Geology Flashcards
What is an instrument used to observe air pressure?
Barometer
What is the measure of the amount of energy in air molecules?
Temperature
What are the scales used to measure temperature
Celsius, Fahrenheit, Kelvin, and Degree
What are lines drawn on a map that show areas of the same temperature?
Isotherms
What is it when something changes from a liquid to a gas?
Evaporation
What is it when something changes from a gas to a solid on a cooler surface?
Condensation
What is the amount of water vapor present in the air?
Specific Humidity
What is it when the specific humidity equals the air capacity for holding water vapor?
Capacity
What are instruments for measuring relative humidity?
Hydrometers
What is high fog, mist, or haze?
Dew
What type of clouds are thin feathery or tufted, above 7000 meters, and always made of ice crystals
Cirrus clouds
What type of clouds are low sheets or cloud layers found at different altitudes?
Stratus clouds
What type of clouds are piled in thick fluffy masses that are formed by vertical rising air currents?
Cumulus clouds
What type of clouds are high clouds?
Alto clouds
What type of clouds are rain clouds?
Nimbus clouds
What type of clouds are thunderclouds?
Cumulonimbus clouds
How do raindrops form?
- Water-cloud process
2. Ice process
List the forms of precipitation
Sleet, hail, and snow
What are raindrops that fall through freezing rain that are always small pellets of ice?
Sleet
What is formed in thunderstorms where they begin as frozen raindrops. The updraft pushes ice back into the clouds and another layer of ice is added until it is heavy and it falls
Hail
What is it when water freezes and forms crystals then falls
Snow
