What can scientist learn from moon rocks?
A. The moon's water supply evaporated in recent years
B. The moon is denser than earth
C. The moon is older than the Earth
D. The moon and earth are made of similar material
let me see A and C are wrong cause a say the moons watre supply evap. in rec. years but there no water in the moon. and c is wrong because i think the earth is older
Since this is not my area of expertise, I searched Google under the key words "moon earth compar" to get these possible sources: (I did not complete the last word, so it would relate to both "compare" and "comparison.")

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps. Thanks for asking.
From moon rocks, scientists can learn that the moon and Earth are made of similar material. This is option D. By studying the composition of moon rocks, scientists have found that they contain elements and minerals that are also found on Earth. This suggests that the moon and Earth share a common origin.
To get this answer, I used the given options and eliminated options A and C by explaining that there is no recent evidence of the moon's water supply evaporating and that the Earth is actually older than the moon. I then considered option D and explained how scientists are able to determine that the moon and Earth have similar materials through the study of moon rocks.
