-
Layer of gases that surround the Earth (Earth's blanket)
Atmosphere
-
precipitation - rain freezes on its way to the ground
sleet
-
layer of atmosphere closest to Earth's surface (weather occurs there)
Troposphere (tornado is weather)
-
precipitation made in clouds by water vapor freezing into ice crystals
snow
-
cloud that brings thunderstorms
cumulonimbus
-
high, thin, feathery cloud during fair weather
cirrus
-
object forms his in sky when water vapor begins to condense
cloud
-
cloud that is low and fluffy brings fair weather
cumulus
-
cloud that is low and layered and brings rain
stratus
-
part of atmosphere above the weather, jet planes fly there and it protects from the Sun's ray.
stratosphere
-
atmosphere part closest to space
thermosphere
-
type of water that falls from the clouds to the Earth's surface
precipitation
-
layer of atmosphere that helps protect us from meteors
mesosphere (meteors)
-
precipitation that is liquid water
rain
-
precipitation that is drops of rain in clouds that freeze, then blows upwards until to heavy and then fall to the Earth
Hail
-
large body of air with same temperature, air pressure and moisture throughout.
air mass
-
average weather conditions over an area for long period of time
climate
-
place where two air masses meet
front
-
climate that has warm, dry summers and cold, wet winters. (temps change a lot)
temperate climate
-
climate almost always hot and rainy
tropical climate
-
climate that has cold temp throughout most of the year (think about polar bears)
polar climate
-
Factors affecting climate: (3)
- altitude (how high up)
- oceans
- latitude (amount of sunlight)
-
Factors of weather (4)
- wind
- humidity
- air pressure
- temperature
-
measures wind speed
anememeter
-
measures wind direction
weather vain
-
measures temperature
thermometer
-
measures air pressure
Barometer
-
Measures precipitation
rain gauge
-
Water boils at:
212 F / 100 C
-
when liquid water changes into water vapor (2)
evaporation and boiling
-
condition of the atmosphere at a certain place/time
weather
-
precipitation that seeps below surface of ground
ground water
-
water freezes at:
32 F / 0 C
-
weight of air as it presses down
air pressure
-
2nd most abundant gas in atmosphere
oxygen
-
most abundant gas in atmosphere
nitrogen
-
process where water continually changes from solid to liquid to gas and vice versa
water cycle
-
Water turns from liquid into ice
freezing
-
When heat builds up near Earth's surface and is trapped there by the atmosphere
greenhouse effect
-
water changes from ice to liquid
melting
-
precipitation that flows down hill over the ground into larger bodies of water
runoff
-
layer of gasses that makes Earth's blanket
atmosphere
-
when water vapor changes into liquid water
condensation
