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