Given That All Bodies in the Solar System Should Have

question 96

Multiple Choice

Given that all bodies in the solar system should have suffered equally from collisions during the period of early bombardment, if we find a body with relatively few craters on its surface we deduce that

• A) the surface of the body is made of material that produces fewer impact craters
• B) the body must have been located in a region of the solar system that for some reason suffered fewer collisions
• C) the body must have formed after the period of early bombardment
• D) geological activity or other processes must have removed older craters resulting in a younger, smoother surface
