PLAY
weather
The condition of the atmosphere at a specific time and place
meteorology
The study of weather
water cycle
The continuous process by which water moves from Earth's surface to the atmosphere and back.
evaporation
The process by which water changes from liquid form to an atmospheric gas.
condensation
The process by which a gas changes into a liquid, usually due to a cooling of the gas. When this happens in the atmosphere clouds are formed.
precipitation
Any form of water that falls from clouds and reaches Earth's surface (rain, snow, sleet, and hail).
humidity
The amount of water vapor in the air
relative humidity
The comparison of the actual amount of water vapor to the amount of water vapor that would be in the air if it saturated.
saturated
In weather, this refers to the maximum amount of water vapor the air can contain.
dew point
The temperature at which condensation begins
cloud
A collection of small water droplets or ice crystals suspended in the air, which forms when the air is cooled and condensation occurs.
cumulus
Clouds that look like a fluff of cotton, these form close to the ground, and are associated with good weather.
stratus
Dark gray sheets, these clouds form close to the ground often blocking out the sun. Sometimes they bringing light rain or snow showers (then they are referred to as nimbostratus).
cirrus
High-altitude clouds that are thin, feathery tufts of ice crystals.
nimbus
Clouds associated with rain or snow (include several cloud types such as nimbostratus, or cumulonimbus).
transpiration
Loss of water vapor from the leaves of a plant.
