Environmental Science Final Milestone 1 Moss and lichen begin to grow on land revealed by glacial retreat. Over a period of years, these plants are replaced by shrubs and then by taller shrubs. The ecological process that is occurring is called __________. • ecosystem management • secondary succession • species interaction • primary succession CONCEPT Community Ecology 2 Which of the following is a voluntary environmental risk? • Samantha uncovers a wasp nest while painting the eaves. • Duane moves to a city with heavy amounts of air pollution. • Several people fall ill after eating the spinach salad at a restaurant. • Dwight develops cancer after working in the petrochemical industry. CONCEPT Risk 3 The Industrial Revolution was a factor in a global population explosion because as the population increased, cities and their infrastructures grew. Select one statement that is NOT a result of this change. • New forms of transportation led to new mobility for citizens. • Clean water became less accessible. • Energy was more readily available in cities. • Improved food production fed more people. CONCEPT Human Arrival and Expansion 4 Select the energy source that is non-renewable. • A solar farm produces electricity for 2,000 homes. • A dam converts running water into electricity. • A natural gas stove allows chefs to adjust the flame during cooking. • Algae is made into biodiesel. CONCEPT Energy Renewable Energy Non-Renewable Energy 5 Select the example that describes an environmental cause of famine. • Local farmers lack the technical expertise to develop new cultivation strategies. • A country's population continues to increase but incomes decrease steadily. • An area is flooded after heavy rains and all the crops are lost. • A corrupt government is overthrown and the country descends into violence. CONCEPT World Nutrition 6 Choose the true statement about sources of air pollution in the United States. • Natural sources of air pollution include household products. • Non-point sources of air pollution are easier to monitor and control. • Stationary sources of air pollution are also point sources. • Mobile sources contribute about half of man-made pollution emissions. CONCEPT Air Pollution 7 Choose the statement that is NOT true about water availability on Earth. • Household consumption of freshwater is greater than industrial consumption. • Agriculture uses the majority of available freshwater. • One-fifth of the Earth’s population lives with a scarcity of water. • Water use has been growing at twice the rate of population. CONCEPT Water Availability 8 Choose the statement about the impact of an invasive species that is NOT true. • Native species can be displaced or killed. • The health of an ecosystem often improves. • Invasive species can take over forests or croplands. • Humans can be exposed to unknown pathogens. CONCEPT Native and Non-Native Species 9 Which of the following correctly defines biodiversity? • The variability of plant and animal life in a given area • A community of living organisms interacting with their environment • The preservation of the environment due to ethical beliefs • Protects the environment in ways that can continue indefinitely CONCEPT Biodiversity Sustainability 10 Ecosystems provide many benefits to humans, which are termed "ecosystem services." Visiting the Grand Canyon on a school field trip is an example of a __________ service that ecosystems can provide. • regulating • cultural • provisioning • supporting CONCEPT Biodiversity 11 Most scientists believe the event that led to the extinction of the dinosaurs was caused by a(n) __________. • volcanic eruption • massive tidal wave • supernova • asteroid impact CONCEPT Continental Drift and Major Extinctions 12 Choose the statement that accurately describes oil. • It is a liquid form of hydrocarbons found underground that can be burned for energy. • Mined minerals and the heat of radioactive decay produce electricity. • Can be burned to heat water into steam that drives a generator that produces electricity. • Contains methane and occurs naturally in underground pockets. CONCEPT Non-Renewable Energy 13 Select the way that humans can negatively affect aquifers. • Humans build roads, which prevents rainwater from replenishing aquifers. • Humans prefer to use lake water as a source for drinking water rather than aquifers. • Humans line and seal wells to prevent pollutants from entering an aquifer. • Humans build sea walls, which prevents seawater from entering aquifers. CONCEPT Water Supply 14 Which of the following describes a natural source of air pollution? • A dust storm in 1983 dumped 1,000 pounds of topsoil onto the city of Melbourne, Australia. • Oil refineries on the Gulf Coast release