TEKS & Objectives
8.9.C. interpret topographic maps and satellite views to identify land and erosional features and predict how these features may be reshaped by weathering.
We will examine how natural processes determine the shape of land.
I will create models to represent the natural world.
1. Watch video.
GG Weathering & Erosion 3-5
2. Review vocabulary and complete quiz.
Erosion Pieces of the Earth’s surface moving from one place to another, usually caused by water or wind
Weathering The process by which earth’s surface is broken down into smaller pieces
Deposition After pieces of the Earth are carried by erosion they are deposited somewhere else. Deposition means to deposit things somewhere else
Mudslides A large amount of mud and water that slides down a mountain due to gravity, usually causing damage and destruction
3. Model weathering with candy.
- Fill two mason jars about halfway with water.
- Place a few pieces of candy in each jar. Chunks of candy cane are perfect!
- One jar is your control. Once it’s got candy and water, leave it alone.
- The other jar is your experimental jar. Shake this jar for a couple of minutes. Pick one of the music videos below to time your shaking.
- Compare the results.
- Does moving water cause the candy to weather more than the still water? Why or why not?
“Shake it Off”
“Jump in the Line”
4. See the destructive power of mudslides.
5. Check out this model of a mudslide.
Speaking of mudslides…
I saw a pretty bad one beginning…
It went downhill from there.
6. “Genius Challenge – Weathering and Erosion”
