1. Chapter 2 – Current Issues in Earth and Environmental Science Why is the Earth in trouble?

6. b. Meteorology – Earth’s atmosphere, weather, and climate

8. c. Oceanography - Earth’s oceans, including physical features, life forms, and natural resources

10. d. Astronomy – the position, composition, size, and other characteristics of the planets, stars, and objects in space

14. 2. An integrated science that includes elements of biology, chemistry, and physics 3. Incorporates the impact of human activities , both planned and unplanned, on the environment

20. b. Cultivated plants and domesticated animals for human use Ex. wheat, rice, cows, horses c. Cleared vast amounts of land and used more non-renewable resources

26. b. Non-renewable resources exist in a fixed quantity and can be exhausted; ex. fossil fuels, metals

28. c. Potentially renewable resources can be replenished, as long as they are not used at a rate higher than the rate of replenishment; ex. trees, fertile soil, fresh water

33. 3. More people = less resources - An increase in the human population leads to the use of more natural resources, however, the quantity of these non-renewable resources is not increasing

37. 4. Results in damage to the Earth from extraction and processing - Natural resources must be obtained by mining the earth or seas , and vast quantities of energy must be used to process these resources and convert them to useful products

52. B. Our goal is to become a “ sustainable society ” – one that manages its economy and population size without exceeding the Earth’s ability to absorb environmental impact, replenish resources, and sustain humans and other forms of life indefinitely

54. C. We can use Earth and Environmental science to learn more about how nature sustains itself and how to mimic these processes in human cultures
