• Question:

• Question:– How does the energy (height of drop) and

mass of the meteorite effect the crater?

• 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 _____.

• 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.

• Answer:– Large meteorites will often have more

damage potential

• Answer:– Large meteorites will often have more

damage potential than smaller ones.
