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