Most meteors that fall into the Earth's atmosphere burn up before reaching
the ground. Why is this?
A. The sound waves are building up in front of the meteorite because
of its speed, and these vibrations shake the meteor apart.
O B. They are hitting air molecules at a high speed and breaking them
apart, which produces a lot of heat.
C. The meteorites create sonic booms that cause them to implode.
D. They are usually hit by lasers from defense flights.
