1. Scientists are currently research new ways to obtain energy from our natural, renewable resources. Which best contrasts the benefits of fossil fuels with the benefits of wave power in the ocean? $
A. Fossil fuels are renewable and inexpensive, while wave energy is nonrenewable and expensive
B. Fossil fuels are nonrenewable and inexpensive while wave energy is renewable and inexpensive.
C. Fossil fuels are versatile and emit little pollution while wave energy is renewable and emits less pollution
D. Fossil fuels are nonrenewable and inexpensive while wave energy is renewable and does not emit greenhouse gases
2. A developer wants to build a new large housing complex on the Cocoa Beach shoreline. Which of the following plans would be least harmful to the environment?
A. filling a wetland area and building the housing complex
B. building the complex at the site of an abandoned condemned hotel
C. building the housing complex in a meadow at the edge of the shoreline
D. clearing a forested area on the shoreline not previously developed to build the housing complex
3. Fossils fuels are an important part of modern society. Which statement best explains how air pollution from fossil fuels affects a marine environment?
A. Air pollution increases oxygen levels in the atmosphere, causing no change in a marine environment
B. Burning fossils fuels accumulates pollutants in the atmosphere, causing smog in a marine environment
C. Air pollution increases oxygen levels in the atmosphere, causing a change in temperature of a marine ecosystem
D. Burning fossil fuels accumulates pollutants in the atmosphere, causing acid rain impacting the pH of a marine ecosystem
4. When new products are produced from recycled materials, less energy is needed to create them. What is another way recycling is beneficial to our environment?
A. it increases pollution in our oceans
B. it increases the amount of municipal solid waste
C. it reduces the amount waste that ends up in landfills
D. it reduces the amount of resources available for human use
5. Corals are marine invertebrates that live in colonies of polyps. They also contain reef builders that secrete calcium carbonate to form a hard skeleton. Over the years, water temperature has increased, causing an increase in microbial activity. This has caused a decrease in coral as a result of bacterial diseases. Which statement best describes a possible effect of the decrease in coral reefs on an ocean ecosystem?
A. stronger ocean currents
B. decreased ocean water salinity
C. removal of sand from the ocean floor
D. loss of habitat for some ocean animals
6. Which of the following examples would not be classified as a human activity that can harm freshwater supplies and come with a high environmental cost?
A. excessive water use
B. removal of vegetation
C. using no-till farming practices (growing crops without disturbing the soil)
D. water pollution
7. Which of the following is an example of non-renewable marine resource?
A. Finfish
B. Shellfish
C. Seaweed
D. Oil
8. A form of water pollution caused by excess nutrients in the environment:
A. Overexploitation
B. Pollution
C. Bioremediation
D. Eutrophication
9. Managing resources appropriately so that we do not run out of damage the environment
A. Biological Magnification
B. Biological Remediation
C. Overexploitation
D. Sustainability
10. Using up environmental species faster than they can reproduce (This is a process)
A. Sustainability
B. Overexploitation
C. Nonrenewable Resource
D. Fossil Fuel
