The correct response is:
**The composition of moon rocks and some Earth rocks are similar.**
This similarity in composition supports the giant impact theory, suggesting that the Earth and the Moon may have originated from the same material, potentially after a massive collision.

The correct response is:
**Its hydrogen atoms are heavier than others.**
Deuterium oxide (D₂O), or heavy water, contains deuterium, an isotope of hydrogen that has one neutron in addition to the usual single proton, making it heavier than regular hydrogen.

The correct response is:
**Earth's surface is constantly changing.**
The Earth's surface undergoes processes such as erosion, plate tectonics, and volcanic activity, which can destroy or alter the geologic record, making it challenging to determine the exact age of the Earth and its materials.
