WEATHERING Question: What is weathering and how does it affect the Earth’s surface?

What has happened to this rock formation? It has been weathered.

OBJECTIVE Through an experiment, we will compare the effects of weathering on different sized materials.

Weather What is weathering? Weathering is the wearing away of material. What is weathering? Weathering is the wearing away of material. What is erosion? Erosion is the removal of that material by either wind or water.

EXPERIMENT  Check that your group has all materials.  Follow the instructions on the handout.  Be sure to write down your data in the record sheet.record sheet  Check that your group has all materials.  Follow the instructions on the handout.  Be sure to write down your data in the record sheet.record sheet

CONCLUSIONS  Discuss your findings with your group.  Report to the class.  Class conclusions: Smaller pieces dissolved more than the larger pieces.  Discuss your findings with your group.  Report to the class.  Class conclusions: Smaller pieces dissolved more than the larger pieces.

DISCUSSION What did the shaking of the container represent? Weathering What did the pouring out of the water represent? Erosion

DIFFERENCES What is the difference between weathering and erosion?
