What term describes a small solid particle traveling through space before entering Earth's atmosphere?
Asteroid
Meteoroid
Meteorite
Meteor
A meteoroid is a small rocky or metallic body traveling through space. Once it enters Earth's atmosphere and produces a streak of light, it's called a meteor. If any part reaches the ground, it's termed a meteorite. NASA: Meteoroids, Meteors, Meteorites.
What name is given to the streak of light produced when a meteoroid burns up in Earth's atmosphere?
Comet
Meteor
Meteorite
Asteroid
When a meteoroid enters the atmosphere and vaporizes, the glowing trail is called a meteor or 'shooting star.' It's not a comet or asteroid, which are larger and have different characteristics. NASA: Meteoroids, Meteors, Meteorites.
What do you call a meteoroid that survives its passage through the atmosphere and lands on Earth's surface?
Comet
Asteroid
Meteor
Meteorite
When fragments of a meteoroid reach the ground, they are known as meteorites. Meteors refer only to the flash of light in the atmosphere, and asteroids and comets are larger bodies in space. NASA: Meteoroids, Meteors, Meteorites.
Which of these objects is primarily composed of ice, dust, and rocky particles and often develops a glowing coma when near the Sun?
Meteoroid
Meteor
Asteroid
Comet
Comets are icy bodies that, when heated by the Sun, form a visible atmosphere called a coma and sometimes a tail. Asteroids are primarily rocky and metallic without a coma. Meteoroids and meteors refer to smaller rocks or the light streak they produce. NASA: Asteroids, Comets & Meteors Overview.
Which type of meteorite is the most common, making up about 85% of meteorite falls on Earth?
Iron
Chondrite
Stony-iron
Achondrite
Chondrites are the most common meteorites and contain small spherical inclusions called chondrules. They are primitive, undifferentiated material from the early solar system. Achondrites lack chondrules, and iron and stony-iron meteorites are far less abundant. University of Washington: Meteorite Types.
According to the International Astronomical Union, what is the maximum diameter for an object to be classified as a meteoroid?
1 meter
10 kilometers
100 meters
1 kilometer
The IAU defines a meteoroid as a solid object smaller than 1 meter in diameter. Larger bodies are classified as asteroids. This threshold helps distinguish small space debris from more massive near-Earth objects. IAU: Meteors Theme.
Meteor showers occur when Earth passes through debris left by which type of celestial object?
Asteroid
Moon
Planet
Comet
Meteor showers happen when Earth travels through a stream of debris, typically dust and small particles shed by a comet. This debris burns up in the atmosphere as meteors. Asteroids and planets don't produce the fine dusty trails that cause annual showers. NOAA: Meteor Showers.
What term describes a meteor that reaches a brightness greater than magnitude -4, about as bright as Venus?
Airburst
Bolide
Fireball
Shooting star
A meteor brighter than magnitude -4 is called a fireball. A bolide is a very bright fireball that explodes, while an airburst refers to the explosive fragmentation event. 'Shooting star' is a general term for any meteor. AMS: Learn About Meteors.
At approximately what altitude above Earth's surface do most meteors begin to glow?
75 kilometers
200 kilometers
5 kilometers
10 kilometers
Meteors typically begin to heat up and ionize the surrounding air at altitudes around 75 to 100 kilometers. Below this, the atmosphere becomes dense enough to produce visible light. Above that range, the air is too thin for significant ablation. NASA: Meteor Phenomena.
Which classification of meteorite lacks chondrules and is formed from volcanic activity on its parent body?
Stony-iron
Iron
Achondrite
Chondrite
Achondrites are stony meteorites that lack chondrules and originate from planets or large asteroids that underwent melting and differentiation. They are essentially extraterrestrial igneous rocks. In contrast, chondrites are primitive and contain chondrules. University of Washington: Meteorite Types.
What term is used to describe the explosive fragmentation of a meteoroid in the atmosphere, often producing a visible shock wave?
Coma
Bolide
Airburst
Fireball
An airburst occurs when a meteoroid explodes in the atmosphere due to rapid pressure buildup, producing a shock wave. A bolide is a very bright fireball that may or may not explode. A coma refers to the gas envelope around a comet nucleus, not meteoroids. Wikipedia: Airburst.
The Leonid meteor shower is produced by debris from which comet?
Tempel-Tuttle
Halley
Swift-Tuttle
Encke
The Leonids originate from the debris of Comet Tempel-Tuttle, which completes an orbit every 33 years. When Earth passes through its dust trail, particles burn up as meteors. Halley's comet produces the Orionids and Eta Aquarids, while Swift-Tuttle causes the Perseids. Wikipedia: Leonids.

Cheat Sheet
Defining Meteoroid, Meteor & Meteorite -
In the meteor vs meteorite vs meteoroid framework, a meteoroid is a small rock or particle in space, a meteor is the streak of light in our atmosphere, and a meteorite is any remnant that survives and lands on Earth. Remember the mnemonic "OID in Orbit, OR in the air, ITE on the ground" to keep them straight (NASA, 2021).
Size & Composition Differences -
Meteoroids typically range from dust grains to boulders under 1 m, while asteroids exceed 10 m - distinguishing meteor vs asteroid vs comet origins. Many meteoroids are fragments of asteroids or comets and are categorized by composition into chondrites (stony) and iron types (Smithsonian NMNH, 2020).
Atmospheric Entry & Ablation -
As a meteoroid plunges into Earth's atmosphere at speeds up to 70 km/s, it heats up and ablates, producing the visible meteor; its kinetic energy follows E=½mv², explaining the brilliant vapor trails. Such high-energy interactions create phenomena like fireballs and bolides monitored by organizations like the American Meteor Society.
Meteor Showers & Parent Bodies -
Periodic meteor showers occur when Earth crosses debris trails of comets - e.g., Perseids from Comet Swift-Tuttle and Leonids from 55P/Temple-Tuttle - highlighting the comet vs asteroid vs meteorite relationships. Recognizing shower peaks helps predict events and differentiate sporadic meteors (International Meteor Organization).
Meteorite Classification & Scientific Value -
Once recovered, meteorites are classified into chondrites, achondrites, iron, and stony-iron groups, each revealing solar system history via radiometric dating (University of Arizona's Lunar and Planetary Laboratory). Scientists study isotopic ratios to trace origins back to protoplanetary disk processes, making meteorites invaluable cosmic time capsules.
