Detailed explanation-1: -Meteoroids are objects in space that range in size from dust grains to small asteroids. Think of them as “space rocks.” When meteoroids enter Earth’s atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors.
Detailed explanation-2: -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.
Detailed explanation-3: -Friction can produce heat. This can be observed if you rub your palms against each other. Likewise, when a meteor enters Earth’s atmosphere, air applies a frictional force (air drag) against its motion. Due to this, heat is produced and the meteor starts burning.
