Activity Description:
Students will use pictures from magazines to identify types of erosion.
Prior Knowledge Needed:
Students should know that erosion changes the shape of the land in many ways. Water, wind, glaciers, and gravity are the agents of change and they create many scenic landscapes.
Materials:
Pictures of landscapes from magazines such as National Geographic, Arizona Highways, or other nature magazines. You may ask students to bring these in or you might see if you IMC has surplus magazines. Worksheet printed below needs to be run-off.
Time Needed:
If students are finding pictures, 2 one hour periods are needed. If pictures are provided to students, one hour should be enough.
Procedure:
1. If students are finding pictures, hand out magazines and explain that you want them to find pictures of Earth landscapes and cut them out. Have students bring their pictures to you and sort through and pick out the best and most representative of the landscapes you want to focus on.
2. Glue the pictures on heavy paper and with a marker place an asterisk on the area of the picture you wish the students to name. Number and laminate the pictures if you wish. (10-15 are needed, you can save them and use them again!).
3. The next day, hand out the worksheet (printed below) and go over the directions with the students.
4. Write a list of the landscape features names on the board (ex. Arch, canyon, valley, butte).
5. Allow students time to work. They will need to pass the pictures around the room so they can see them all. They should fill in their data as they go.
6. Discuss the studentsÍ identifications before they start questions. Make sure they have correctly identified the pictures.
Scoring Guide:
1. Student works to find pictures (some students will be ñluckierî than
others, depending on the magazine they get). 5 points
2. Student completes data table. 15 points
3. Student correctly answers questions. 5 points
Correct Answers:
1. Probably water erosion.
2. Probably not, wind erosion is not a powerful force, it polishes rock surfaces and blows sand around but doesnÍt carry large loads like water or glaciers.
3. Rapid change would be rock falls, landslides, or floods. Slow changes would be arches, canyons, or buttes.
4. Students may need help figuring out what to look at.
Student Worksheet
Introduction:
In this activity you will name the landscapes pictured in the photographs provided by your teacher. You will decide which force of erosion has shaped the feature.
Directions:
1. Look at your first picture. Notice the number on it and make sure you write in your data in the correct place. If you have #5, start on #5 on the data.
2. Write down the name of the landscape feature. Look on the board for a list to help you. Decide which type of erosion was most responsible for making this feature. Write it down on the data table.
3. Pass the pictures around the room until you have seen them all.

What types of erosion act on a river valley? Tell what each one does.
Correct Answer:
Water erosion: water carries rock out of the valley and digs deeper into the valley floor.
Gravity: pulls rock down from the sides of the valley.
Wind: blows soil into the rivers, rounds and polishes remaining rock.

Describe a rapid change that erosion causes. Describe a slow change that erosion causes.
Correct Answer:
A landslide, rock fall or flood can change EarthÍs surface quickly. Changes that occur slowly are valley, canyon, and arch formation.
