  1. The force of attraction between any two objects due to their mass
    Gravity
  2. The Sun and the objects that are traveling around it.
    Solar system
  3. A "dirty snowball" orbiting the Sun - a mixture of ice, frozen gases, rock and dust left over from the formation of the solar system.
    Comets
  4. Any of the nine major objects that travel around the Sun and shine by reflecting its light.
    Planets
  5. One of the five planets beyond the asteroid belt (Jupiter, Saturn Uranus, Neptune, Pluto)
    Outer Planets
  6. The tendency of a moving object to keep moving in a straight line or of any object to resist a change in motion.
    Inertia
  7. Patterns formed by groups of stars in the night sky.
    Constellations
  8. Region between Mars and Jupiter where most asteroids are found.
    Asteroid belt
  9. A chunk of rock from space that burns up as it travels through Earth's atmosphere.  A "shooting Star"
    Meteors
  10. A planet between the Sun and the asteroid belt (Mercury, Venus, Earth, Mars)
    Inner planets
  11. A large hot ball of gas that is held together by gravity and gives off it's own light.
    star
  12. What depends on mass of an object and its distance from source
    Gravity
  13. Name the planets in the correct order.
    Which are the inner planets?
    Which are the outer planets?
    • Inner - Mercury, Venus, Earth and Mars
    • Outer  - Jupiter, Saturn, Uranus, Neptune and Pluto
  14. What is the Sun made up of?
    It is composed of mostly hydrogen and helium.  

    The formation of helium from hydrogen is what generates light and heat from the Sun.
  15. Explain how constellations are used to navigate and find a particular star in the night sky.
    The pattern of stars in a constellations always look the same even though the constellations appear to change position during the night and from season to season.  You can tell directions by looking at the constellations and stars
  16. Explain how inertia and gravity keep a planet in orbit.
    Inertia keeps a moving object going in a straight line, without gravity, the planets inertia would keep them moving in a straight line.  Gravity steers the planets in their oval paths around the Sun.
  17. Identify differences and similarities between the planets.
    • The inner planets have solid, rocky crusts and have craters.
    • The gas giants are dense and rocky at the core, but are surrounded by layers of dense liquid.    The gas giants have rings.
    • Mercury, Venus and Earth are geologically active.
  18. Explain why the Sun is important to the solar system.
    The Sun hold the planets in their orbits in the solar system.  It also provides them with light and warmth.  The Sun is the reason for day and night.
  19. Explain what factors allow Earth to have life and why other planets can not.
    Earth is the water planet and has the right temperatures to support life.  Other planets are made of mostly gas and have extreme temperatures.
  20. Which Planet is called the red planets
    Mars
  21. Which planet is the hottest planet?
