Answer Key

#	Answer
1	The short-term state of the atmosphere at a specific time and place, described by variables such as temperature, pressure, humidity, wind, and precipitation.
2	Examples include temperature, atmospheric pressure, and humidity. Wind speed, wind direction, cloud cover, and precipitation are also common.
3	A barometer.
4	A thermometer.
5	A hygrometer.
6	The pascal (Pa).
7	It tells us how much water vapor is in the air compared with the maximum amount the air could hold at that temperature, usually expressed as a percentage.
8	Because higher temperature increases molecular kinetic energy, which raises the saturation vapor pressure and allows more water molecules to remain in the gas phase.
9	Cooling of moist air to its dew point causes water vapor to condense onto tiny particles, forming cloud droplets.
10	The temperature at which air becomes saturated with water vapor and condensation begins.
11	Approximately 100%.
12	Because there is less air above you, so the weight of the overlying air column is smaller.
13	Air moves from higher pressure toward lower pressure, creating wind.
14	Converging surface air and buoyancy associated with warmer, less dense air cause air to rise in a low-pressure system.
15	As air rises it expands and cools, which can bring it to saturation and cause condensation and precipitation.
16	Weather is the short-term atmospheric condition; climate is the long-term statistical average and variability of weather over many years.
17	From the ideal gas law, higher temperature means greater molecular motion, so the same pressure is achieved with fewer molecules per unit volume, making the air less dense.
18	Land heats faster than water, so air over land warms and rises, creating a pressure difference that draws cooler air from the sea toward land.
19	Land cools faster than water, so air over the relatively warmer water rises and cooler air flows from land toward sea.
20	The apparent deflection of moving air due to Earth’s rotation.
21	They spiral inward counterclockwise around the low-pressure center.
22	They spiral outward clockwise around the high-pressure center.
23	Specific heat capacity and temperature; more generally, the internal energy depends on temperature and composition.
24	Because water has a high specific heat capacity, so it warms and cools more slowly than land.
25	The energy required to change liquid water into water vapor without changing temperature.
26	When water vapor condenses, latent heat is released, which can warm rising air and strengthen convection and storm development.
27	A large body of air with relatively uniform temperature and humidity characteristics.
28	A boundary between two air masses with different temperature and/or humidity.
29	Cold, dense air undercuts warm air more sharply, forcing rapid lifting that can create stronger clouds, showers, and wind shifts.
30	The vertical transport of heat and matter by the motion of air, typically involving warm air rising and cool air sinking.
31	If lifted air is warmer than its surroundings, it continues to rise, enhancing convection and storm growth.
32	They provide surfaces for water vapor to condense on, making cloud droplet formation much easier.
33	Because warmer air above cooler air creates stable stratification that resists rising motion.
34	At the same pressure, warmer air has lower density. Water vapor also has a lower molecular mass than dry air, so moist air can be less dense and more buoyant than dry air.
35	The actual vapor pressure is less than the saturation vapor pressure.
36	It increases saturation vapor pressure, meaning air can hold more water vapor before becoming saturated.
37	Its temperature decreases because it does work expanding against the surrounding pressure, leading to adiabatic cooling.
38	Cooling lowers the saturation vapor pressure, so the air can reach saturation and condensation even if the amount of water vapor stays the same.
39	A larger pressure difference over a given distance creates a stronger pressure-gradient force, accelerating air more rapidly.
40	It implies stronger winds, because tightly packed isobars indicate a large pressure gradient, which produces a stronger pressure-gradient force and faster air motion.
