Earth/Environmental Science
Week 12 Homework: Due Friday, 5/1
1. The average surface water temperature off of the coast of Ecuador is 21 degrees Celsius. The average surface water temperature
off of the coast of Brazil at the same latitude is about 27 degrees Celsius. Explain why there is such a difference in water
temperature between these areas at the same latitude.
2. Describe the difference between surface currents and density currents. Include in your answer how each forms, as well as the
“direction” the current travels.
3. Explain why fresh water is considered a limited resource.
4. Describe one way humans can have a negative impact on the recharge zone. How does it happen? What are the effects?
