Question | Answer |
This is the this layer of air that surrounds the Earth | Atmosphere |
These are the particles of air that press down on a surface | Air Pressure |
Earth's atmosphere is divided into 4 layers. Which one is closest to the Earth? | Troposphere |
This layer contains most of the atmosphere's ozone. Airplanes fly above this layer to be above bad weather. | Stratosphere |
What are the 4 layers of the atmosphere? | Troposphere, Stratospher, Mesosphere & Thermosphere |
How does air pressure change with height? | The air pressure gets less the higher you go. The air particles become further apart and less heavy. |
This keeps most of the heat from the sun escaping back into space. | Greenhouse Effect |
This is a large body of air that move over the Earth's surface and slowly changes | Air Mass |
This is what you get when two air masses meet. | A Front |
How does a cold front form? | It forms when a cold air mass catches up to a warm air mass. It forces the warm air mass up into the atmosphere. As it is pushed upwards it cools and that is where thunderstorms are often formed. |
You would use this to measure air pressure. | Barometer |
This is the amount of water vapor in the air | Humidity |
There are fourt types of clouds. Which ones are made up of ice crystals? Winds stretch them into long whispy horsetail shapes. | Cirrus |
These clouds are puffy cotton-ball clouds and begin to form when water dropslets condense at middle altitudes | Cumulus |
You will probably see these clouds when a cold front moves past. They are dark with a grey-white halo. If you see these, it will probably rain soon. | Cumulonibus |
These clouds appear on a grey cloudy day. They can occur on a warm front and will sometimes bring light rain or snow showers. | Stratus |
This is a tool to measure moisture in the air | Hygrometer |
