Weather Test Review

Which best describes why winds at the beach change direction between day and night?

• because the temperatures over land and over water change

• because warm air over land sinks and stays in place over land

• because cool air rises and is replaced by warm air from the ocean

• because cool air sinks and stays in place over land

Which best describes the type of weather associated with low air pressure?

• clear and dry

• sunny and cold

• sunny with high winds

• cloudy with precipitation

Which has the greatest effect on wind speed?

• precipitation

• cloud cover

• wind direction

• air pressure

Which best explains why a nearby body of water tends to make local temperatures milder?

• Water constantly releases heat into the air.

• Water gains and loses heat more slowly than land.

• Some water stays liquid when everything else is frozen.

• When water is frozen it protects the nearby area from wind.

Which most likely produces clear, cool weather?

• zero air pressure

• stable air pressure

• a low pressure system

• a high pressure system

What is the primary cause of wind?

• the uneven heating of Earth

• precipitation falling to Earth

• many gases released into the air

• water constantly evaporating into theatmosphere

Kaeric looks at the barometer and notices it’s dropping. What kind of weather should he expect?

• cool and clear

• rainy and stormy

• foggy and cold

• sunny and mild

We know that low-pressure systems bring rising air with storms and nasty weather.  What effect does a high-pressure system have on the weather?

• cloud formation and thunderstorms
• calm weather as air sinks
• lots of tornadoes
• the creation of snowstorms

Which of the below statements is true?

• High air pressure means a greater chance of rain
• Low air pressure means a greater chance of rain
• There is no connection between air pressure and weather
• Thunderstorms are the reason that air pressure drops

What instrument measures air pressure?

• barometer
• hydrometer 
• rain gauge
• anemometer
