B. 4.6 Billion
Explanation
The age of the Earth's moon is estimated to be around 4.6 billion years. This estimation is based on the analysis of moon rocks brought back by the Apollo missions, as well as the study of lunar craters and the moon's geological features. By dating the moon rocks and analyzing the impact craters, scientists have determined that the moon formed shortly after the formation of the solar system, making it approximately 4.6 billion years old.

The correct answer is 2%. The moon's gravity is about 1/6th of the Earth's gravity, which is approximately 17%. Therefore, the moon's gravity is significantly less than the Earth's gravity. The options of 9% and 23% are incorrect as they do not accurately represent the moon's gravity compared to the Earth's.

2

• B.

3

• C.

4

• D.

1

• E.

None of the Above

D. 1
Explanation
We only see one side of the moon from Earth. This is because the moon is tidally locked with Earth, meaning that it takes the same amount of time for the moon to rotate on its axis as it does to orbit around Earth. As a result, the same side of the moon always faces us, while the other side remains hidden from view.
