa
6th grade teacher

25. Objective and Starter
Objective: Today you will learn about waves and wind.
Starter: What happens when sediment is carried down the river.

26. Background Information
How can you explain the sand and waves at the beach?
How do waves affect the beach?
How do you think beaches form?

27. Headland
A part of the shore that sticks out into the ocean.

28. beach
An area of wave washed sediment along a coast.

29. Long shore drift
The process whereby beach material is gradually shifted laterally as a result of waves meeting the shore

30. Spit
A beach that projects like a finger into the water.

31. Sand Dune
A deposit of wind-blown sand.

32. deflation
The process by which wind removes surface material.

33. loess
Fine wind deposited sediment.

34. Glaciers Chapter 3 Section 4
Mr. Ochoa
6th grade teacher

35. Objective and Starter Objective: Today you will learn about glaciers.
Starter: What causes a beach to form?

36. Background Information
Is there a difference between snow that has just fallen or snow that has been on the ground for a long time?

37. Glacier
A large mass of ice that moves slowly over land.

38. Continental glacier
A glacier that covers much of a continent.

39. Ice Age
Continental glaciers that have covered large parts of Earth’s surface.

40. Valley glacier
A long narrow glacier that forms when snow and ice build up high in a mountain valley.

41. plucking
Rocks picked up when a glacier moves across the land.

42. Till
A mix of sediments that a glacier deposits directly on the surface.

43. moraine
A ridge that forms when a till deposited at the edges of a glacier.

44. kettle
A small depression that forms when a chunk of ice is left in a glacial till.
