Tutoring science, meteors and their kin might arise. The tutor defines meteor, meteoroid, and meteorite.
A meteor is the streak of light you might see in the sky at night, when matter travelling through space enters Earth’s atmosphere.
The rock, or whatever matter arrives, is typically travelling at high speed. The air friction it encounters in the atmosphere heats it up, usually to evaporation – but not always. However, it gets so hot it glows, which is what you observe.
The object itself, arriving in Earth’s atmosphere and glowing, is a meteoroid.
Any part of the meteoroid that lands on Earth’s surface becomes a meteorite. As I understand, meteoroids rarely manage to become meteorites.
