2:28 PM people.ucsc.edu iPad e 100%- Frequ ency ,saturation size Figure 1. Hypothetical crater size-frequency distributions. 2) Figure 1 shows hypothetical crater size-frequency distributions (A and B) for two different planetary surfaces. a) Which surface is older and why? [1] b) Give two possible explanations for the deficit in small craters seen for population A c) Why might A be saturated for small to intermediate sized craters but not for large craters? [1] d) Large craters on B were probably produced by the same population of impactors which produced large craters on A. How do we know this? Do you think the small craters on B were produced by the same population? [2] e) Suggest one scenario in which a surface might experience two different populations of impactors 12] [8 total]

Explanation / Answer

a. Surface A is older as it posses saturation surface on it and it has lacked in small craters.

b. A possible explanation for the deficit in small craters seen for population A includes:
1. Surface A being older lacks small craters.
2. Surface B might have been more susceptible to the more geological events or meritocratic impact.

c. A is older in age compared to that of B it is saturated for the small or medium size craters.

d. Large craters on A and B were produced by the same impactors this can be inferred by the same size of the large craters on the both the surface, whereas the small which is found on the surface B is not formed by the same impactor they might have developed by the different impactor causing a variation in the size in the craters.

e. The variation in the size of the craters is the most suitable condition that implies that the surface A and B have been developed by the two different impactors.
