  1. Sun & Earth: Earth rotates on a tilted axis & orbits the Sun! MRS. GIANELOSLesson 2.1 SPACE SCIENCEGRADE 8

  2. What you will learn today… • What causes day & night? • What percent of the earth is always lit by the sun? • How many days does it take for the Earth to revolve around the sun? • Why do we have seasons? • What is an Equinox and Solstice?

  3. The Earth Rotates: • turns on its imaginary axis counterclockwise every 24 hours or 1 day,AXIS OF ROTATION =23 degreesPoles are end of axis, equator is halfway Sun shines on one side of Earth only *LIGHT side is DAY *Dark side is NIGHT| night moves west

  4. LET’S REVIEW • The rotation of the Earth on its axis causes- • A days • B months • C seasons • D yearsWhat is rotation? (define)http://www.cs.sbcc.cc.ca.us/~physics/flash/LengthofDay.swf

  5. Rotation causes day & night. • Rotation is the turning or spinning of the Earth in one place on its imaginary axis. • Rotation of the earth on its axis causes day & night. (answer A).

  6. Earth’s tilted axis & orbit cause seasons. SEASONS: patterns of temperature change and other weather trends over a year SEASONS OCCUR BECAUSE:**the amount of sunlight hitting an area changes because of Earth’s tilt

  7. Which of these is caused by the turning of the Earth? • F Summer and winter • G Stars • H Day and night • J Moon phases

  8. Earth Science Question: A • Which of these shows the location of a polar ice cap? • Which of these shows the location of the equator? B C C D

  9. The revolution of the Earth around the sun • Takes 365 days or one year. Due to the tilt of the Earth’s axis during revolution, the Earth experiences seasons.Earth’s orbit is close to a circle shape http://esminfo.prenhall.com/science/geoanimations/animations/01_EarthSun_E2.html

  10. The revolution of the Earth around the Sun takes- • A a day & night or 12 hours • B a week or 7 days • C a month or 29-31 days • D a year or 365 days

  11. Seasons Equinox: sunlight shines evenly on Northern & Southern HemispheresSolstice: area of sunlight is at it’s maximum in one of the hemispheres
