| Question | Answer |
|---|---|
| Describe the Differences between the sufaces of inner planets versus Outer Planets? | Inner planets have rocky surfaces Outer planets are much larger and are gas Giants |
| How does the mass of Charon compare to Plutos and Earth's masses? | Charon and Plutos have solid surfaces and masses much less than Earth. |
| What is a meteor? | A chunk of rock or dust in space. A streak of light in the sky produces by the burning of a merioroid in Earths atmosphere |
| How is a meteor different from comet? | A meteor is chunk of rock or dust in space. A comets are large chunks of ice and dust like a dirty snowball. |
| What is a Heliocentric System? | A description of the solar system in which all of the planets revolve around the sun |
| What is a geocentric System? | A description of the solar system in which all the planets revolve around the Earth |
| Which famous astronomer explained that the Sun is the center of the system of Planets (solar system)? | Nicholas Copernicus |
| How did Galileo help the heiocentric system gain support? | He saw four moons revolving around Jupiter and that Venus' moon went through phases similar to Earth and therefore Earth could not be at the center of the system of planets |
| What two factors combine to keep the planets in orbit around the Sun? | Inertia and Gravity |
| Which term refers to the tendency of a moving object to continue moving in a straight line or a stationary object to remain in place | Inertia |
| Scientist believe there is enough fuel in the sun to last for about how many more years? | 5 billion more years |
| What layer of the Sun are you looking at when you look at a photograph of the sun? | Photosphere |
| What is the solar wind and which layer of the Sun produces it? | Solar wind is produced by the Corona layer of the sun and send out a stream of electrically charged particles called solar wind |
| How do sunspots on the sun compare to the area around them? | They are cooler than the gases around them |
| What is a solar prominence? | Reddish loops of gas that link different parts of sunspot regions |
| What solar feature can increase the solar wind, sometimes causing electrical power problems on Earth? | Solar Flares |
| What characteristics do all the inner planets have in common | Surface is hot enough to melt lead. The atmosphere is almost entirely leaked away. Are small and have rocky surfaces |
| What characteristic makes Earth unique among the other planets in the solar system | No other planet has Oceans |
| In what ways are Venus and Earth alike | Similar in Size. Density and internal structure are the same. |
| In what ways are Venus and Earth different? | Venus temperature is hotter and has no water or life |
| Explain why the atmospheres of the outer planets cannot escape into space? | Because they have so much mass and exert stronger gravity |
| What characteristics do the outer planets have in common? | They are gas giants Have large atospheres - more mass and gravity and have solid cores |
| What are Saturn's rings composed of? | Ice and Rock |
| How is Uranus different than most other planets | Rotates on a tilted axis |
| Which planet has 4 moons named Europa, Callisto, Ganymede, and lo? | Jupiter |
| What shape are the orbits of comets seen from Earth? | eclipses |
| Where is the asteroid belt located? | Between Mars and Jupiter |
| Where do meteroids usually come from? | Comets or Astroids |
| What happens when a meteroid enters Earth's atmosphere? | Friction makes it burn up and produce the streak of light in the sky |
