Question 21

Why do evidences of asteroids hitting the Earth so hard to find?
  1. Weathering, erosion, and deposition on Earth’s surface have destroyed most impact craters.
  2. They do not strike fast enough to create impact craters.
  3. They are not big enough to leave impact craters.
  4. They are made mostly of frozen water and gases and are vaporized on impact.
