(m)

A meteor is the visible path of a meteoroid that enters the Earth's (or another body's) atmosphere, commonly called a shooting star or falling star.

For bodies with a size scale larger than the atmospheric mean free path (10 cm to several meters) the visibility is due to the heat produced by the ram pressure (not friction, as is commonly assumed) of atmospheric entry. Since the majority of meteors are from small sand-grain size meteoroid bodies, most visible signatures are caused by desiccation following the individual collisions between vaporized meteor atoms and atmospheric constituents.

A very bright meteor may be called a fireball or bolide. The International Meteor Organisation defines fireballs as being meteors of magnitude -3 or brighter. The meteor section of the British Astronomical Association on the other hand has a much stricter definition, requiring the meteor to be magnitude -5 or brighter.

If a meteoroid survives its transit of the atmosphere to come to rest on the surface, the resulting object is called a meteorite. A meteor striking the Earth or other object may produce an impact crater.

Molten terrestrial material "splashed" from such a crater can cool and solidify into an object known as a tektite.

Meteor dust particles left by falling meteoroids can persist in the atmosphere for up to several months. These particles might affect climate, both by scattering electromagnetic radiation and by catalyzing chemical reactions in the upper atmosphere.

NOT meteorology - that's the weather.

I will assume that it will fall under the space/planetary science - astronomy.

well i'm pretty sure it's not meteorology, that's studying the weather.
