4. Short Answer # 1 LAND USE/URBANIZATION 1. Over the last hundred years the land cover and land use in Audubon, and throughout Southern New Jersey, has greatly changed. A)Explain how land use and land cover have changed in our region over the last century? What impact has that had on the environment in our region? B) Overall, do you think cities have a positive or negative impact on the environment? Support your answer with at least two examples. C) How do you think the negative effects of sprawl could be reduced?

5. Short Answer # 2 WATER RESOURCES 2. Clean, fresh water is becoming more of a scarce resource in parts of the world. It is estimated that more than 1 billion people do not have access to clean, reliable fresh water sources. a) How is that possible when more than 97% of the Earth’s surface is covered by water? b) Using the concept of watersheds, explain how overfertilization on a farm in Minnesota could affect fish in the Gulf of Mexico. c) List several benefits and costs associated with building a dam.

6. Short Answer # 3 ATMOSPHERE 3. Our atmosphere is nothing but a thin layer of gases surrounding our planet. a) Explain using at least 3 examples, how our atmosphere makes life on Earth possible. b) Using at least 2 examples, in detail, explain how humans are altering our atmosphere, impacting life on Earth. c) Explain how the element Carbon is responsible for causing the climate on Earth to change. You must include a diagram/drawing to help explain this answer.

7. Short Answer # 4 • a. Which animals would you expect to have the lowest relative populations in this ecosystem, and why? • b. What does this diagram tell us about the importance of biodiversity in maintaining a functioning ecosystem? • c. In the illustration, what do the arrows represent? (aside from “this species is eaten by that one.”) • d. Identify a producer, a primary consumer, and a secondary consumer from the illustration. • e. If the plants and leaves start with 100 units of energy, how much would the grass shrimp and worms get by eating the leaves?

8. Short Answer 5 • Human population growth has had a dramatic impact on Earth’s environment. As we currently reached 7 billion humans living on Earth, how we deal with population in the future may determine the fate of our species. • a) Describe the significance of the population graph above. How has population growth changed over the last 10,000 years? • b) Describe several reasons why it took until 1880 to reach 1 billion people on Earth. • c) Explain how this chart represents exponential growth and what that means for population growth. Why did the population begin to rise so quickly in the last 200 years? • d) If a population is growing at 5% a year, how long will it take to go from 200 million to 400 million?

9. How To Study/Prepare • Look over and study old tests MC questions • Prepare short answer questions before exam • Make cheat sheet • Must be written on paper supplied • Must be turned in by end of class with name on it 4) Play Review Jeopardy Games
