Question

12 multiple choice 2 points which of the following statements describes a result of earths gravitational pull on the moon? the moon has craters. the moon orbits around earth. the moon lacks an atmosphere. the moon has less gravity than earth. 13 multiple choice 2 points why does the moon only have \\( \frac { 1 } { 6 } \\) of the earths gravity? it is very far away from earth. it has less mass than earth. it is made of basalt. it has no atmosphere.

Explanation:

• For question 12:
• The Moon having craters is due to impacts from asteroids, comets, etc., not Earth's gravitational pull.
• The Moon lacking an atmosphere is related to its weak gravity (not Earth's pull) and other factors like its small size and lack of a strong magnetic field.
• The Moon having less gravity than Earth is an inherent property related to its mass, not a direct result of Earth's gravitational pull on it.
• However, Earth's gravitational pull on the Moon causes the Moon to orbit around Earth (as per Newton's law of gravitation which states that a gravitational force between two objects causes one to orbit the other if the conditions are right).
• For question 13:
• The distance from Earth does not determine the Moon's own gravity (which is an intrinsic property of the Moon).
• The composition (being made of basalt) does not directly affect the Moon's gravity.
• The lack of an atmosphere is a consequence of the Moon's weak gravity (not the cause of it).
• According to the formula for gravitational acceleration \(g=\frac{GM}{R^{2}}\) (where \(G\) is the gravitational constant, \(M\) is the mass of the object, and \(R\) is the radius of the object), since the Moon has less mass (\(M\)) than Earth (and relatively similar radius - size comparison), it has weaker gravity.

Answer:

1. The Moon orbits around Earth.
2. It has less mass than Earth.
