Vocabulary
Define: water vapor
Water that has transformed into a gas by heat and evaporation
Define: cirrus
hair-like or wispy clouds
What tool measures temperature?
What type of weather is associated with a low pressure system?
typically associated with cloudy, unsettled weather, including rain, snow, or storms
Anna, Elsa Kristoff and Olaf are all characters in what animated movie?
Frozen
Define: condensation
When water vapor cools and turns back into a liquid.
Define: nimbus
rain clouds
What unit do we use to measure humidity?
Percent %
What type of weather is associated with a high pressure system?
fair weather conditions, including clear skies, light winds, and dry conditions
What is James Bond's code name?
007
Define: evaporation
When water warms up and turns into water vapor.
Define: stratus
layered clouds
What unit do we use to measure air pressure?
Bars/Milibars
How are warm air and cold air different?
Warm air is less dense than cold air because the molecules in warm air move faster and spread further apart, causing it to expand and rise, while cold air is denser due to its molecules being closer together, making it sink.
What U.S. state is home to Acadia National Park?
Maine
Define: humidity
a measure of the amount of water vapor and moisture there is in the air
What 3 things are required to create a cloud?
1. water vapor (moisture)
2. cooling air temperatures (using caused by rising air)
3. condensation nuclei (small dust, ash, or other particles floating in the air)
What tool measures air pressure?
A barometer
What happens when relative humidity reaches 100%?
2. Water condenses into droplets or ice crystals on particles in the air forming clouds.
3. Droplets or ice crystals fall as precipitation when they become too heavy.
On average, which grows faster: Fingernails or toenails?
Fingernails
Define: condensation nuclei
small particles of ash, dust, or pollution in the atmosphere where water vapor can condense.
How does a cloud form? Hint: There are 3 main steps.
1. Warm water evaporates to form water vapor and rises into the atmosphere.
2. As the water vapor rises, the air cools and the vapor condenses back into water.
3. Water needs to condense on a surface, it forms on the particles in the air making a cloud.
What tool measures himidity?
Sling Psychrometer
Which direction does wind always flow?
Wind always flows from an area of high pressure to an area of low pressure. Colder, high pressure air is denser and pushes the warmer less dense away.
How many noses does a slug have?
Four
