More of the lighted surface of the Moon is facing Earth at what phase?
- A.
Waning Gibbous
- B.
Third Quarter
- C.
New Moon
- D.
Waxing Crescent
Correct Answer
A. Waning GibbousExplanation
During a waning gibbous phase, more of the lighted surface of the Moon is facing Earth. This is because the Moon is positioned between the full moon and third quarter phases, with the illuminated portion gradually decreasing. The term "waning" refers to the decreasing illumination of the Moon, while "gibbous" indicates that it is more than half illuminated but not yet full. Therefore, the waning gibbous phase has a larger illuminated area facing Earth compared to the other phases mentioned.Rate this question:

Correct Answer
B. WaxingExplanation
The phase of the moon when the amount of the Moon's lighted surface seen on Earth gets larger is called waxing. During this phase, the illuminated portion of the moon increases from a crescent shape to a half moon and eventually to a full moon. This occurs as the moon moves in its orbit around the Earth, causing different amounts of sunlight to be reflected back to Earth.Rate this question:

- D.
Seasonal Phases
Correct Answer
C. Moon PhasesExplanation
The changing appearances of the Moon as seen from Earth are referred to as Moon Phases. These phases occur due to the varying positions of the Moon, Earth, and Sun in relation to each other. As the Moon orbits the Earth, different portions of its illuminated side become visible, creating the different phases such as new moon, crescent, half moon, and full moon. This phenomenon can be observed by anyone on Earth and is a result of the Moon's rotation and the reflection of sunlight off its surface.Rate this question:

Solstice
Correct Answer
D. SolsticeExplanation
Solstice refers to the point at which the Sun reaches its greatest distance North or South of the equator. During the solstice, either the Northern Hemisphere experiences the longest day (summer solstice) or the Southern Hemisphere experiences the longest day (winter solstice). This occurs due to the tilt of the Earth's axis. It is important to note that the equinox, lunar eclipse, and solar eclipse are not related to the Sun's position in relation to the equator.Rate this question:

The moon was captured by Earth's gravity
- B.
The moon and Earth condensed from the same cloud of dust and gas
- C.
The moon spun off the molten earth due to centrifugal force
- D.
The moon was created due to the collision (impact) with the rogue planet
Correct Answer
D. The moon was created due to the collision (impact) with the rogue planetExplanation
The correct answer is that the moon was created due to the collision (impact) with the rogue planet. This theory, known as the Giant Impact Hypothesis, suggests that a Mars-sized object collided with the early Earth, causing debris to be ejected into space. This debris eventually came together to form the moon. This theory is widely accepted because it explains the similarities in composition between the moon and Earth, as well as the moon's relatively small size compared to Earth. Additionally, evidence such as the moon's lack of iron core and the similarity in isotopic compositions supports this theory.Rate this question:
