Earth's Atmosphere
These are the two main gases in Earth's atmosphere
What are nitrogen and oxygen?
Air masses formed near the poles have this term in their name, meaning cold.
What is polar?
This is the information always found on the top left side of the main circle.
What is temperature?
This instrument measures the amount of precipitation.
A red line with half circles on a weather map means this type of front is occurring.
What is a warm front?
This is the layer of the atmosphere where weather occurs.
What is the troposphere?
Air masses formed near the equator have this term in their name, meaning warm.
What is tropical?
This is the information always found by looking at how much of the main circle is shaded in.
What is cloud coverage?
This instrument measures temperature.
What is a thermometer?
A purple line with triangles and half circles on the same side of the line means this type of front is occurring.
What is an occluded front?
This is the layer of the atmosphere where ozone is.
What is the stratosphere?
An air mass made up of dry cold air has this name.
What is continental polar?
This is the information always found on the top right side of the main circle.
What is the barometric pressure?
This instrument measures air pressure.
What is a barometer?
This type of front is when a warm air mass meets a cold air mass and they both stop moving.
What is a stationary front?
These are the two sections that the thermosphere is divided into.
What are the Ionosphere and Exosphere?
An air mass made of wet warm air is named this.
What is Maritime Tropical?
A tail on a weather station model that has two and a half bars means the wind is blowing this fast.
This instrument measures wind speed.
What is an anemometer?
Areas on a map with an "H" most likely means this type of weather is occurring.
What is fair or mild weather?
These are the four main layers of the atmosphere from Earth moving out to space.
Air masses are only classified as an air mass when these two things are the same throughout the whole body of air.
What are temperature and moisture level?
The temperature where water vapor in the air condenses into water droplets is called this.
What is the dew point?
This instrument measures relative humidity.
What is a hygrometer?
This type of pressure is due to rising, moist air.
What is low pressure?
