Vocabulary
The atmospheric conditions, along with short-term changes, of a certain place at a certain time.
Weather
Liquid precipitation that falls to Earth
Rain
Water vapor enters the atmosphere when water at the ocean's surface is heated....is called:
Evaporation
Measures air temperature on a scale
Thermometer
A person can create a cloud by exhaling from their mouth outside on a cold day. What do we call that type of cloud (near the surface of Earth)?
Fog
Water, in liquid or solid form, that falls from the atmosphere.
Precipitation
Precipitation that reaches Earth's surface as frozen water
Snow
When water vapor cools as it rises into the atmosphere and forms back into a liquid:
Condensation
Measures air pressure on a dial
Barometer
What is the name given to individuals who study weather?
Meteorologists
The force that a column of air applies on the air or surface below.
Air pressure
Solid precipitation that forms in repeated updrafts in a cloud...usually during thunderstorms
Hail
The process by which clouds are able to form...remember, warm meeting cool cause this:
Condensation
Measures wind speed using cups that spin
Anemometer
Which weather variable is not used to forecast weather:
wind speed, wind direction, evaporation, precipitation, air pressure, temperature
evaporation
The amount of water vapor present in the air compared to the maximum amount of water vapor the air could contain at that temperature.
Relative humidity
Precipitation that changes from snow to rain and back to snow
Sleet
Clouds produce this in solid or liquid form once they become too heavy and dew point is reached:
Precipitation
Measures the water vapor content of the air (humidity)
Hygrometer
In terms of air temperature, the average _________________ of molecules is higher in warm air than in cold air.
Kinetic energy
The temperature at which air is saturated and condensation can occur
Dew point
What factor determines the form of precipitation that ultimately falls to Earth's surface?
Air temperature
When snow at the top of a mountain melts, how does it ultimately end up back in oceans?
Surface run-off
Measures Dewpoint
Psychrometer
Why is it hard to breathe on the top of a very tall mountain?
Less air pressure = less oxygen
