Part Three: Weathering and Erosion

Presentation transcript:

Erosion Directions: - Go to where we left off yesterday. - Skip a few lines beneath weathering and title it Erosion.

Erosion Erosion - the removal of ground materials (soil, sand, rocks) by water or wind. Taking rocks, soil, and/or sand from one place… … and depositing them somewhere else. COPY WHAT IS IN THE BOX

Clip Question List the types of erosion. Taking rocks, soil, and/or sand from one place… … and depositing them somewhere else. COPY WHAT IS IN THE BOX

Types of Erosion 1. Glaciers  a large, slowly moving, river of ICE COPY WHAT IS IN THE BOX

Glacier Example: Iceland - Glaciers carve out huge chunks of land forming canyons and valleys thus creating mountains out of flat land. COPY WHAT IS IN THE BOX

Glaciers – how they form 1.Explain how glaciers form. 2.Describe the climate that can support glaciers. READ ONLY Underneath your Glacier notes, sketch a picture of a glacier.

Effects of Glaciers Appalachian Mountains – Old Glacial Effects Alaska – New Glacial Effects READ ONLY

2. Wind Erosion - wind blows sand and small rocks - This exposes the larger rocks below and smoothes them down. COPY WHAT IS IN THE BOX

Wind Erosion Causes dust storms Harms crops -What would be an economic effect of wind erosion? Create a real example to demonstrate your answer. COPY WHAT IS IN THE BOX Underneath your Wind Erosion notes, sketch a picture of wind erosion.

3. Water Erosion (2 types) A. Rivers  rivers cut through rock carving out canyons COPY WHAT IS IN THE BOX Underneath your River Erosion notes, sketch a picture of River Erosion.

3. Water Erosion – 2 types B. Coastal Erosion – occurs when waves carry beach land out to sea COPY WHAT IS IN THE BOX Underneath your Coastal Erosion notes, sketch a picture of a coastal erosion.

On the move… -You just got offered a job making $20 Million a year as a professional video game player, IPOD tester, internet surfer… -However, you are forced to move to one of the three locations marked on the maps on the next slide. -Unfortunately, each town you have to choose from is in a high erosion area.

Task (only complete this once)  1.Which town would you MOST like to live in? 2.Explain why. 3.Which town would you LEAST like to live in? 4.Explain why. Option A – Witchita, Kansas

Task (only complete this once)  1.Which town would you MOST like to live in? 2.Explain why. 3.Which town would you LEAST like to live in? 4.Explain why. Option B – Gulfport, Mississippi Annual Shoreline Change Moderately DamagedSeverely Damaged Relatively Stable

Task (only complete this once)  1.Which town would you MOST like to live in? 2.Explain why. 3.Which town would you LEAST like to live in? 4.Explain why. Option C – Glacier Bay, Alaska

Task (only complete this once)  1.Which town would you MOST like to live in? 2.Explain why. 3.Which town would you LEAST like to live in? 4.Explain why. Option A – Witchita, Kansas (wind erosion) Option B – Gulfport, Mississippi (coastal erosion) Option C – Glacier Bay, Alaska (glacial erosion) #2 and #4 above must include erosion in your reasoning.

Conclusion – Enacting Laws The mayors of Witchita and Gulfport have asked you to help them solve the erosion problems in the towns. Create three steps you would take or laws you would enact to address problems related to erosion in each town.

Conclusion – Enacting Laws The mayors of Witchita and Gulfport have asked you to help them solve the erosion problems in the towns. – Witchita (wind erosion) – Gulfport (coastal erosion) Choose a mayor to help, you only must pick one. Create three steps you would take or laws you would enact to address problems related to erosion in each town.
