<em>1. An occurrence that is not a characteristic of global warming is;</em>
B. Stabilization in the sea level due to warm weather
<u>A warming climate can cause seawater to expand and ice over land to melt, both of which can cause a rise in sea level.</u>
<em>2.</em> <em>A non-impact of global warming on ecosystem is;</em>
D. Food and supplies increase
<u>Climate change not only affects ecosystems and species directly</u>
<em>3. A factor that contributes to the strength of hurricanes is;</em>
A. Warmer ocean temperatures
<u>Hurricanes start simply with the evaporation of warm seawater, which pumps water into the lower atmosphere. Once hurricanes move over cold water or over land and lose touch with the hot water that powers them, these storms weaken and break apart.</u>
<em>4. A practice that does not protect the environment is;</em>
D. Frequent usage of a SUV
<u>Car pollution is one of the many major causes of global warming. Cars and trucks emit carbon dioxide and other greenhouse gases, which contribute one-fifth of the United States' total global warming pollution.</u>
<em>5. A vehicle that is most likely to be fuel efficient is the;</em>
D. Gas-electric hybrid car
<u>Hybrids are the most gasoline efficient of all cars</u>
<em>6. Scientists predict that global warming will cause Ethiopia to experience;</em>
D. Greater frequency of drought-related conditions
<u>The environment is directly impacted by drought. Drought can affect water sources, land, fish and wildlife and plant communities. A lack of water and reduced ability for soil to support crops can affect fish, animals and plant life.</u>
<em>7. A majority of the greenhouse-gas emissions released into the;</em>
C. Carbon dioxide
<u>Carbon dioxide (CO2) makes up the vast majority of greenhouse gas emissions from the sector.</u>
<em>8. The main human activity that contributes to global warming is;</em>
E. Burning of fossil fuels
<u>The burning of fossil fuels by humans is the largest source of emissions of carbon dioxide, which is one of the greenhouse gases that allows radioactive forcing and contributes to global warming. </u>
<em>9. A statement that is true regarding where pollution is most evident is;</em>
A. Areas with a high population density
<u>As people age, their bodies are less able to compensate for the effects of environmental hazards.</u>
<em>10. A human activity that would best support global efforts to improve the environment and to reduce global warming is;</em>
B. Riding a bicycle to a nearby playground
<u>Riding a bike provides a fairly fast and dependable mode of transportation that just happens to save money, getting fit and helping to reduce global warming.</u>
