Meteor

Meteors are celestial bodies that move at a high velocity entering the earth’s sky. When the meteors move to the Earth’s surface, they cause friction with the Earth’s atmosphere. That friction produces heat, so meteors are  burnt out completely. But there are also meteors that are not burnt out so they can reach the Earth’s surface. When a meteor is burnt it will look like a beam of flashlight, so it is often called a falling star.

Meteors that enter the Earth’s atmosphere are called meteoroids, while meteors that can reach the Earth’s atmosphere are called meteorites. A meteorite that falls to the earth’s surface produces a crater called meteoric crater. A meteorite once fell in Arizona, so it formed a meteoric crater of 1.3 km in diameter, its depth reached 175 m. This meteoric crater is called Barringer Creater.
