Review Questions are examples of the questions that may appear on quizzes and tests. 1) Nearly all of Earth's surface water is contained in: a) The oceans b) Rivers, glaciers and ice caps c) Holding tanks at the Pepsi Bottling Company in Marion, Illinois 2. The oceans represent far less water than the water (H2O) that is bound to minerals in Earth's interior: a) True b) False 3) Water on Earth (and hence ocean water) most likely formed: a) During the first 0.5 x 10^9 (half billion) years of Earth's history b) From emission (degassing) of volatiles from Earth's interior c) From melting of glaciers and polar ice caps d) (a) and (c) e) (a) and (b) 4) The Scientific method: a) is a belief based approach b) is an empirical approach based on observations and facts c) leads to Laws and Theories that do not change d) can only be used by licensed scientists e) none of the above 5) It is easier to prove a theory or hypothesis than it is to disprove a theory or hypothesis. a) T or b) F 6) The "Goldilocks Principle," in part, suggests that Earth has just the right position in the solar system to allow retention of liquid water and habitability for life. a) T or b) F 7) The course web site has an article about a violent storm in 1992 that tossed 20 containers of rubber duckies overboard. T/F 8) Extreme variation in the ocean's temperature is prevented by water's a) density. b) transparency. c) viscosity. d) heat capacity. e) compressibility. 9) Key physical properties of water include: a) viscosity, which is a measure of the mass per unit volume of water. b) surface tension, which is the property that makes water form into droplets when it’s raining. c) heat capacity, which is a measure of the heat required to change the temperature of water. d) none of the above e) b & c. 10) Latent heat is the a) energy required to change ice to liquid water b) energy required to raise the temperature of 1 kg of water by 1 degree Celcius c) important in energy transfer from the ocean to atmosphere d) energy required to heat liquid water from 10 to 100 degrees e) (a) and (c) 11) Heat capacity is a measure of the temperature of water T/F 12) Land heats and cools more rapidly than bodies of water. T/F Water has a high heat capacity so it warms and cools slower than land: T/F 13) Latent heat is a) the energy need to change the phase of a substance (i.e. ice to liquid water) b) the
