Which of the following is not a characteristic of meteor showers? a. flashes of light. b. rocky debris. c. falling stars. d. meteorites.

A meteor is what we see in the sky when a meteoroid, comet or asteroid enters the Earth's atmosphere. A meteoroid is a solid rock or metallic body that comes from outer space. When these rocks enter the Earth's atmosphere, they collide with the air molecules in the atmosphere at very high speeds and heat up to extremely high temperatures. This creates the streak of light we see across the sky during a meteor shower.

Therefore, in a meteor shower, we should see streaks of light from the meteoroids burning up in the atmosphere. Rocky debris is also present as these rock bodies are entering the atmosphere and breaking apart due to the high temperatures. When the rock debris from a meteoroid survives entering the atmosphere, it is referred to as a meteorite, which will also be present during a meteor shower. 

The answer is option C. Falling Stars.

There are no actual falling stars during a meteor shower, this is just a term used to describe what a meteor shower looks like, but there are no actual stars involved.
