Mercury's evolution was different from the Moon's because:
A)Mercury developed a dense atmosphere while the Moon never did.
B)Mercury was located farther from Earth, so experienced no tidal forces.
C)Mercury was subject to more intense asteroid bombardment than the Moon.
D)dense Mercury had an iron core that shrank, creating the tall scarps.
E)Mercury developed a strong magnetic field to protect it from solar radiation.

Question

Quizplus · Accepted Answer

Mercury's evolution was different from the Moon's because dense Mercury had an iron core that shrank, creating the tall scarps. This resulted in the planet's surface to shrink and buckle, creating tall cliffs and scarps. The Moon, on the other hand, has a small, inactive core and did not experience significant surface shrinkage or tectonic activity. Mercury's evolution led to the development of a dense core made mostly of iron. As the core cooled and shrank, the planet's crust was also compressed, creating the tall scarps seen on the planet's surface. This process was different from the Moon's evolution as the Moon's core did not have the same composition, and thus did not cause the same type of surface features.
