QuestionAnswer
Weather Earth experiences weather because the earth is heated unevenly-ex: heat and cold daily changes
Weather Variables The conditions outside-ex: hot, cloudy pressure humidity
Climate The weather conditions of a certain place-ex: wet, dry over long periods of time
Atmosphere Moves weather on earth-ex: rain envelope of gases that surround the earth ex: oxygen, carbon dioxide, water vapor, and nitrogen
Troposphere Water from the earth's surface and is transported to other regions by the wind-ex: transports to sun layer of atmosphere closest to surface where weather occurs Ex: planes and weather occur in this layer
Lithosphere Water that goes in the ground takes longer to get back in the sky-ex: evaporation
Hydrosphere Includes water-ex: falls on earth to make snow or rain
Altitude The height of where you are at-ex: 50,000 feet above sea level
Precipitation Clouds that rain water out of it-ex: rain
Transpiration Plants roots would absorb the water then goes into the air-ex: goes into the atmosphere when water evaporates from the leaves of plants
Condensation When water turns into clouds-ex: after evaporation in clouds
Evaporation When water goes back into the air-ex: sunny day shrinking puddle on the ground
Runoff This happens when there’s too much water-ex: goes into streams
Air pressure A force that is the result of the weight of a column of air pushing down on an area-ex: the weight of a column of air above is about the same weight of a large bus Ex: High pressure is good weather and no clouds
Barometer Used to measure the atmosphere pressure-ex: weather
Wind Horizontal movement of air parallel to Earth's surface-ex: cold thing blowing
Anemometer Used to measure wind speed-ex: storm
Wind Vane Points into the wind or in the direction the wind is blowing from-ex: blows from the south
Prevailing Winds A series of planetary winds that move in a specific direction most of the time-ex: they can move multiple directions
Jetstream Very strong, predominantly westerly air currents encircling the globe several miles above the earth ​that drive air masses and storm tracks ex: pushes to the west, planes take a longer time from that direction This is because earth is heated unevenly
High Pressure Area Winds that spin clockwise and outward from the center-ex: dry, clear weather, happy weather, precipitation can occur only in front of the warm front, cool air is sinking, more dense High to Low Pressure
Low Pressure Area Winds that spin counterclockwise in northern hemisphere-ex: clouds, precipitation, storms, is a cold front with lousy weather, precipitation can only happen behind, warm air rises, less dense, clouds
Air Mass A large body of air in the lower Troposphere that has similar temperature, humidity and air pressure to the part of Earth surface that it developed over-ex: hot, cold
Continental Polar Air Mass An area on land that produces cold, dry air masses-ex: cold front
Continental Tropical Air Mass An area on land that produces hot, dry air masses-ex: warm front
Maritime Polar Air Mass An area on water that produces cool and moist air masses-ex: cold front
Maritime Tropical Air Mass An area on water that produces warm and moist air masses-ex: warm front
Fronts The place where two fronts meet-ex: cold and warm front
Warm Front Moves cold air away from its place-ex: low pressure, some precipitation in the front of it Circle
Cold Front Moves to a region that has warm air-ex: high pressure, storms inside of it Teeth
How could you use an isobar map to predict wind speed and direction? Closely spaced isobars indicates winds to increase. Father spaced isobars indicates winds to decrease.
Isobars An imaginary line or a line on a map or chart connecting or marking places of equal barometric pressure
Global winds Winds that move over long distances between the equator and poles

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
