Tropical storm Sandy14N, 78 WEarth Science Rocks!MYP Unit Question: How does land change?
Area of Interaction: Environment
Learner profile: Caring and Principled.
Earth Science Rocks!Standard: Investigate the scientific view of how the Earths surface is formed.
Essential Question: How does human activity cause erosion?
6Activating StrategyNOW Write it on the cover of your Erosion foldable!Erosion Power Teaching
Human activity causes 10 times more erosion of the continental surface of the Earth than all natural processes combined.
Erosion by Human ActivityWhy 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.
Why is this critical?Two Reasons1. The Earth's human population is growing rapidly
2. Almost all the land that is capable of producing crops is being used.