benzene and other volatile organic compounds into the atmosphere. • Diesel exhaust from idling school buses is a concern for some parents. • During their vacation, Jim and his family drove their car through several national parks. CONCEPT Air Pollution 15 It was raining as we began our long hike. We took a trail to the east and left the ocean behind us. Soon we were in a large grove of eucalyptus trees. Coming out of the forest, the trail became rocky and the incline became steep. The rain had stopped, but now I was chilly. “I wish the climate would make up its mind,” I grumbled. My mother, a biologist and nature lover, gently corrected me. “Weather is what’s happening at the moment, dear. Climate is weather a certain area has over years.” Which of the following best describes why the temperature has dropped? • The hikers are climbing to a higher elevation. • Rain along the coastline is following them. • A large lake is nearby. • The hikers are walking into a valley. CONCEPT Earth's Features 16 Toxins from chemicals in plastic are being released into the air, causing pollution. Which type of waste disposal most likely caused this phenomenon? • Composting • Landfills • Ocean dumping • Combustion CONCEPT Solid Waste 17 Choose the true statement about water supply and demand. • One idea to cope with water shortages in developed countries is to make it cheaper. • More than three billion people do not have access to easily obtainable clean water. • Industry uses approximately half of all available fresh water on Earth. • The supply of available clean water is decreasing because glaciers are shrinking. CONCEPT Water Availability 18 Current climate change is occurring because __________. • the amount of energy from the sun varies and the heat from radiation can be trapped • clouds and reflective surfaces on Earth absorb radiation and the atmosphere warms • carbon dioxide and methane emit radiation that cannot return to space • greenhouse gases absorb and redirect radiation back into the atmosphere CONCEPT Climate Change 19 Based on the graph, during which decade did the U.S. population reach carrying capacity? • 1990s • 1980s • 1970s • 1960s CONCEPT Population Ecology 20 Which of the examples below describes an effort to address urban sprawl through urban revitalization? • Grass banks with benches line a river running through a city. • Tons of petroleum-contaminated soil are removed from the site of a former gas station. • A new parking lot is constructed to meet shoppers’ needs. • Community members change an abandoned store into a library. CONCEPT Addressing Urban Sprawl 21 Which statement accurately describes the "savanna" biome? • This biome features forests and grasslands that go dormant during the winter. • This biome features tropical grasslands and is located near the equator. • This biome features high levels of biodiversity and is located near the equator. • This biome features a level of permafrost and a short growing season during the winter. CONCEPT Biomes 22 “Threats of an epidemic haunt citizens as the number of unvaccinated children continue to grow. People are frightened of the implications and angry that a few have placed so many at risk.” Choose the most likely source for this quotation. • The media, because the language is controversial and sensationalistic • A scientific journal, because it has been peer-reviewed and verified • A politician, because the statements are general and may be biased • A scientist, because the language is non-technical so that others will understand CONCEPT Scientific Literacy 23 Choose the statement below that is NOT true about early Earth's atmosphere. • There was no free oxygen. • Both ammonia and methane were present. • Conditions were favorable for forming chemical bonds. • The ozone layer was quite thick. CONCEPT Earth's Formation 24 Select the example that describes a non-native species. • This particular species of orchid has remained within the same environment for hundreds of years. • Domestic livestock multiplied rapidly throughout eastern North America after their introduction by English colonists. • Populations of deer and wolves in Arizona have evolved in relationship with each other. • A species of parrot has evolved to occupy a key niche within the Amazon rainforest ecosystem. CONCEPT Native and Non-Native Species 25 Sherman notices the leaves of one tree in his yard begin to change color much earlier than the surrounding trees. He wonders what causes this. Sherman calls a local nursery to ask some questions. If Sherman follows the steps of the scientific method, his next action would be to __________. • conduct an experiment • form a hypothesis • Analyze data • reach a conclusion CONCEPT Science & The Scientific Process
