Tectonic plates may move because of convection currents that occur in the mantle. What is convection? The transfer of energy as earthquake waves. The transfer of energy due to the movement of matter. The transfer of energy through materials in direct contact. The process that breaks down rocks. 2. What type of organism eats plants and animals? omnivore herbivore carnivore none of the above 3. Which human activity will most likely have a negative impact on global stability? Increasing world population growth Increasing recycling programs Decreasing habitat destruction Decreasing water pollution levels 4. Which of the following are non-biodegradable materials?I: WoodII: PlasticsIII:Styrofoam boxIV: Prawn shell I, II, III, and IV I and II only II and III only II, III, and IV only 5. Two closely related species of birds live in the same tree. Species A feeds on ants and termites, while Species B feeds on caterpillars. The two species coexist successfully because They use different methods of reproduction They interbreed Each occupies a different niche They live in different habitats 6. Untreated sewage promotes the growth of algae and encourage the growth of marine plants. False True 7. Water pollution can affect the ability of organisms to survive. Which of these statements is true regarding the chemical pollution of water? Chemical pollutants are harmful only if present in very high concentrations. Chemical pollution is not regulated Only a few chemicals dissolve in water. Chemical pollutants can come from both point-sources and nonpoint-sources. 8. Millions of automobiles are on roads around the world every day. The image below shows one effect of car travel. What does the image best illustrate? Global warming Urbanization Acid precipitation Air pollution 9. Which of the following can cause pollution?I: Litter and rubbishII: Harmful chemicalsIII: Human wasteIV: Biodegradable materials I, II, III, and IV III and IV only I, II and III only I, III and IV only 10. Which rocks can be changed into sediments by weathering and erosion? Metamorphic All of these Igneous Sedimentary 11. What may result when the environment becomes unfavourable to the organisms?I: The organisms may die.II: The organisms may adapt.III: The organisms may move to another place. I and II I and III II and III I, II and III 12. One job that many governments have is stewardship of Earth's resources. Stewardship is the careful and responsible management of a resource. Why is stewardship of Earth's resources important? It keeps governments stable. It gives people the opportunity to vote. It ensures that resources will not be polluted or used up too quickly. It prevents people from using resources. 13. What are the three factors a niche includes? Food, competition, energy pyramid Habitat, ecology, food Food, Nonliving conditions, behavior Habitat, food chain, oxygen cycle 14. Scientists use absolute dating to determine The physical appearance of fossils The chemical composition of rocks The approximate date of a rock layer or fossil The numerical age of an object in years 15. What are the three types of symbiotic relationships between organisms? Mutualism, competition, predation Symbiosis, commercialism, paralysis Mutualism, commensalism, parasitism All of the above is true 16. The use of plastic materials adds to the pollution of the environment. Which of the following statements explain it?I: They take a very long time to decompose.II: They are produced from natural resources.III: They are waterproof.IV: They produce harmful gases when burnt. II and III I and IV III and IV I and III 17. The burning of fossil fuels can lead to acid precipitation. What do fossil fuels generate that is needed to form acid precipitation? Energy Gas pollutants Particulate pollutants Water 18. Lynnette is categorizing natural resources. Which of these is a nonrenewable resource she should include on her list? Oil Wind Solar energy Water 19. Which relationship is illustrated by a tapeworm living in the intestine of a human? Mutualisms Parasitism Predator--prey Commensalism 20. Coal is a nonrenewable natural resource. Why is coal considered nonrenewable? Coal will never run out. No new coal is being produced on Earth. Coal is being used faster than it is being produced. Coal is used to produce energy and not materials. 21. Which is an abiotic factor that would affect the ability of a species of tree to survive in a particular habitat? Type and number of herbivores present Availability of minerals in the soil Type and number of tree parasites Climax vegetation of the area 22. The source of energy for almost all life on earth is: Sunlight Fungi Water Animals 23. Which of these terms best describes the role of water in this power system? A material resource An energy resource A created resource A nonrenewable resource 24. Which of these food chains is in the correct order? Caterpillar, water lily, frog, snake Snake, frog, caterpillar, water lily Water lily, caterpillar, frog, snake Water lily, frog, caterpillar, snake 25. Adaptation is one of the parts of natural selection. What is an adaptation? An inherited trait that improves chances of survival and reproduction for a group of individuals in a population A process by which inherited traits in a population change over generations A process by which individuals that are better adapted are more likely to camoflage themselves to their environment A group of organisms that can mate to produce fertile offspring 1 out of 25 Time is Up!
