Goal: Become experts in the relationship of one sphere to an Earth event (deforestation, volcanic eruption, ice shelf disintegration, hurricane).

Refer to the Week 3: An Example of an ESS Analysis reading if you would like to review E S and S E interactions.

Rubric
Your Sphere Group analysis needs to include:

List the effects of the Event on the Sphere (E > S) with reasoning and support.
List of the effects of the Sphere on the Event (S > E) with reasoning and support.

You should write as many interactions as you can that include accuracy, depth of reasoning, and quality of support. Use the rubric below to evaluate and improve your analysis as your work will be graded based on the rubric being applied to each E > S and S > E interaction you list. Each interaction that earns a 3 or 4 rating will be worth one point toward the maximum four points you can earn for this assignment.
