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.
