The stark, heavily-cratered surface of the Moon is a geological time capsule, preserving a record of the earliest, most violent eras of solar system history. The visual evidence presented in this image directly ties into two fundamental concepts in planetary science: the process of accretion, as described by the Nebular Hypothesis, and the catastrophic events of the Late Heavy Bombardment (LHB). How does this image of lunar craters serve as physical evidence for both the systematic birth of the solar system and a hypothesized period of intense cosmic violence?
a)
The deep, circular craters formed by explosions are a result of the Moon's volcanic history, which occurred immediately after the solar nebula condensed into a disk.
b)
The craters are evidence of impact events that would be expected during both the final stages of accretion (Nebular Hypothesis) and the subsequent cataclysmic era known as the Late Heavy Bombardment (LHB).
c)
The uniform distribution of craters proves that the impact rate has been constant throughout solar system history, which contradicts the main predictions of the Nebular Hypothesis.
d)
Craters are only found on the Moon's near side, which shows that the impactors during the LHB were gravitationally captured by the Earth and funneled toward one side of the Moon.
13.
The image shows two prominent impact craters on the Moon's surface. Crater A is a large, well-defined crater with a central peak. Crater B is a smaller, sharper crater located on the upper right rim of crater A, with bright ejecta rays extending outwards.
What can we say about the relative age of impact B vs impact A?
a)
Impact A is younger because it is much larger, and the largest impacts occurred later in the Moon's history.
b)
Impact B is older because it is smaller, and the rate of impacts has been steadily decreasing since the Moon formed
c)
Impact B is younger than Impact A because it crosscuts the rim of Crater A.
d)
Impacts A and B are the same age because they both occur on the lunar surface, meaning they were formed during the same catastrophic event.
14.
A mass extinction event wiped out the non-avian dinosaurs. Scientists have identified a thin layer of sediment enriched in iridium, a metal rare in Earth's crust but common in asteroids, worldwide at the K–T boundary. Fossil evidence shows a sudden disappearance of dinosaur species after this layer. Geologists use this layer as a marker horizon to correlate sedimentary rocks in different locations.
Based on the information above and the image below, in what rock layers would we expect to see dinosaur fossils?
a)
We would expect to see dinosaur fossils only exactly on the K-T boundary because that is where every dinosaur died
b)
We would expect to see dinosaur fossils below and up to the K-T boundary because older rocks are found at the bottom
c)
We would expect to see dinosaur fossils above the K-T boundary because older rocks are found on top
d)
We would expect to see dinosaur fossils below the K-T boundary because they sunk to the bottom over time
