answer choices . relatively warm, humid air. Investigation 7A: PRECIPITATION PATTERNS 1. 100%. The warmer the air the _____ water vapor it can hold. 5. Maritine Polar Cold humid air, originates over a cold marine climate, often in a cloudy cool to cold climate with lots of precipitation. Humid continental climate, major climate type of the Köppen classification that exhibits large seasonal temperature contrasts with hot summers and cold winters. Consequently, warmer (lighter) air is forced to rise above the sloping front overlying 1. Tags: Question 13 . An air mass is not only large (it can be thousands of miles across and thick), it has uniform temperature (hot or cold) and moisture (humid or dry) properties too. Q. Continental tropic. SURVEY . In other words, humid air is going to have less heavy nitrogen and oxygen -- and lighter hydrogen and oxygen -- in its place. Warm saturated air contains _____ water vapor than cold saturated air. denser than not as dense as 2. more. Arctic, forms in an extremely cold area, usually near the poles,a very cold and dry air mass . An mP air mass is _____. As air masses are "pushed" around the globe by wind, they transport their warm, cool, humid, or dry conditions from place to place. 25%. answer choices . a. denser than not as dense as b. Tags: Question 29 . It is found between 30° and 60° N in central and eastern North America and Asia in the major zone of conflict between polar and tropical air masses. Q. Saturated air has a relative humidity of . Q. Tags: Question 20 . ... Q. Maritime polar. 30 seconds . Maritime tropic. Cold, dry air is colder (denser) air. Maritime Tropical : warm humid air mass, forms in a warm marine climate Continental polar. 50%. The warm air tends to rise along a gentle slope above the cold air and form layers of clouds. Consequently, warmer (lighter) air is often forced to rise above the sloping frontal surface overlying colder (denser) air. Q. c. warm and dry d. warm and humid . The air masses that have the greatest influence on weather conditions in the central United States are __. As with oil and water, a distinct boundary forms between the air masses. Consequently, warmer (lighter) air is often forced to rise above the sloping frontal surface overlying colder (denser) air." When air masses with different densities meet, the two masses do not mix. SURVEY . [X ]denser than [ ]not as dense as 2.Ascending unsaturated (clear) air _____, cooling at about 10 Celsius degrees per 1000 meters of ascent (5.5 Fahrenheit degrees per 1000 feet). When warm air moves over cold air, a warm front forms. less. Warm air masses are less dense than cold air masses, and humid air masses are less dense than dry air masses. 2. > The addition of water vapor to air (making the air humid) reduces the density of the air, which may at first appear counter-intuitive. Lab 7A 1.A mass of cold, dry air is _____ a mass of warm, humid air. 30 seconds . Remember that they have the same number of molecules, but the air with water vapor is simply less dense [source: Schrage]. What type of air mass is associated with cold and humid air? SURVEY . "A mass of cold, dry air is _____ a mass of warm, humid air. So there you go. Ascending unsaturated (clear) air cooling at about 10°C per 1000 m of ascent (5.5°F per 1000 ft.). In the experiment, the oil represented a warm air mass and the colored water a cold air mass. Lighter or heavier depends on the density of the volume considered. 0%. Density can make a same volume to be lighter or heavier. To get an easy perception, same volume of cotton and iron bar weighs different due to their densities. b. cold and humid. answer choices . a. cold and dry .
