Study Guide to study for TOMORROW Test

Define, "Air Pressure" the weight of air as it presses down
Define, "Atmosphere" a layer of gases surrounding Earth
Define, "Troposphere" lowest layer of the atmosphere it starts at sea level.
Define, "Stratosphere" the second layer of the atmosphere which keeps the sun's harmful rays from harming the Earth
Define, "Mesosphere" the third layer of the atmosphere the coldest temperatures of the atmosphere are found here
Define, "Thermosphere" top layer of the atmosphere space begins at the top of this layer
Define, "Greenhouse Effect" the process by which heat from the Sun builds up near Earth's surface and is trapped there by Earth's atmosphere
Define, "Weather" the conditions of the atmosphere at a certain place and time
Define, "Nitrogen" a gas that makes up the largest portion of air plans need it to grow
Define, "Oxygen" the second most common gas in the air we need it to breathe
Define, "Carbon Dioxide" a colorless odorless gas that helps hold heat to the Earth
Evaporation is the... first part of the water cycle and the change of state from a liquid to a gas caused by the sun or heat
Condensation is the... second part of the water cycle and the change of state from a gas to a liquid
Precipitation is the... last part of the water cycle and its any type of form of water that fall from the clouds to Earth's surface
Define, "Water cycle" the movement of water into the air as water vapor and back to Earth's surface as precipitation.
Define, "Water Vapor" water in a gas form
What is a stratus? Stratus is a cloud that stays at a low level and forms layered it usually means steady rain
What is a cumulus? Cumulus is a cloud which is fluffy and fave flat bases usually means OK weather and forms low in the sky
What is a cirrus? A thin feathery cloud made of ice crystals and they form high in the sky
What is a cumulonimbus? A cloud that brings thunderstorms
Define, "Air mass" a large body of air that has the same temperature, air pressure, and moisture throughout
Define, "Front" the place where two air masses meet
Define, "Humidity" the amount of water vapor in the air
What does a thermometer do? measures temperature in degrees Celsius or degrees Farenheit
What does a rain gauge do? measures the amount of precipitation that has fallen in an area
What does an anemometer do? measures the speed of wind
What does a barometer do? measures air pressure
What gases are the air made of? Nitrogen, oxygen, etc.
The Troposphere is... The first layer of the atmosphere and it starts at sea level. Where we live on the ground.
The Stratosphere is... The second layer of the atmosphere. the Sun's powerful rays heat up this layer.
The Mesosphere is... The third layer of the atmosphere the coldest temperatures of the atmosphere are here.
The Thermosphere is... The fourth layer of the atmosphere and space begins at the top of this layer.
What are the three main factors that affect climate? Altitude, latitude and bodies of water.
Hurricanes can... Produce floods and strong winds. Along with, destroying houses and get people in danger.
When a cold front moves in... Thunderstorms are being created.
Evaporation is... The first part of the water cycle and water gets heated up and forms clouds.
Condensation is... When the clouds form eventually the water vapor or clouds turns back into water.
Precipitation is... Finally, the clouds get so heavy it uses the bathroom and empty's out it's bladder leaving us with either rain, sleet, hail, or snow.
