|---|---|
| Heat from a campfire reaches you by | radiation |
| winds are caused by differences in | air pressure |
| lcal winds differ from global winds because they | are caused by unequal heating within a small area |
| on average, a snowfall of 20 centimeters would equal a rainfall of | 2 centimeters |
| convection takes place because | cold air is more dense than warm air |
| the freezing point of pure water on the celsius scale is | 0 degrees Celcius |
| Relative humitdity can be measure with a | psychrometer |
| land breezes occur because | land cools off faster than water |
| clouds form when water vapor in the air | become liquid water or ice crystals |
| Earth's rotation makes wind seem to curve. This is called the | Coriolis effect |
| Large clouds that often produce thunderstorms are called | cumulonimbus clouds |
| very high feathery clouds are called | cirrus clouds |
| layered louds that often cover much of the sky are called | stratus clouds |
| the difference between sleet and hail is | the size of the ice pellets and where the ice pellets are formed. |
| heat transfer between two substances that are in contact is called | conduction |
| global winds generally | blow from specific directions over long distances. |
| any form of water that falls from clouds is called | precipitation |
| wind spped is measured by a | anemometer |
| local winds blow over _______distances than global winds | shorter |
| fluids like air tne d to move towards area of _____ pressure | low |
| water vapor in the atmosphere that condenses and falles to the earth is measured with a | rain gauge |
| when you touch a hot spoon, heat is transferred by ___________ from the spoon to your hand. | conduction |
| earth's major wind belts are the trade winds, the prevailing westerlies, andthe polar ___________ | escterlies |
| an instrument called a _______________ is used to mesaure how hot or cold the air is | themometer |
| most of the heating of the troposphere occurs by ___________, which is the transfer of heat by fluid movement. | convection |
| if 4 grams of water vapor are present in a cubic meter of air that can hold a maximum of 10 grams, the __________________ is 40 percent | relative humidity |
| uneven heating of the atmosphere leads to difference in air ________, which causes wind. | pressure |
| icreased cooling called the _______________ factor can make the air feel cooler than the measurement on a themometer. | windshield |
| a sea breeze is a type of ________ wind | local |
| winds that blow between the equator and the poles are ___________ winds. | prevaling |
| winds in the mid-latitudes that blow from west to east are called ____________ | westerlies. |
| clouds form when water vapor in the air become liquid water in the process called | consendation |
| the ___________ is the temperature at which water in air changes from a gas to a liquid | dewpoing |
| clouds that fomr near the ground an look like fluff heaps of cotton are called | cumulus |
| flat layered ____________ clouds can cover most of the sky | nimbostratus |
| an ice pelled larger than 5 millimeteres in diameter that forms during a thunderstorm is cxalled a | stratus cloud |
