Whats the Weather 2?
100
The atmosphere is a. the layer of gases that surround Earth b. the layer that contains the ozone layer c. the layer of water in the oceans d. the layer in which weather occurs
What is a. the layer of gases that surround Earth
100
Properties of airmasses depend on a. surface over which it is formed b. size of the air mass c. rotation of the air mass d. windspeed of the air mass
What is a. surface over which it is formed
100
the boundary between two air masses.
What is a front.
100
in this pressure system, you can expect sunny, cool, windy weather, with air moving in a clockwise direction
What is High Pressure System.
100
On a weather map an air mass that is very warm and dry would be labeled? a. cP b. cT c. mP d. mT
What is b. cT
200
inner, lowest layer of Earth's atmosphere; where weather occurs
What is the troposphere
200
What kind of weather would a continental tropical air mass that formed over northern Mexico bring to the southwestern United States? a. cold and moist b. warm and moist c. hot and dry d. monsoon rain
What is c. hot and dry
200
occurs when a rapidly moving cold air mass runs into a slowly moving warm air mass
What is cold front.
200
in this pressure system, you can expect stormy weather and precipitation, winds blow in a counterclockwise direction
What is a low pressure system
200
instrument used to measure air pressure
What is barometer.
300
The layers of the atmosphere are classified according to changes in a. altitude. b. pressure. c. density. d. temperature
What is d. temperature.
300
An air mass that formed over the North Pacific Ocean
What is maritime polar
300
Slowly moving warm air mass collides with a slowly moving cold air mass.
What is a warm front?
300
What type of weather is associated with a Cumulus cloud?
What is nice, fair weather?
300
What does a line with blue triangles indicate on a weather map? a) Warmer air is moving into the area, bringing light rain. b) Colder air is moving under warmer air, bringing thunderstorms. c) Faster moving cold air is overtaking the warm air and bringing heavy rain. d) Very slow-moving warm air cannot push the existing cold air, resulting in extended periods of rain.
What is b) Colder air is moving under warmer air, bringing thunderstorms.
400
second layer of the atmosphere and contains the ozone layer
What is the stratosphere
400
An air mass that formed over North Central Canada
What is continental polar
400
sometimes cold and warm air masses meet, but neither one has enough force to move the other
What is a stationary front?
400
lines joining places on a map that have the same air pressure.
What is an isobar
400
What does a line with red semi-circles indicate on a weather map? a) Warmer air is moving into the area, bringing light rain. b) Colder air is moving under warmer air, bringing thunderstorms. c) Faster moving cold air is overtaking the warm air and bringing heavy rain. d) Very slow-moving warm air cannot push the existing cold air, resulting in extended periods of rain.
What is a) Warmer air is moving into the area, bringing light rain.
500
List the layers of the atmosphere in order starting from Earth.
What is troposphere, stratosphere, mesophere, thermosphere, exosphere
500
An air mass that is classified as hot and humid.
What is maritime tropical
500
A warm air mass is caught between two cooler air masses.
What is an occluded front
500
lines joining places that have the same temperature.
What is isotherms
500
What does a line with alternating semi-circles and triangles that face in opposite directions indicate on a weather map? a) Warmer air is moving into the area, bringing light rain. b) Colder air is moving under warmer air, bringing thunderstorms. c) Faster moving cold air is overtaking the warm air and bringing heavy rain. d) Very slow-moving warm air cannot push the existing cold air, resulting in extended periods of rain.
What is d) Very slow-moving warm air cannot push the existing cold air, resulting in extended periods of rain.
