7th Grade Science Earth/Space
Weathering, Erosion, Deposition
1. Students identify and describe the processes of weathering, erosion, and deposition.
2. Students describe how weathering, erosion, and deposition act together in a cycle that wears down
and builds up Earth’s surface.
Materials: 8.5” x 11” white paper (two pieces per student)
1. Use the Dinah Zykes book for directions on how to make a “pyramid” foldable.
2. Each student should make one foldable.
3. Have students:
Draw and color one example of each of the following: weathering, erosion, deposition. Use
the second sheet of white paper. Drawings should be small enough to fit on one side of the
Cut out the drawings and glue one to each side of the pyramid.
Label each diagram as either weathering, erosion, or deposition.
On the underside of the pyramid, write a definition of that process.
4. Discuss with the students why the pyramid shape represents the “cycle” in nature that continually
wears down and builds up Earth’s surface. Alternatively, students could write a short paragraph
describing this cycle.
