Weathering is the force that breaks down the Earth's crust into smaller pieces.

What is erosion?
Erosion is the picking up and carrying away of the smaller materials or pieces caused by weathering.

Point to deposition on the unlabeled anchor chart.
Teacher will judge.

What was demonstrated by Mrs. Gorring crushing the TUMS? Be specific.
Physical Weathering
200
Which layer of the Earth do plants, animals, and humans live on?
The crust.
200
Give an example of physical weathering.
Answer may vary. Teacher will judge.
200
Name the four types of erosion.
Gravity, Wind, Water, Ice
200
What is deposition?
Weathered and eroded rock are "dropped" in a new location.

What was demonstrated when Mrs. G added vinegar to the TUMS? Be specific.
Chemical Weathering
300
Which layer of the Earth is the hottest?
The core--it is as hot as the sun!
300
Give an example of biological weathering.
Answers may vary. Teacher will judge.
300
What is the MAJOR cause of erosion?
Water Erosion
300
What has to happen before eroded rock can drop?
Motion must stop.
300
What is being demonstrated when the container is tilted?
Erosion
400
Which layer of the Earth slowly moves like putty?
The mantle.
400
Give an example of chemical weathering.
Answers may vary. Teacher will judge.
400
When we did our experiment, what happened to the "land" when we increased the slope? Why?
A greater slope caused more erosion because of gravity.
400
Can deposition cause a change in landforms (i.e. mountains, rivers, hills)? How?
Answers will vary. Teacher will judge.
400
What is being demonstrated when the motion stops?
Deposition
500
Which layer of Earth is the thinnest?
The crust.
500
What is the difference between physical weathering and chemical weathering?
Physical weathering only changes the size of the rock (breaks it apart), while chemical weathering changes it completely--like rust or acid rain.
500
Draw a before and after picture of a mountain that has been sand blasted by wind erosion.
See white board. Teacher will judge.
500
What is the root word in deposition? How does it connect to what we're studying in science?
The root word is deposit. This makes me think of depositing money into a bank or depositing trash into the nearest receptacle or coin deposit machines. They all mean to put something in a new place.

Perform the W.E.D. chant.
"Break, Move, Drop" (x2) "Weathering breaks it, erosion takes it, and when the motion stops, deposition drops" "Break, Move, Drop"
