Meteoroids
A meteoroid is a small rocky or metallic body in outer space. It is significantly smaller than an asteroid and ranges in size from small grains to about 1 meter in diameter. Meteoroids are the precursors to meteors, which are commonly known as shooting stars when they enter Earth's atmosphere.
Characteristics of Meteoroids
- Size: Meteoroids can vary in size, from tiny particles to objects up to 1 meter in diameter.
- Composition: They are composed of rock, metal, or a mixture of both.
- Origin: Most meteoroids originate from comets or asteroids.
- Speed: They travel at high speeds through space.
Study Guide
- What is a meteoroid and how does it differ from an asteroid?
- Describe the composition of meteoroids.
- Explain the origin of most meteoroids.
- Discuss the speed at which meteoroids travel through space.
Be sure to understand the differences between meteoroids, meteors, and meteorites, as well as their respective characteristics and processes.

Earth History: Explain how sedimentary rock is formed periodically, embedding plant and animal remains and leaving a record of the sequence in which the plants and animals appeared and disappeared.
Explain how sedimentary rock buried deep enough may be reformed by pressure and heat and these reformed rock layers may be forced up again to become land surface and even mountains.
