  1. Earth Science Rocks!Warm up October 24 Question: How would this rock change after it has been in a riverbed for a long time?

  2. Tropical storm Sandy 14N, 78 W

  3. Earth Science Rocks! MYP Unit Question: How does land change? Area of Interaction: Environment Learner profile: Caring and Principled.

  4. Earth Science Rocks! • Standard: Investigate the scientific view of how the Earth’s surface is formed. • Essential Question: How does human activity cause erosion?

  5. Activating Strategy NOW Write it on the cover of your Erosion foldable! Erosion Power Teaching

  6. Erosion by Human Activity Human activity causes 10 times more erosion of the continental surface of the Earth than all natural processes combined.

  7. Why does this matter? Earth's surface involves a balanced process, where new soil forms at about the same rate as it erodes. • If humans are stripping soil at that rate, nature won't be able to keep up.

  8. Why is this critical?Two Reasons 1. The Earth's human population is growing rapidly 2. Almost all the land that is capable of producing crops is being used.
