Question

From the small number of impact craters on ____, planetary geologists suspect that virtually all its original surface has been covered over by younger volcanic activity

Answer 1

Planetary geologists suspect that the original surface of a certain celestial body has been covered by younger volcanic activity, based on the small number of impact craters. Evidence of past impact events is gradually erased by the constant renewal of Earth's crust through plate tectonics.

Step-by-step explanation:

Based on the small number of impact craters, planetary geologists suspect that virtually all the original surface of a certain celestial body has been covered by younger volcanic activity.

This can be observed in the case of Earth, where the constant renewal of its crust through plate tectonics gradually erases evidence of past impact events.

Geologists have identified eroded remnants of impact craters on Earth, providing evidence for the influence of these impacts on the planet's evolution over time.

Answer 2

From the small number of impact craters on moon, planetary geologists suspect that virtually all its original surface has been covered over by younger volcanic activity. Most of the Moon's surface is densely covered with craters, but we find relatively few craters within the lunar maria.
