Measuring Weather
What is the instrument used to measure temperature?
Thermometer
Burning your hand on a hot pan is an example of what type of heat transfer?
Conduction
What is another word for water molecules in our atmosphere?
Water Vapor
What is the process of when liquid water changes into a gas?
Evaporation
When water vapor turns directly into a solid- what forms?
Snow
What instrument is used to measure air temperature?
Barometer
This is the type of heat transfer through open space.
Radiation
What is the amount of water vapor in the air
Humidity
When water vapor condenses into a liquid, what forms?
Clouds
A large body of air with similar properties, such as temperature and water vapor
Air Mass
What tool tells us what direction the wind is coming from?
Wind Vane
These types of winds blow from a specific direction and almost always cover longer distances than local winds
Global Winds
What type of cloud is grey at the bottom and brings thunderstorms?
Cumulonimbus
Where does precipitation come from? Give one example of precipitation.
Clouds, rain.
What is the measure of the force of air pressing down on the earth’s surface
Air Pressure
What instrument is used to measure the speed or strength of the wind?
Anemometer
Convection
What are the three main types of clouds?
Cumulus, Stratus, Cirrus
What are the three main steps of the water cycle?
Evaporation, Condensation, Precipitation.
What happens when the atmosphere is saturated?
Clouds form, the humidity is high, we see precipitation
If air pressure is low, what type of weather would we experience?
Lousy Weather- clouds and rain
Process in which carbon dioxide and other gases in the atmosphere absorb infrared radiation from the sun, forming a “heat blanket” around the Earth
Greenhouse Effect
If the humidity is high- what type of conditions would we experience?
The air would feel hot and sticky. It might rain.
What is transpiration?
When plants give off water vapor into the atmosphere.
Heat, Air Pressure, Wind, Moisture
