A meteor is
- Aa rapidly moving star
- Ba piece of matter which has entered the earth’s atmosphere from outer spaceCorrect
- Cpart of a constellation
- Da comet without a tail
Explanation
The correct answer is B because a meteor is a fragment of rock or metal from space, such as an asteroid or comet remains, that enters the Earths atmosphere. As it travels at high speeds, friction with the air creates intense heat, causing the object to glow and create a streak of light often called a shooting star. If the object burns up completely in the atmosphere, it is a meteor; if it survives the heat and hits the ground, it is called a meteorite. Options A, C, and D are incorrect because stars and constellations are distant celestial bodies, and a meteor is a physical fragment rather than a type of comet.
