Read each question carefully and choose the best answer.

This activity contains 34 questions.

	Air pressure is force exerted against a surface by the continuous collision of air molecules.    True  False

	An aneroid barometer works on the basis of measuring the change in ________ of a partially evacuated chamber.   height color shape temperature none of the above

	A meteorologist records standard sea-level pressure as 1013.2 millibars.    True  False

	Galileo invented the mercurial barometer.    True  False

	The atmosphere is confined by   Earth's surface Earth's gravity wind patterns a and b all of the above

	Friction is the ultimate energy source for most wind.    True  False

	Upper air flow is often nearly parallel to the isobars.    True  False

	Which of the following factors are responsible for producing wind?   solar radiation Coriolis effect pressure gradient a and b all of the above

	Variations in air pressure from place to place are the principal cause of   hail snow wind clouds rain

	Which of the following statements is not true about the Coriolis force and the apparent deflection of wind?   the deflection is strongest at the poles the deflection is the result of Earth's rotation the deflection is always directed at right angles to the direction of air flow the deflection affects only the wind speed the deflection is greater for stronger wind

	Air is subsiding in the center of a   surface convergence area chinook jet stream low pressure system high pressure system

	Centers of low pressure are called   cyclones jet streams air masses domes anticyclones

	Fair weather can usually be expected with the approach of a/an   cyclone anticyclone

	In both hemispheres, an anticyclone is associated with divergence of the air aloft.    True  False

	Pressure decreases from the outer isobars towards the center of a cyclone.    True  False

	The general movement of low pressure centers across the United States is from   east to west northeast to southwest north to south west to east south to north

	As wind moves from the subtropical high towards the equator, it is deflected by the Coriolis effect.    True  False

	The polar front is directly related to rising air at the poles.    True  False

	The general position of the jet stream over North America during the hot summer months is closest to   Canada Kansas the Intertropical Convergence Zone (ITCZ) the equator Florida

	Near the equator, rising air is associated with a pressure zone known as the   tropical low equatorial high tropical high equatorial low subtropical low

	The largest influences on atmospheric global circulation are Earth's rotation and   wind energy air pollution ocean currents unequal heating of Earth's surface none of the above

	The only truly continuous pressure belt on Earth is the westerly jet stream.    True  False

	The pressure zone of subsiding, dry air which encircles the globe near 30 degrees latitude, north and south, is the mid-latitude high.    True  False

	The surface winds between the subtropical high and equatorial low pressure zones are the   westerlies monsoon winds sea breezes polar easterlies trade winds

	A mountain breeze is most likely to occur at night.    True  False

	A southeast wind is blowing from the northwest to the southeast.    True  False

	Most local winds are produced as a result of   topographic effects the Coriolis force unequal heating of land and water a and c all of the above

	Wind speed is best measured by a/an   thermometer wind vane cup anemometer aneroid barometer none of the above

	In coastal areas as land is heated to higher temperatures, __________ develops.   an area of lower pressure a breeze an area of higher pressure a land breeze Westerlies

	El Niño is considered   related to the Southern oscillation pressure changes a global weather phenomenon a warm countercurrent of ocean water a warming of the eastern tropical Pacific all of the above

	Global distribution of precipitation is closely related to   the distribution of land and water the latitude global patterns of air pressure and wind patterns the topography all of the above

	In general, the low latitudes receive more rainfall than the high latitudes.    True  False

	The pattern of high and low pressure variations in the eastern and western Pacific is called the   westerlies Peruvian current trade winds Southern Oscillation none of the above

	Which of the following is not a likely possible condition during an El Niño event?   drought in Australia warmer temperatures west of the Rockies trade winds weaken more hurricane damage from the Atlantic warmer ocean water near the Galapagos Islands
