atmosphere

the air surrounding Earth, made up of 5 layers

‍exosphere

the outermost layer of the Earth's atmosphere starting 300 miles above the Earth

‍mesosphere

this is the third layer of the Earth's atmosphere that is very cold, begins about 50 miles above the Earth's surface

‍stratosphere

the second layer of the earth's atmosphere where most of the airplane fly, starts about 10 miles above the surface to

‍thermosphere

the fourth layer of the Earth's atmosphere, here the temperature rises and burns up many of the items entering the Earth's atmosphere

‍troposphere

the layer of the atmosphere closest to the Earth's surface where weather occurs, starts at the Earth's surface and goes up about 10 miles.

clouds



‍cirrus

Found at the highest levels of the atmosphere, made of ice crystals and means fair (good) weather

‍stratus

are low, gray clouds that blanket the earth and usually bring rain or snow

‍cumulus

are puffy, fluffy white looking clouds, found in the lower to middle level of the atmosphere and usually means Fair (sunny) weather

‍cumulonimbus

also know as thunderheads these clouds can reach high into the sky, are very unstable,

water cycle



‍evaporation

water that is heated by the sun and is changed from a liquid to a gas (WATER VAPOR- invisible water in the form of a gas in the air)

‍condesation

when the water vapor is cooled and changed back from a gas to a liquid

‍cloud formation

dust particles and water droplets or ice crystals that rise into the air to make a cloud

‍precipitation

water in the form of rain, snow, sleet, dew or hail that falls back to earth

‍accumulation

the pooling of water in lakes, rivers, streams or oceans so that the water cycle can start over again

tools



‍thermometer

an instrument that is used to measure hot hot or cold the air is around you

‍windsock/weather vane

an instrument that is used to measure the direction the wind is blowing

‍rain gauge

an instrument that is used to measure the amount of rain during a specific duration of time

‍anemometer

an instrument that is used to measure wind speed

‍barometer

an instrument used to measure air pressure (the force of the air pressing down on the Earth)

severe weather



‍blizzard

fierce winter storms with powerful winds, blinding snow and freezing temperatures with less than a quater mile visibility

‍drought

far less rain than normal over a long period of time

‍lightning

bits of ice & water that bump into each other, building up a tremendous charge of electricity that can flash between the clouds and earth

‍thunder

the quick expansion of air after the lightning hits that causes a loud BOOM!, the sound we call thunder

‍tornado(twister)

can be some of the most powerful winds on the earth that form when a cool, dry air mass pushes against a warm, wet mass of air. The warm air rises and that inrushing of air also rises. It begins to circle forming the funnel and can reach speeds as high as 300 mph.

‍hurricane

huge swirling, spiral storms that form over the oceans and re measured in strength by categories 1 through 5, one is the weakest with winds of 77+ mph and fice is the strongest with winds in excess of 200 mph

‍waterspout

forms mostly in tropical water when a tornado passes over water, draws up wter from the surface forming a pillar of water that may reach over 100 ft.

‍typhoon

a hurricane occuring in the western Pacific usually occurs from July to October

‍monsoon

rain that occurs for months at a time with quite a bit of damage

‍thunderstorm

made uo of falling rain, flashing lightning and roaring thunder usually beginning in cumulonimbus clouds

changing seasons



‍lake effect

when the air over a body of water holds moisture and the winds blow onto the nearby land causing cooler temperatures during the summer and warmer, wetter times during the winter
