KEY 6th Grade Science 1st 9 weeks Test Review Our Solar System: Vocabulary: gravity, comet, meteorite, meteor, asteroid, meteoroid, rotation, revolution, year, day, tides meteroids 1. Chunks of metal or stone that orbit the sun freely, not in a group. Comets 2. Balls of dusty ice that have a tail and orbit the sun freely. Their tails can be millions of miles long. meteors 3. Pieces of metal or stone that fall through the Earth's atmosphere and burn up. The burning material is often called a "shooting star". gravity 4. The force of attraction between objects. This causes the planets and other space objects to maintain their elliptical orbit around the sun. 5. Space object made of rock, metal or a asteroid combination of the two. Most lie in a belt between Mars and Jupiter and can be quite large. 6. Pieces of metal or stone that hit the Meteorites Earth's surface. 7. The amount of time it takes the Earth to 1 year or 365 days revolve around the sun 1 time revolve 8. To orbit or move around another object. 1 day or 24 hours 9. The amount of time it takes for the Earth to spin one time on its axis. Rotate 10. To spin on an axis 11. The gravitational pull of the moon on the tides Earth’s oceans and other bodies of water.
