Properties
What is the top two most abundant gases in the air with their quantity?
What are nitrogen (78%) and oxygen (21%)?
The second layer that contains the ozone layer that absorbs much of the harmful ultraviolet (UV) radiation from the sun.
What is the stratosphere?
Puffy, white, fair weather clouds.
What are cumulus?
When a cold air mass overtakes a warm air mass. Shown by a blue line with blue triangles pointing in the direction the cold air is moving.
What is a cold front?
What do hurricanes feed on?
What is Warm tropical water?
How air pressure changes going up in the atmosphere.
What is as altitude increases, air pressure decreases?
The lowest layer, so it is the most dense air and has the highest air pressure. This is where all weather and most clouds occur.
What is the troposphere?
Layered clouds that can carry light rain and drizzle.
What is stratus?
When a warm air mass overtakes a cold air mass. Show on a weather map by a red line with red half-circles showing the direction of movement of the warm air.
What is a warm front?
What is a thunderstorm?
How air density changes going up in the atmosphere.
What is as altitude increases, air density decreases?
The 3rd layer up, where most meteoroids burn up by friction with the air and become meteors (also called shooting stars).
What is the mesosphere?
The highest clouds that appear thin and wispy, like brushed by an artist.
What is cirrus?
Cold and warm air masses meet, but neither can move the other, creating a "stalemate." Shown by alternating red half-circles and blue triangles on a weather map. Can stall out and bring much rain over a few days where it happens.
What is a stationary front?
The effect that makes ocean currents and winds turn as they move across the Earth's surface and that is due to the Earth's rotation. These turn clockwise in the Northern Hemisphere, and counterclockwise in the Southern Hemisphere.
What is the Coriolis Effect?
What are differences in Air pressure caused by?
What is unequal heating of the Earth's Atmosphere by the sun?
The 4th layer up that deflects some of the sun's energy and causes the northern lights, or aurora borealis.
What is the ionosphere (or thermosphere)?
Layered, dark clouds that carry much water and that are a sign of rainy, maybe stormy weather.
What is nimbostratus?
When a cold front overtakes a warm front, trapping warm air in between two cold air masses. Often happens in snow storms in the Northern U.S. Shown in purple on weather maps, with alternating purple triangles and half-circles on the same side of the purple line.
What is an occluded front?
What is the instrument that measures wind speed?
What is anemometer?
Near a large body of water, 1) the wind pattern during the day and 2) the wind pattern at night.
What is 1) a sea breeze and 2) a land breeze?
The highest layer of the atmosphere that is the boundary with outer space. Communications satellites orbit here.
What is the exosphere?
A convection updraft causes these clouds to rise up very high into the atmosphere, making them the tallest clouds. They contain much energy, and are the producers of thunderstorms.
What is cumulonimbus?
What is the type of Airmass that is wet and cold?
What is Maritime Polar Airmass?
What is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere, we called ....
What is greenhouse effect?
