  2. Page 1 Day: Tuesday Date: January 27th Time: 12PM-2PM Where: Room TBA Midterm Review Packet …and so is the Midterm Exam, so please study …address conflicts- show schedule

  3. Page 1 Absolute Zero • Temperature where all molecular movement ceases- it is the lack of any energy • Lowest possible temperature ever- only theoretical • -459°F or -273°C or 0 kelvin Moleular Motion

  4. Page 1 The height of an object is above the horizon (expressed in degrees) • Altitude= 90º Altitude 30º 20º 10º 0º

  5. Page 1 • Evaporation= phase change from liquid to gas which requires a gain of 2,260 j/g of energy • Condensation= phase change from gas to liquid which requires a loss of 2,260 j/g of energy • Insolation= incoming solar radiation; Sun’s energy that reaches the Earth’s atmosphere

  6. Page 1 Angle of Insolation • Definition- the angle at which the Sun’s energy strikes the Earth’s surface • Energy from the _______ SUN Equatorial Region New York State Polar Region A B C Which location receives energy with the greatest angle of insolation? Least?

  7. Page 1 Air Mass & Source Region • ____________- a large body of air in the troposphere with similar characteristics of ________________, ___________________ and ______________________ • source region= ________________________________________________________ ________________________ Air mass moisture temperature pressure the geographic region where an air mass forms mT come from Gulf of Mexico & cP come from Central Canada

  8. Page 1 FRONTS a boundary or interface Between 2 different air masses

  9. HOW TIGHTLY PACKED THE ATOMS ARE Page 1 Density

  10. Page 1 Kepler’s 1st Law: Definitions • Eccentricity: is a numerical value used to describe the degree of flatness or “ovalness” of an ellipse • How out of round the shape is • *Eccentricity of a perfect circle= 0 Comet Straight line= 1 Circle= 0

  11. Factors Affecting the Angle and Intensity of Insolation (page 11) • Seasons- as the Earth revolves around the Sun the Sun’s direct rays change between the Tropic of Cancer 23.5° North and • Tropic of Capricorn 23.5° South • Tropic of Capricorn at 23.5° South • on December 21st 2. Equator 0° March 21st and September 23rd 3. Tropic of Cancer at 23.5° North on June 21st
