Questions: 8. Why would the composition of a meteorite resemble the Earth's interior? a. They were both formed from the same nebula, out of the same atoms. b. All meteorites were once part of Earth that exploded into space. c. All materials from space are made of oxygen. d. Traveling through the atmosphere alters the meteorite so that it looks like Earth.

The answer is the first one (or A): they were both formed from the same nebula, out of the same atoms.

Explanation for each option:

a. They were both formed from the same nebula, out of the same atoms.

• Correct. Both the Earth and meteorites originated from the same primordial solar nebula, which means they share a common source of materials. This explains why their compositions can be similar.

b. All meteorites were once part of Earth that exploded into space.

• Incorrect. While some meteorites are fragments of larger bodies that may have collided with Earth, not all meteorites originated from Earth. Most meteorites are remnants of the early solar system and have never been part of Earth.

c. All materials from space are made of oxygen.

• Incorrect. While oxygen is a common element in the universe, not all materials from space are made of oxygen. Meteorites contain a variety of elements, including iron, nickel, silicon, and others.

d. Traveling through the atmosphere alters the meteorite so that it looks like Earth.

• Incorrect. While traveling through the atmosphere can cause some changes to the surface of a meteorite (such as melting or ablation), it does not fundamentally alter its overall composition to resemble Earth's interior.

Summary: The composition of a meteorite resembles the Earth's interior because they were both formed from the same nebula, out of the same atoms. This common origin explains the similarities in their compositions.
