CHAPTER 11 - Section 1: Water Resources E.Q. What is the distribution of Earth's water resources and how are they used? SEV4. Students will understand and describe availability, allocation and conservation of energy and other resources. a. Differentiate between renewable and nonrenewable resources including how different resources are produced, rates of use, renewal rates, and limitations of sources. Distinguish between natural and produced resources. b. Describe how technology is increasing the efficiency of utilization and accessibility of resources. c. Describe how energy and other resource utilization impact the environment and recognize that individuals as well as larger entities (businesses, governments, etc.) have impact on energy efficiency. d. Describe the relationship of energy consumption and the living standards of societies. e. Describe the commonly used (e.g. fossil fuels, nuclear fuels, etc.) and some alternative fuels (e.g.wind, solar, ethanol, etc.) including the required technology, availability, pollution problems and implementation problems. Recognize the origin of fossil fuels and the problems associated with our dependence on this energy source. f. Describe the need for informed decision making of resource utilization. (i.e. energy and water usage allocation, conservation, food and land, and long-term depletion) OBJECTIVES Describe the distribution of Earth’s water resources. Explain why fresh water is one of Earth’s limited resources. Describe the distribution of Earth’s surface water. Describe the relationship between groundwater and surface in a watershed. Water Resources Water is essential to life on Earth. Humans can live for more than month without food, but we can live for only a few days without water. Two kinds of water found on Earth: Fresh water, the water that people can drink, contains little salt. Salt water, the water in oceans, contains a higher concentration of dissolved salts. Most human uses for water, such as drinking and agriculture, require fresh water.
