  1. Astronomy Review

  2. Match the features on the left with the shapes on the right to show relative size. The “diamond” shape would be the largest feature and the “triangle” would represent the smallest feature. • Galaxy • Solar System • Earth • Universe

  3. How old is the……. Universe?

  4. How old is the……. Solar system?

  5. Age of Universe? • NASA says……..12 – 14 billion years • Wikipedia says……13.75 + or - .11 billion

  6. Age of Solar System? • NASA says……..4.5 billion years • Wikipedia says……4.6 billion

  7. What’s a Solar System? • the sun with the celestial bodies that revolve around it in its gravitationalfield….wordnetweb.princeton.edu/perl/webwn • The Solar System consists of the Sun and those celestial objects bound to it by gravity, all of which formed from the collapse of a giant molecular cloud approximately 4.6 billion years ago. ...en.wikipedia.org/wiki/Solar_System

  8. Moon PhasesBased on Sun, Moon, & Earth Position Be able to determine Moon phase based upon the alignment of the Earth, Moon, and Sun

  9. Moon PhasesAs seen from Earth Be able to recognize the Moon phases as seen from Earth.

  10. EclipsesBased on Earth, Sun, Moon Location How do Partial and Total eclipses differ?

  11. Moon Changes in Daily Altitude Why does the Moon’s altitude change each day?

  12. Moon’s affect on Tides What’s the relationship between Moon phases and Spring and Neap tides?

  13. Orbital speeds and Gravity Planets and other objects travel faster when closer (Perihelion) to the Sun and slower when further away (Apehelion) in their orbits.

  14. Reasons for the Seasons •The Earth is tilted •Parallelism of Earth’s axis •The Earth revolves around the Sun

  15. Foucault Pendulum Proof that the Earth rotates.

  16. Insolation INSOLATION = Incoming Solar Radiation What affects insolation?

  17. Length of Daylight Hours Length of daylight varies based on latitude. Why does the length of daylight vary at different latitudes?

  18. Angle of Insolation How does the angle of insolation affect temperature?

  19. Changes in Sun Zenith Altitude for Each Season Why does the Sun’s altitude change throughout the course of a year? What causes the change in the Sun’s altitude throughout the year?

  20. Star Evolution Understand that stars can evolve differently.

  21. H-R Diagram How are H-R diagrams produced? What do H-R diagrams measure? Where does the Sun fit into the H-R diagram?

  22. Electromagnetic Spectrum What’s the source of this energy?

  23. Doppler Effect Red Shift Blue Shift
