An asteroid is a rocky object that orbits the sun. A meteoroid is a small rocky object that enters Earth's atmosphere. Many burn up and become visible as meteors, or "shooting stars". Meteorites are objects that survive impact with Earth's surface. The document discusses asteroids, meteoroids, and meteorites, as well as notable impact events like the Tunguska event and Chelyabinsk meteor, and introduces the Torino scale for categorizing impact hazards from near-Earth objects.

- 214. • Question:
- 215. • Question: – How does the energy (height of drop) and mass of the meteorite effect the crater?
- 216. • Answer: – How does the energy (height of drop) and mass of the meteorite effect the crater? – At a ____ drop with the large meteorite, the diameter of the crater was ____. At a ____ drop with the large meteorite was _____.
- 217. • Answer: – How does the energy (height of drop) and mass of the meteorite effect the crater? – At a ____ drop with the large meteorite, the diameter of the crater was ____. At a ____ drop with the large meteorite was _____. – As the energy is increased with speed / height, or with greater mass, the size of the craters diameter, and thus the distance of ejection will increase.
- 218. • Answer: – Large meteorites will often have more damage potential
- 219. • Answer: – Large meteorites will often have more damage potential than smaller ones.
