1. Landscapes Day 2 Agents of Erosion

2.  How does the bedrock beneath a mountain and plateau differ?  To the right, draw the drainage pattern for water going down a mountain  Name the five agents of erosion: Do Now

3. Aim, Learning Target & Agenda  AIM:  What causes the landscape to change over time?  Learning Target:  I can list the agents of erosion and explain how each type changes the landscape.  Agenda:  Do Now  Mini Lesson  Practice Problems

4. Mini Review  What’s makes a region a landscape? What has to be similar?

5. Mini Review  What’s makes a region a landscape? What has to be similar?  shape  climate  The way the underlying rocks are positioned

6. Mini Review  When we talk about shape we’re often talking about ELEVATION  How high something above sea level  What is the name of a landscape that has high elevation and high relief?  MOUNTAINS

7. How are Landscapes Changed?  Many landscapes are changed due to WEATHERING and EROSION  Weathering:  The change in rocks that occurs when they are exposed to conditions at Earth’s surface  Erosion:  Any process that moves sediments

8. Conditions of Weathering (Or Agents of Erosion)  Water (precipitation)  Rain  Snow  Ice freezing  Glaciers  Running water (streams, rivers, etc)  Wind  Ice  Waves

9. The topography of a region depends on...  the balance at any given time between forces that uplift the land and agents of erosion that wear down the land.

10.  Depending on the COMPOSITION of rocks, certain rocks RESIST erosion.

11. Water erodes the mountain V-shaped valley

12. Wind and Waves deposit sand on beach

13. Waves and high/low tide moves sand, etc onto the landmass

14. Water from highland source Rocks erode, water rushes downhill

15. Water erodes the rock starting to create a V – shaped valley
