Is it ?

1. Mercury was located farther from Earth, so experienced no tidal forces.

2. dense Mercury had an iron core that shrank, creating the lobate scarps.

3. Mercury was subject to more intense asteroid bombardment than the Moon.

4. Mercury developed a strong magnetic field to protect it from solar radiation.

5. Mercury developed a dense atmosphere while the Moon never did.


I think it's # 2...but I'm not sure.
