Methane gives ___________ their blue-green color.
- A.
Mars and Earth
- B.
Uranus and Neptune
- C.
Saturn and Jupiter
- D.
Neptune and Venus
Correct Answer
B. Uranus and NeptuneExplanation
Methane gives Uranus and Neptune their blue-green color. Methane is a gas that exists in the atmospheres of these two planets. When sunlight interacts with methane molecules, it absorbs red light and reflects blue and green light, resulting in the characteristic blue-green color seen on Uranus and Neptune. This is known as the Rayleigh scattering effect. Mars and Earth do not have significant amounts of methane in their atmospheres, while Saturn and Jupiter have different atmospheric compositions that do not result in a blue-green color. Venus does not have methane in its atmosphere, and its color is primarily due to a thick layer of clouds composed of sulfuric acid.Rate this question:

When Earth's shadow falls on the Moon.
- A.
Solar Eclipse
- B.
Lunar Eclipse
- C.
Equinox
- D.
Solistice
Correct Answer
B. Lunar EclipseExplanation
A lunar eclipse occurs when Earth's shadow falls on the Moon. This happens when the Earth is positioned directly between the Sun and the Moon, blocking the sunlight from reaching the Moon. As a result, the Moon appears dark or reddish in color during a lunar eclipse. This phenomenon is different from a solar eclipse, which occurs when the Moon passes between the Sun and the Earth, blocking the sunlight from reaching certain areas on Earth. Equinox and solstice are unrelated to lunar eclipses.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 a solstice, either the Northern Hemisphere experiences the longest day of the year (summer solstice) or the Southern Hemisphere experiences the shortest day of the year (winter solstice). This occurs due to the tilt of the Earth's axis. Equinox refers to the point at which the Sun is directly above the equator, resulting in equal day and night lengths. Lunar and solar eclipses, on the other hand, involve the alignment of the Sun, Earth, and Moon, causing temporary darkening of the Moon or Sun respectively.Rate this question:

The most widely accepted theory on the creation of the moon is
- A.
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 suggests that a Mars-sized object collided with the early Earth, causing debris to be ejected into space. This debris then came together to form the moon. This theory is supported by the similarities in isotopic compositions between the Earth and moon, as well as the moon's lack of iron core. Additionally, computer simulations have shown that this type of collision could have produced the moon's current orbit and characteristics.Rate this question:

Waxing
- C.
Eclipse
- D.
Full
Correct Answer
A. WaningExplanation
Waning is the correct answer because it refers to the phase of the moon when the amount of the Moon's lighted surface seen on Earth gets smaller. During this phase, the illuminated portion of the moon gradually decreases, moving from a full moon to a new moon. This is opposite to the waxing phase, where the illuminated portion of the moon increases. An eclipse refers to the alignment of the sun, moon, and Earth, causing a temporary obscuring of the moon's light.Rate this question:

- A.
Waning crescent
- B.
Waning gibbous
- C.
Waxing gibbous
- D.
First quarter
Correct Answer
C. Waxing gibbousExplanation
The current phase of the moon is waxing gibbous. This means that the moon is in the process of transitioning from a crescent shape to a full moon. During this phase, more than half of the moon is illuminated, but it is not yet completely full. The term "waxing" indicates that the illuminated portion of the moon is increasing in size. "Gibbous" refers to the moon appearing more than half but less than fully illuminated.Rate this question:
