science

TermDefinition
WEATHER DYNAMICS the study of how the motion of water and air causes weather patterns; air pressure and ocean currents are two examples of weather dynamics
WEATHER the conditions outside considered from day to day; compare with climate
STRATUS CLOUDS clouds with a flattened, layered shape; usually indicate stable weather.
RADIATION the transfer of energy by means of waves that do not require a medium.
OROGRAPHIC CLOUDS clouds that form when air moves up a mountain, expands at the lower pressure, and cools.
HEAT COMPACITY the measure of how much heat a substance requires to increase its temp or how much heat it releases as its temp decreases.
HEAT SINK any object or material that absorbs energy and becomes warmer; the atmosphere and oceans are examples of heat sinks.
HYDROSPHERE all of earths water both fresh and salt, liquid and ice; the hydrosphere makes up around 70% of earths surface.
FRONTAL CLOUDS clouds that form where the front of a large moving mass of air meets another air mass of a different temp.
CUMULUS CLOUDS clouds with a billowing, rounded shape; usually indicates unstable weather.
CLIMATE weather conditions of an area averaged over many years.
CONVECTIVE CLOUDS clouds formed from convection, that is, when air near the ground absorbs energy from heated surfaces (oceans, lakes, asphalt, concrete, dirt) becomes warmer and less dense and rises in the atmosphere; most clouds are convective.
CONDUCTION the transfer of energy through the collision of particles.
CONVECTION the verticle transfer of energy by the movement of particles in a fluid.
ELECTROMAGNETIC SPECTRUM the set of waves that can travel through empty space at the speed of light.
ADVECTION the horizontal transfer of energy by the movement of particles in a fluid.

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.

To see how well you know the information, try the Quiz or Test activity.
