Scientists have analyzed rocks from the moon and found their makeup to be similar to the rocks in Earth’s mantle. The age of these moon rocks is very close in age to Earth’s mantle rocks. Which reasoning statement about the formation of the moon BEST supports the giant impact hypothesis?

• Because the rocks are different in makeup, they were formed from the same minerals.

• Because the rocks are similar in makeup and age, they are likely from the same source.

• Because the moon is smaller than Earth, it was likely formed from a comet.

• Because the rocks from the moon are similar to the rocks from Earth’s mantle, the moon was likely formed much later.

Scientific evidence supports the idea that as the dinosaur age was coming to an end, great changes were occurring on Earth. These changes made it possible for mammals to survive and thrive. Which of the following changes to Earth BEST suited mammals?

• dust-clouded atmosphere

• colder global temperatures

• increase in ocean water temperatures

• decrease in vegetation worldwide
