Final answer:
It is true that Earth's active geological processes, such as volcanic eruptions and erosion, continue to rework its surface, erasing evidence of old impact craters and keeping Earth's surface relatively young and less cratered compared to other celestial bodies.
Step-by-step explanation:
The statement that Earth is not as cratered as the other terrestrial planets due to its active geological processes is true. Earth's dynamic geological activity, such as volcanic eruptions, erosion, and the movement of tectonic plates, reworks the surface of our planet continuously. This keeps Earth's surface relatively young, with most of Earth's surface material being less than 200 million years old.
In contrast, our own Moon and other celestial bodies, like Mercury or Mars, have surfaces that have been pockmarked by impacts and remain relatively unchanged over billions of years due to the lack of geological activity. The continuous reshaping of Earth's surface has thus eradicated most evidence of old impact craters, unlike inactive celestial bodies that still carry these scars from their pasts.
In summary, the geological processes of Earth effectively erase the record of impact craters over time, making Earth appear less cratered when compared to many other terrestrial planets and moons of our solar system.
