Name: Pd. Date: How the Earth Was Made: Asteroids While watching the movie video Asteroids, answer the follow questions. # Question 1 What could fit into the meteor crater in Arizona? 2 3 4 5 What was different about the rocks that were later found that caused Barringer to question a volcanic origin of the crater? What was another important clue Barringer found surrounding the crater that led him to believe it was a meteor crater? (There are 2.) What type of rock had been altered by the impact and was the clue needed to determine it was an asteroid impact? How long ago do scientists believe the impact occurred? 6 How far away were fragments from the impact/shock wave found? 7 What rock clues did they find that implied the metals in the rock at Sudbury, Canada were caused by a meteor impact? What mineral do they find that is rare on Earth but abundant in space and associated with meteors? Where might pieces of the Sudbury impact be found? 8 9 10 What newer technology are scientists now using to locate meteor impacts? 11 What is the black mat layer made of that was found in the Sheridan Cave in Ohio? 12 What hit Jupiter that helped scientists understand how asteroid impacts affect Earth? 13 About how often could a Tunguska sized asteroid hit Earth? 14 How did scientists know they had found parts of meteorites in the Arizona desert? 15 What is the region of debris that remains between Mars and Jupiter? 16 What important finding was made in the meteorites from Murchison, Australia?
