1. At night, when the sky is clear and the moon is not visible we may sometimes see bright streaks of the light in the sky.
2. These are commonly known as shooting stars.
3. They are not stars, they are meteors.
4. A meteor is a small object that occasionally enters the earth’s atmosphere.
5. It has a very high speed.
6. The friction due to atmosphere heats it up.
7. It glows and evaporates quickly.
8. That is why the bright streak lasts for a very short time.
9. Some meteors are large and so they can reach the earth before they evaporate completely.
