Question

What evidence suggests that Venus has been resurfaced within the last half billion years?

a.Images of Venus's surface suggest that crystallization of molecules in Venus's high-pressure atmosphere has steadily changed the surface over the last half billion years.

b.The cratering record suggests that the old, cratered highlands on Venus's surface were created by large asteroids striking Venus within the last half billion years.  

c. Images of Venus's surface suggest that erosion by water and a fast-moving lower atmosphere has steadily changed the surface within the last half billion years.

d. Since the cratering rate between Venus, Earth, and the moon are about the same, and since Venus has fewer craters than the moon, Venus must have eroded or covered many of its older craters. The cratering record suggests this happened in the last half billion years.

Explanation / Answer

Option d is the right answer. As we know that space has many celestical bodies which are orbiting around many planet in random manner . While doing so they also come in to encounter with venus and as venus doesn't have atmosphere so they are not able to stop these meteroites which impact the venus surface and form crater which is responsible for erosion of the surface many a times.
