Question 1

The origin of the Moon is thought to be best explained by _____.&#10;A) fission&#10;B) condensation&#10;C) capture&#10;D) collision

Accepted Answer

The collision theory, also known as the giant impact hypothesis, is the most widely accepted explanation for the origin of the Moon. It suggests that the Moon formed from the debris left over after a Mars-sized body collided with Earth early in the solar system's history.

Question 2

Craters on the Moon are created mostly by _____.&#10;A) impact&#10;B) volcanoes&#10;C) plate tectonics&#10;D) rifting

Accepted Answer

Craters on the Moon are primarily formed by the impact of meteoroids and comets, not by volcanic activity, plate tectonics, or rifting, as the Moon lacks significant geological activity in these areas.

Question 3

The Marias on the Moon are primarily this type of rock: ______.&#10;A) anthracites&#10;B) granite&#10;C) basalt&#10;D) sediments

Accepted Answer

The Marias on the Moon are primarily made of basalt, which is a type of volcanic rock. These dark, flat plains were formed from ancient volcanic eruptions.

Question 4

Mountains on the Moon were formed by&#10;A) volcanic eruptions.&#10;B) plate tectonics.&#10;C) impacts from space.&#10;D) folding as the Moon cooled and shrank.

Accepted Answer

Mountains on the Moon were primarily formed by impacts from space, where large asteroids and comets collided with the Moon, creating craters and pushing up surrounding material to form mountain ranges.

Question 5

The average density of the Moon is _____.

Accepted Answer

The answer of The average density of the Moon is...

Question 6

The Moon has ___________ rotation.

Accepted Answer

The answer of The Moon has ___________ rotation....

Question 7

The Marias are newer areas on the Moon.

Accepted Answer

The Maria are relatively younger areas on the Moon, formed by ancient volcanic eruptions.

Question 8

The far side of the Moon is primarily covered by craters.

Accepted Answer

The far side of the Moon is heavily cratered and lacks the large, dark, basaltic plains, or maria, that are so prominent on the Moon's near side. This difference is due to the thicker crust on the far side, which has prevented magma from reaching the surface and forming maria.
