Here's why:
* Meteoroid: A small piece of rock or metal traveling through space.
* Meteor: The streak of light we see when a meteoroid enters the Earth's atmosphere and burns up.
* Meteorite: If a meteoroid survives its fiery descent and reaches the Earth's surface, it becomes a meteorite.
The flash of light is caused by the intense heat generated as the meteoroid interacts with the air molecules at high speeds. This friction causes the meteoroid to heat up and glow, producing the bright streak across the sky.
