O'Hare Air
Although we cannot see it, air is made up of this
What is Matter
A prediction of what the weather will be like; made by collecting data about the state of the atmosphere in a given place
What is a Forecast
A large body of air that has similar temperature, pressure and moisture (humidity) throughout; can be as large as continents
What is an Air Mass
The rising of warm, less dense water, and the sinking of cool, more dense water
What are Convection Currents
Measures temperature
What is Thermometer
This phenomena creates air pressure
What is Earth's gravity
The description of the atmospheric conditions in a region at a specific point in time
What is Weather
Amount of water vapor or moisture content in the air
What is Humidity
Dissolved salt content of a body of water; affects density
What is Salinity
Measures air pressure
What is Barometer
Because air is made up of atoms, we can measure how much "stuff" it is made of and how much space it takes up
What is Mass and Volume
The average pattern of weather over a period of time
What is Climate
The force exerted on Earth’s surface by the particles of gas in the atmosphere
What is Air Pressure
These two measurements are the driving factors behind ocean currents
What is Temperature and Salinity
Measures wind speed
What is Anemometer
More air in a region creates this, and less air in a region creates that
What is High and Low pressure system
The main difference between weather and climate
What is Measure of Time
Boundaries between air masses; zones of transition. There are four kinds of these, but we have only focused on two
What are Fronts
The energy transferred by deep ocean currents
What is Thermal Energy
Measures the amount of moisture in the air; humidity
What is Hygrometer
High pressure is associated with this kind of weather
What is Good weather
Dry region on the side of a mountain that is sheltered from the wind
What is Rain Shadow
A fast-moving current of air found high in the atmosphere; play a role in the movement of huge air masses
What is a Jet Stream
The major deep ocean current that transports energy from the tropics to the poles
What is Thermohaline circulation
Measures wind direction
What is Wind Vane
