Explanation:

• Earth and Moon rocks share nearly identical chemical compositions, a finding confirmed by lunar sample analysis.
• The Moon's diameter is approximately 3,474 km, while Earth's is ~12,742 km, so the Moon is about 1/4 of Earth's diameter.

Answer:

• Earth and Moon rocks are almost chemically identical
• The Moon is about one-quarter of Earth's diameter
