Question

review the fifth and sixth paragraphs. meteorites may resemble earth rocks, but they usually have a burned exterior. this fusion crust is formed as the meteorite is melted by friction when it passes through the atmosphere. there are three major types of meteorites: the irons, the stones, and the stony - irons. although the majority of meteorites that fall to earth are stony, more of the meteorites that are discovered long after they fall are irons; these heavy objects are easier to distinguish from earth rocks than stony meteorites are. more than fifty thousand meteorites have been found on earth. of these, a tiny 0.2 percent come from mars or the moon. the remaining 99.8 percent come from asteroids. contrary to popular belief, asteroids and the meteorites that fall to earth are not pieces of a planet that broke apart, but how do the fifth and sixth paragraphs work together? they describe the composition of meteorites and how scientists determine their composition. they both describe different parts of a meteor and what characterizes each part. they describe the composition of meteorites and why their composition is significant. they both describe different types of meteorites and how to distinguish them.

Explanation:

Paragraph 5 describes the three major types of meteorites (irons, stones, stony - irons) and their characteristics (e.g., irons are easier to distinguish). Paragraph 6 gives the composition sources (asteroids, Mars/moon) of meteorites. Together, they describe the composition of meteorites (types and sources) and why composition is significant (e.g., irons are more easily discovered, source information).

Answer:

They describe the composition of meteorites and why their composition is significant.
