1. Monday, November 23 rd Entry Task Answer the following question using full sentences, IQIA. 1.Why is fertile land often found on flat land around rivers? 2.Why do caverns form in areas with limestone? 3.What do you call curves and bends in a stream channel? Schedule: 5.2 notes Homework: 5.2 Questions Objective: I can identify the different land features made by moving water. Please have on desk: 5.2 RSG

2. Moving Water Shapes Land

3. Streams Shape Earth’s Surface The land is always higher than the water. Water always runs downhill –This shapes the land by erosion and deposition

4. Drainage Basins and Divides Drainage basin- area of land in which water drains into a stream system Divide-ridge from which water drains to one side or the other Drainage basin Divide

5. Streams Stream is any body of water that flows down a slope along a channel. Streams form from melting snow/ice or rainwater fall Streams form

6. Streams

7. Valleys Valleys are formed as streams flow and carry sediment from the surface of the land. This occurs in high areas and create V- shaped, straight, and narrow valleys Valley

8. Valleys

9. Floodplain Area of land on either side of a stream that is underwater when the stream floods. When streams flood a lot of the sediment carried by the stream is deposited in the floodplain. They are very fertile Floodplain

10. Floodplains

11. Stream Channels As land flattens, streams and rivers widen and take curvier paths Meanders-curves and bends that form a twisting, looping pattern in a stream channel –Moving water erodes the outside bank and deposits sediment inside the banks –May shift position over many years Oxbow lakes- may form during floods where the stream may cut a new channel to bypass a meander.

12. Meanders Oxbow lake Stream Channel

13. MeandersOxbow Lakes

14. Delta Area of land formed by the buildup of sediment at the end (mouth) of a river When a river enters an ocean, the water slows down and the river drops much of its sediment This sediment gradually builds up to form a plain (can be fan shaped and extremely large)

15. Delta

16. Deltas

17. Alluvial Fans A fan-shaped deposit of sediment at the base of a mountain Forms when streams leave steep valleys and enter flatter plains Fan is created when a stream slows down at the base and drops some of it’s sediment at the base of the slope

18. Water Moving Underground Water can soak into the ground and become groundwater Beneath the soil space can become completely filled with water. –Top of this area is the water table –Below water table is groundwater Water table is different according to time and location-can change

19. Watertable

20. Caverns Erosion takes place with this moving underground water. Acidic rainwater can dissolve and carry away rocks that contain limestone. Over time, open spaces are produced- CAVES! –Large caves are called caverns Sink holes are formed when the roof of a cave is too thin to support the weight on the surface

21. Caverns and Caves

22. Sinkholes

24. Sinkhole

26. Tuesday, November 24 th Entry Task 1.Draw a map of a river. 2.Label the river with an arrow to show its direction of flow. 3.Add three small streams that join the river. 4.Label each stream with an arrow to show it’s direction of flow. 5.What is the difference between a drainage basin and a divide? 6.How do streams change as they flow from mountains down to plains? Schedule: Creating Stream Features Lab Objective: I can understand the process of erosion and deposition Homework Finish the lab packet- ISN 91 RSG 5.2- ISN 90 Please have on desk: 5.2 Questions

27. 1. Explain 3 ways water shapes land. Weathering: water can break down rocks. Erosion: water can move weathered rocks. Deposition: water can deposit eroded rocks in a new location. 2. True or False? Water shapes land only on Earth’s surface. If false, rewrite a correct statement. False. Water shapes land on Earth’s surface and underground 3. What does slope (how steep) of a hill or mountain have to do with how water shapes it? If it is steeper then the water moves faster creating narrow, straight valleys. If it is more flat the water moves slower creating curvier, wider streams and rivers. 4. Why is fertile land often found on flat land around rivers? Floods deposit a lot of sediment onto the floodplain, which makes that land good for growing crops 5. Why do caverns form in areas with limestone? Limestone is a rock that is dissolved by acid in rainwater. 6. What do you call curves and bends in a stream channel? Meanders

28. Wednesday, November 25 th Entry Task 1.Explain what features formed and what happened to the sediment on your stream table if the water was moving slow during Yesterday’s lab. 2.Explain any additional stream features you created during your lab. 3.How do you know that you observed erosion and deposition during your lab. Thoroughly explain. Schedule: Read/RSG 5.4 Homework Finish 5.4 Reading and RSG (ISN p. 93) Objective: I can understand how glaciers carve and move sediment Please Have on Desk: Lab Packet
