* Space Debris: Our solar system is filled with bits of dust, rock, and ice leftover from its formation. These pieces are called meteoroids.

* Gravity's Pull: Earth has a strong gravitational pull, attracting everything towards it.

* Entering the Atmosphere: When a meteoroid enters Earth's atmosphere, it's pulled down by gravity.

* Friction and Heat: The meteoroid's speed and the friction caused by the air create intense heat, causing the meteor to glow and sometimes even disintegrate completely.

So, it's not that they're "falling" in the sense of dropping from a height, but rather they're being drawn down by Earth's gravitational force.
