  2. 1 Rotation and Revolution • Standard: Explain how Earth moves in space and changes positions?

  3. Glossary Earth in the Universe Universe • 1) Orbit • 2) Ellipse • 3) Rotation • 4) Revolution • 5) Precession • 6) Perihelion • 7) Aphelion • 8) Terrestrial Planets • 9)Jovian Planets • 10) Nebula • 11) Meteoroid • 12) Meteorite • 13) Astronomy • 14) Solar Eclipse • 15) Lunar Eclipse • 16) Crater • 17) Mare • 18) Rille No New Vocabulary this Week ….. You should have these words from last week. If not … I’ll be re-grading them this week.

  4. Early Astronomy only write down what is underline and bold  Sir Isaac Newton law of universal gravitation  Universal Gravitation Gravitational force decreases with distance. • The greater the mass, the greater gravitational force.

  5. Gravity’s Influence on Orbits

  6. Motions of Earth The Earth–Moon–Sun System • two main motions • 1) rotation • 2) revolution • Precession is a third & very slow motion of Earth’s axis.

  7. Precession

  8. The Earth–Moon–Sun System Rotation turning, or spinning, of a body on its axis. Earth = 24 hours day and night  Revolution motion of a body, along a path around some point in space. Earth = 365 days or 1yr • Perihelion time in January when Earth closest to the sun. • Aphelion time in July when Earth is farthest from the sun.

  9. Activity • You will create a vocabulary picture booklet using the 18 vocabulary words in your glossary. • You need to draw a picture with COLOR for each vocabulary word in your glossary. • You cannot use words in your picture • When you are done you will cut out each picture and staple it together like a booklet.

  10. Vocabulary Words for Booklet • Orbit • Ellipse • Rotation • Revolution • Precession • Perihelion • Aphelion • Terrestrial Plants • Jovian Planets • Nebula • Meteoroid • Meteorite • Astronomy • Solar Eclipse • Lunar Eclipse • Crater • Mare • Rille
