Phys 107 Astronomy Hauck Chapter 8 1. The four major features in our solar system that provide clues to how it was formed are gases, planets, comets and the sun. 9. Solar wind is consisted of charged particles that are continually blown off the surface of the sun in all directions. 10.Comets and asteroids are the “left overs’ of planets, which shows how planets are formed. They are small planets basically. 11.The heavy bombardment was a period where the vast majority of the collisions occurred during the first few hundred million years of the solar systems history. 12.It is thought that the earth had a giant impact and its pieces began to orbit the earth and came back together to form the moon. 13. Radiometric dating is used to measure the age of a rock, and relies on careful measurement of proportions of various atoms and isotopes. 14.We find the date of the solar system through meteorites that fall to earth. The oldest ones are 4.5 billion years old. 15.Yes, this statement makes sense.
