151. Question:

152. –How does the energy (height of drop) and mass of the meteorite effect the crater?

153. 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 _____.

154. 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.

155. Answer: –Large meteorites will often have more damage potential

156. Answer: –Large meteorites will often have more damage potential than smaller ones.
