Weather and Climate
Question | Answer |
---|---|
two major prerequisites for a hurricane | moisture and heat |
hurricanes obtain their energy from | warm ocean water |
sun’s energy causes warm humid air to rise in an updraft, creating cumulus/cumulonimbus clouds | stage 1 thunderstorm development |
Ice particles may form at the top of the cloud. They fall and pull cold air down, creating a downdraft and heavy rain or hail. | stage 2 thunderstorm development |
storm slows or ends as the downdraft prevents warm air from rising | stage 3 thunderstorm development |
form of oxygen with three oxygen atoms in each molecule | ozone |
causes most of the heating of the atmosphere | convection |
layers of the atmosphere are classified according to | temperature |
process by which gases in the atmosphere absorb and give off infrared radiation | greenhouse effect |
temperature falls and thunderstorms could be likely | cold front |
temperature rises and places are likely to experience no rainfall at all or just a light drizzle | warm front |
air rises and cools; generally produces clouds and rain | low pressure system |
air slowly sinks down and spreads outward; generally produces clear skies and calm air or gentle breezes | high pressure system |
water changes its physical form, but is never | created |
water molecules ___ as the temperature of the water rises | speed up |
water absorbs and releases heat energy more ___ than land does | slowly |
clouds form because water vapor | condenses |
clouds are physically composed of water in the form of | liquid and/or solid |
rising air is cooled to its ___ creating tiny water droplets suspended in the air | dew point |
sunlight warms the surface and evaporates the water | cloud formation step 1 |
warm, moist air builds up in the lower atmosphere | cloud formation step 2 |
rising air currents organize into thermals | cloud formation step 3 |
water vapor in rising air condenses to form cloud water | cloud formation step 4 |
