B) Climate is controlled by solar energy, and weather is controlled by energy from the ground. C) Climate refers only to precipitation and wind, but weather also includes average temperatures. D) Weather refers to the short-term state of the atmosphere, and climate refers to the long-term conditions. 8 A) Cool air sinks, just as cool or more saline water sinks, and warm air, like warm water, rises. B) Both form currents that flow mostly from cool areas to warm areas. C) Cool water evaporates and rises into the atmosphere, just as cool air expands in areas of low pressure. D) Warm water flows more swiftly than cool water, just as warm winds are stronger than cool winds. 9 A) Earth's shape B) Earth's rotation C) Earth's revolution around the Sun D) Earth's energy flows from the equator to the poles 10 A) strong winds that flow from west to east B) large-scale convection patterns in the atmosphere C) small-scale variations in surface temperatures D) large-scale variances between surface and air temperatures 11 A) 1 B) 2 C) 3 D) 4 12 A) Wind flows from east to west in some cells and from west to east in others. B) Wind flows to the east in the northern hemisphere and to the west in the southern hemisphere. C) Air rises at the equator and sinks in the other cells. D) Air rises in two regions and sinks in two others. 13 A) It is cooled again by falling rain. B) The resulting warm, moist air rises and cools. C) It spreads out horizontally near the ground. D) It becomes saturated with water, causing fog. 14 A) The spinning of Earth forces the warm air away from the equator. B) The warm air cools quickly and spreads away from the equator near the surface. C) The warm air cools and loses its moisture as rain, which is pushed away by rising warmer air. D) Cool air sinks, pushing the warm air below to the north and south. 15 A) It evaporates water from the ground, causing a desert to form. B) It causes large windstorms to form. C) It evaporates water from the ground, causing rain forests to form. D) It causes clouds to form, but no rain falls. 16 A) differences in sunlight reaching Earth's surface B) differences in air temperature and thus air pressure C) global warming in some parts of the Earth system, but not all D) the air to reach an average temperature worldwide 17 A) wind B) clouds C) rain D) thunder 18 A) the seasons B) a year C) the Coriolis Effect D) a heat imbalance
