Question

Describe some ways in which a meteorite can be distinguished from a terrestrial rock.

a) Meteorites have a higher water content.
b) Meteorites often have a fusion crust.
c) Meteorites are always composed of iron.
d) Meteorites are more colorful than terrestrial rocks.

Answer 1

Ways to distinguish a meteorite from a terrestrial rock include the presence of a fusion crust, higher metal content, and the presence of organic compounds or amino acids.

Step-by-step explanation:

When distinguishing between a meteorite and a terrestrial rock, there are several ways to tell them apart. First, meteorites often have a fusion crust, which is a thin layer that forms on the surface as the meteorite heats up during entry into Earth's atmosphere. This fusion crust can have a characteristic black, brown, or reddish color. Second, meteorites can have a higher metal content compared to terrestrial rocks. Lastly, some meteorites, such as carbonaceous meteorites, can contain organic compounds or amino acids that are not typically found in terrestrial rocks.
