| the process by which water molecules in liquid water escape into the air as water vapor | evaporation |
| water vapor is also added to air by what | living things |
| water enters the roots of plant,rises to the leaves and releases as what | water vapor |
| respiration | process of breathing |
| persperation | sweating |
| transpiration | giving off vapor thru pores |
| precipitation | any form of water that comes from a cloud |
| Humidity | a measure of the amount of water vapor in the air |
| the amount of water vapor that the air can hold idepends on the what | temperature |
| what kind of air holds the most amount of water vapor | warm air |
| an instument used to measure relative humidity | psychrometer |
| what forms when water vapor in the air becomes liquid water or ice crystals | clouds |
| clouds are not what | water vapor |
| clouds are what | water droplets |
| process when molecules of water vapor become liquid water | condensation |
| cold air holds blank water vapor | less |
| temperture in which condensation begins | dew point |
| clouds are made up of millions of what | ice crystalsand water vapor |
| water vapor needs a solid surface on which to what | condensate |
| solids in the air: | dust,salt,smoke |
| water vapor that condenses from the air onto a cold solid surface is called what | dew |
| frost is ice that has been directly depoisted onto a cold what | surface |
| clouds form when what | cooled |
| dew is not what | percipitation |
| frost is not what | frozen dew |
| our weather comes from the where | west |
| windward is the what side | west side |
| leeward side is the what side | eastern side |
| place where very little rain falls | rain shadow |
| meterologists classify clouds in three main types: | cumulus, stratus,cirrus |
| clouds are also classified in what | altatud |
| cumulus clouds are usually how many kms | 18 |
| cumulus clouds usually indicate what | bad weather |
| nimbo means what | rain |
| cumulonimbus clouds usually produce what kind of clouds | thunderstorms |
| flat clouds are called | stratus |
| srato means what | blanket |
| a srtatus day is an what kind day | overcast |
| wispy and feathery clouds are called what | cirrus |
| what clouds form in high levels | cirrus |
| cirrus clouds are manly made of what | ice crystals |
| part of the cluds name may be based on its what | hieght |
| alto means what | high |
| what two clouds are the main type of these | altocumulus and altosratus |
| what forms after a warm humid day | fog |
| clouds that form near the ground is called what | fog |
| percipitation | any form of water that falls from clouds |
| percipitation always comes from what | cloud |
| not all clouds produce what | percipitation |
| common percipitationis what | rain, snow, hail |
| what is the most common type of percipitation | rain |
| drops of water are called what if they are at least 5 millimetersin diameter | rain |
| percipitation smaller than what it is mist or drizzle | .5 millimeters |
| mist or drizzle usually come from what type of clouds | nimbostratus clouds |
| what forms when raindrops fall through freezing air forming solid particles of ice | sleet |
| freezing rain is called what | icestorms |
| hailis a round pellet of what | ice |
| hailis usually form in what kind fo cloud | cumulonimbus |
| what forms after it goes through levels of the cloud | hail |
| sublimationis the process by which a gas tuns directly to a what | solid |
| water vapor ih a cloud is converted directly to ice crsytals | snow |
| how many sides does a snowflake have | six |
| an open can or tube that measures how much rain has fallen | rain gauge |
| long periods of unusally low percipitation | drought |
| what is the common method of forming rain | cloud seeding |
| chemicals used for cloud seeding | CO2 and silver iodide |
