ENVS 1001 Milestone 1,100% CORRECT

Document Content and Description Below

Which statement about projected human population growth below is incorrect? Innovation and technology have little influence on projected population growth. If population growth dramatically ... slows, the Earth's population will be 7.4 billion by 2050. The population in 2050 will reach 10 billion if growth continues to increase. Continuing to slow the growth at current rates will result in a population of 8.9 billion by mid-century. CONCEPT T he Impact of Population Growth 2 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. provisioning cultural regulating supporting CONCEPT B iodiversity 3 Which of the following is the best example of how the public can apply environmental science? Purchasing only organic vegetables after learning about the damaging effects of pesticides Regulating air and water emissions from a nearby power plant Studying the impact of a proposed natural gas pipeline that crosses a protected environment Administering free vaccinations for children in a developing country CONCEPT A pplying Environmental Science 4 Choose the statement below that is NOT true about early Earth's atmosphere. The ozone layer was quite thick. There was no free oxygen. Conditions were favorable for forming chemical bonds. Both ammonia and methane were present. CONCEPT Earth's Formation 5 Match the graph image with its corresponding type and common use. Bar graph, which is used to show differences in quantifiable characteristics across groups Scatter plot, which is used to show the relationship between two characteristics Map, which is used to show the location of various phenomena Line graph, which is used to show a trend in a characteristic relative to changes CONCEPT G raphic Literacy 6 Choose the best explanation of the distinction between environmental science and environmentalism from the options below. Environmental science is a subjective examination of human interactions with the environment and environmentalism is an objective assessment of how humans relate to the environment. Environmental science is dedicated to protecting the environment while environmentalists concentrate on the legal, political and social ways to do so. Environmental science holds that humans have a responsibility to be aware of their impact on the environment and environmentalism is a social movement that urges action. Environmental science remains objective, while environmentalism is concerned with ethical questions about right and wrong concerning the environment. CONCEPT Environmentalism 7 Melissa believes that all living creatures are similar in their desire to avoid pain. Melissa holds which of the following environmental ethical positions? Biocentric Ecocentric Ethnocentric Anthropocentric CONCEPT E thics and Stewardship 8 Factors that led to population growth during the Industrial Revolution and the Green Revolution include all of the following except . improvements in technology improved methods of transportation more government regulations increased food productivity CONCEPT H uman Arrival and Expansion 9 Most scientists believe the event that led to the extinction of the dinosaurs was caused by a(n) . volcanic eruption massive tidal wave asteroid impact supernova CONCEPT C ontinental Drift and Major Extinctions 10 Select the true statement about continental drift. All of the continents were combined into Pangaea 275 to 225 million years ago. Continental drift decreased biodiversity on Earth. Tectonic plates are unmoving and permanent. Continents are separated because of shifting oceans. CONCEPT C ontinental Drift and Major Extinctions 11 Plant and animal life faced many challenges when moving from water to land. Select the FALSE statement about this transition. Organisms on land could dry out unless they found a water source. Oxygen levels in the atmosphere were not high enough to sustain life on land. Organisms’ movements changed without water for transport. The development of an ozone layer protected organisms from solar radiation. CONCEPT E arly Life 12 Which statement about human population growth is FALSE? The world population doubled between 1959 and 1999. The global population is expected to peak at 7 billion, then begin decreasing. From 1350 AD to the present, the world has experienced continuous population growth. From 200,000 BC through 8,000 BC, the global population was low. CONCEPT H uman Arrival and Expansion 13 Which of the following is a global sustainability issue that was NOT identified by the Brundtland Report in 1987? Food security Pollution Epidemics Overpopulation CONCEPT S ustainability 14 Select the item below that is biotic. Dirt Water Air Bacteria CONCEPT Environmental Science 15 Choose the sentence that describes Thomas Malthus and his contributions to environmental awareness. He was the first chief of the United States Forest System and served from 1905 until 1910. His book Silent Spring, published in 1962, raised public awareness of harmful agricultural practices. He wrote “An Essay on the Principle of Population,” published in 1798, that warned of the dangers of human overpopulation. He wrote the book The Population Bomb, in which he discussed the negative effects of human population growth. CONCEPT Environmentalism 16 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 . reach a conclusion form a hypothesis analyze data conduct an experiment CONCEPT Science & The Scientific Process 17 Which of the following describes an effect of an environmental issue experienced at the local level? Warming temperatures and rising sea levels are affecting many island populations. An entire species of deer has become extinct because of overhunting. Everyone left work for the day after mold was discovered growing on a ceiling tile. Highway noise and pollution have increased dramatically ever since this section of interstate was built. CONCEPT T ime, Scale, and Impact 18 Which of the following correctly defines biodiversity? The preservation of the environment due to ethical beliefs A community of living organisms interacting with their environment Protects the environment in ways that can continue indefinitely The variability of plant and animal life in a given area CONCEPT B iodiversity S ustainability 19 Choose the statement that does NOT accurately describe the environmental impacts of population growth. More food is needed, so humans clear more land for crops, which contributes to deforestation and loss of oxygen production from trees. More energy is needed, which leads to the use of renewable natural resources, which contributes to their depletion. More water is needed, which leads communities to rely too much on freshwater systems, which contributes to an overall decrease of potable water supplies. More energy is needed, which leads to the burning of fossil fuels, which contributes to an increase in CO2 in the atmosphere. CONCEPT T he Impact of Population Growth 20 Select the date and time of human arrival according to the one-year calendar model based on the Big Bang theory. December 1, 12:00 a.m. December 15, 11:55 p.m. December 30, 11:59 p.m. December 31, 11:54 p.m. CONCEPT Earth's Formation 21 Select the misleading graph from those below. CONCEPT G raphs in Environmental Science 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. A scientist, because the language is non-technical so that others will understand A politician, because the statements are general and may be biased A scientific journal, because it has been peer-reviewed and verified The media, because the language is controversial and sensationalistic CONCEPT S cientific Literacy [Show More]
