Statement 1: Meteors are known as shooting stars, although they are not stars.
Statement 2: Meteors are small objects, which enter the earth's atmosphere at high speed, heat up due to friction, glow and then evaporate quickly.

The correct option is A Both the statements are true and Statement 2 is the correct explanation of statement 1.
Stars produce heat and light of their own, by virtue of nuclear reactions which take place at their core.
Meteors appear as bright streaks of light in the sky. They are small objects that enter the Earth's atmosphere at high speed and are heated up due to the friction offered by the Earth's atmosphere, as a result of which it quickly glows and evaporates. So, for a very short time the bright streaks last. Some meteors are large and can reach the earth before they completely evaporate and the body that reaches the earth is called a meteorite.
