Why does the Moon not have lobate scarps?

The reason the Moon does not have lobate scarps is primarily related to its internal structure and thermal evolution. The Moon is geologically less active than larger bodies in the solar system. Over time, many celestial bodies with larger, molten metallic cores tend to exhibit significant geological activity, including tectonic movements that can lead to scarps.

In the case of the Moon, its interior has not contracted significantly. This is because the Moon cooled and solidified relatively quickly after its formation, resulting in a rigid crust with limited tectonic activity. Lobate scarps are formed through the contraction and buckling of a planet's crust as it cools, which is more pronounced in larger bodies with a more active geological history. Since the Moon lacks this significant contraction and geological processes, it does not display lobate scarps as seen on other celestial bodies, such as Mercury, which has a more complex geologic past and has experienced extensive cooling and contraction.
