Question

You observe high resolution images of a newly studied moon of Saturn with no significant atmosphere. you notice that the surface is overall smooth, very few craters and some rifts and ridges. What is your conclusion?

This is very old, billions of years of erosion has eliminated the impact craters

This is very young, it formed after all other moons, once most of the meteorite impacts had ended.

Some gravity-driven process must produce the rifts and ridges

You cannot say, laws of physics and chemistry are different on other planets.

Explanation / Answer

There are multiple moons of saturn is present in the universe.According to given description there are various features found on the surface of the moon i.e some regions of craterd terrain,some are smooth and some lanes of rifts & ridges.

1.Given the relative lack of the craters in the smooth plains indicates probably less than a few hundred million years old.

2.Given the relatively crater free regions filled with many rifts and ridges suggest that the surface has subjected to an extensive deformation since the formation of the craters.

The overall features indicate major resurfacing events in the geologically recent past.Thus,it is concluded that this is very young and formed after all other moons ,once most of the meteorite impact had ended.
