Atmosphere Bellwork Bellwork 1) Draw and fill in the pie graph: 2) An _________ is a mixture of gases that surrounds a planet 3) ____ _______ is the weight of the air in the atmosphere pressing down on the Earth. 4) _______ keeps our atmosphere and air from drifting out into space Answer Key Atmosphere 79% 20% 1% Air pressure gravity Bellwork 1) In the troposphere, temperature _____with elevation 2) In the stratosphere, temperature ______with elevation 3) The _____layer is found in the stratosphere. 4) The layer that contains 75% of our air and our weather is called is the________. 5) Earth’s atmosphere is divided up into layers that are based upon their _____ 6) Draw the diagram and label each layer with temperature curve Answer Key increases ozone decreases increases troposphere Temperature stratosphere Bellwork 1) Because the earth is round, the earth is heated ________. 2) Solar radiation is strongest or more direct intense at the ______. 3) Solar Radiation is weakest and more indirect at the ______. 4) This creates a temperature imbalance— _____ equator and _______ poles 5) The earth moves heat from the equator to the poles by _______. 6) As a result, our ______ and weather develop Answer Key Cold Wind Unequally Convection Poles Hot equator Bellwork 1) Our atmosphere is made of 21%_____ and 78% _____ 2) Releasing _____ into our atmosphere can destroy the ozone layer. 3) We live in the ____ where all our weather takes place. 4) The _____ is a fast high altitude wind 5) ____% of radiation form the sun is absorbed and ___% is reflected 6) The diagram shows a ______ breeze 7) ___ is a human pollutant Answer Key SMOG oxygen CFC’s Jet stream Ozone Sea land 70% nitrogen troposphere 30% 1) 2) 3) 4) 5) _____ reflects the most light. Uneven cooling and heating rates create _____ & _____ breezes A ___ ______ occurs during the day when air from the ocean moves in over land A ___ ______ occurs at night when air from the land moves towards the ocean Sea breezes and land breezes transfer heat by_______. 6) Fill the table out Ocean Land 8 AM temp 12 PM temp 4 PM temp 8 PM temp Answer Key land Sea snow Sea breeze Land breeze Convection Bellwork 1) 2) 3) 4) 5) 6) Radiation is more ____at the equator and more ____out at the poles, this creates warm temperatures near the ____ and cold temperatures near the____ At the _____hot air rises along the equator Steady winds called the____ move our weather and storms across the Unites States (we live in them) The ______ effect causes our winds to curve or deflect Ozone in the stratosphere is important because it ______ UV radiation Land heats up and cools more quickly than water creating _____ and ____ breezes Answer Key absorbs Equator sea Doldrums Coriolis land direct Poles Westerlies indirect Bellwork 1. Layer _____ contains the space shuttle and is the boundary between space and our atmosphere 2. Layer _____ contains our weather 3. Layer _____ contains the ozone layer 4. Layer_____ causes meteors to burn up. 5. Earth’s atmosphere is divided up into layers that are based upon their _____ 6. Every time you breath, you take in 21 % _____ and 78%______ Answer Bank oxygen Temperature nitrogen Bellwork 1) The ______ is the zone around the equator where hot air rises. 2) The _______ blow from east to west and lie between 0 and 30 degrees latitude. 3) The _______ blow from west to east and lie between 30 and 60 degrees latitude. 4) The _______ blow from east to west and lie between 60 and 90 degrees latitude. 5) The ______ blow our weather across the united states (west to east) Answer Key Cold westerlies Wind doldrums Convection Poles tradewinds easterlies
