How long is a lunar month?
-
365,24 days
-
29,5 days
-
45 days
-
28 days
Correct Answer
A. 28 daysExplanation
A lunar month is the time it takes for the moon to complete one full cycle of its phases, from new moon to new moon. This cycle typically lasts for approximately 29.5 days, which is why the correct answer is 29.5 days. It is important to note that a lunar month is different from a calendar month, which is typically 28, 30, or 31 days long.Rate this question:

-
Mars, Venus, Mercury, Earth, Jupiter, Neptune, Uranus.
Correct Answer
A. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.Explanation
The correct answer lists the planets in the correct order starting from the closest to the sun (Mercury) and ending with the farthest (Neptune). The order follows the pattern of the planets in our solar system based on their distance from the sun.Rate this question:

How long does it take the Earth to turn once on its axis?
-
24 hours
-
365.5 days
-
30 days
-
12 hours
Correct Answer
A. 24 hoursExplanation
The Earth takes 24 hours to complete one full rotation on its axis. This is known as a day. The rotation of the Earth on its axis is what causes day and night. As the Earth rotates, different parts of it are exposed to the Sun's light, creating the cycle of day and night that we experience. Therefore, the correct answer is 24 hours.Rate this question:

The Sun is a?
-
Dying star
-
Star
-
Planet
-
Constellation
Correct Answer
A. StarExplanation
The Sun is a star. It is a massive ball of hot, glowing gases that produces light and heat through nuclear fusion. It is the closest star to Earth and is essential for sustaining life on our planet. The Sun's energy is generated by the fusion of hydrogen atoms into helium in its core, releasing a tremendous amount of energy in the process. It is not a planet or a constellation, and while it will eventually exhaust its nuclear fuel and evolve, it is not currently classified as a dying star.Rate this question:

The difference between a meteoroid and an asteroid is....?
-
A meteoroid is much smaller than an asteroid.
-
A meteoroid is a block of ice while an asteroid is a rock.
-
A meteoroid orbits the sun and an asteroid crashes into earth.
-
All of the above.
Correct Answer
A. A meteoroid is much smaller than an asteroid.Explanation
The correct answer is that a meteoroid is much smaller than an asteroid. This is because meteoroids are generally small rocky or metallic objects that are smaller than asteroids. Asteroids, on the other hand, are larger rocky or metallic objects that can range in size from a few meters to hundreds of kilometers in diameter. Therefore, the main difference between a meteoroid and an asteroid is their size.Rate this question:

Which is nearer to Earth?
-
The moon.
-
The Sun.
-
Mars.
-
The evening star.
Correct Answer
A. The moon.Explanation
The moon is the correct answer because it is the closest celestial body to Earth. While the Sun is much larger and brighter, it is also much farther away. Mars is a planet that is also farther from Earth than the moon. The evening star is a term used to refer to the planet Venus, which is closer to Earth than Mars but still farther than the moon. Therefore, out of the given options, the moon is the nearest to Earth.Rate this question:

A year is...?
-
269 days
-
302,25 days
-
24 days
-
365,25 days
Correct Answer
A. 365,25 daysExplanation
A year is typically defined as the time it takes for the Earth to complete one orbit around the Sun. This period is approximately 365.25 days. The extra 0.25 days account for the slight discrepancy between the Earth's orbit and the standard 365-day calendar year. To compensate for this difference, a leap year is added every four years, where an extra day (February 29th) is included. This ensures that the calendar remains aligned with the Earth's orbit over time.Rate this question:

It seams that the Sun is moving around the Earth but in-fact it is....
-
Moving from east to west.
-
Moving from west to east.
-
The Earth that is moving not the Sun.
-
The Earth and the Sun that move together.
Correct Answer
A. The Earth that is moving not the Sun.Explanation
The correct answer is that the Earth is moving, not the Sun. This is because the apparent motion of the Sun across the sky from east to west is actually caused by the rotation of the Earth on its axis. The Earth rotates from west to east, giving the illusion that the Sun is moving around the Earth. However, in reality, it is the Earth's rotation that is responsible for this apparent motion.Rate this question:

Day and night is caused because....
-
The same part of the Earth always faces the Sun.
-
The part of the Earth that faces the Sun is lit up and the opposite side is dark.
-
The moon only shines on half of the Earth so the other side is in the dark.
-
The shadow of the sun covers half of the Earth.
Correct Answer
A. The part of the Earth that faces the Sun is lit up and the opposite side is dark.Explanation
Day and night is caused because the part of the Earth that faces the Sun is lit up and the opposite side is dark. This is due to the rotation of the Earth on its axis. As the Earth rotates, different parts of it are exposed to the Sun's light, creating day in those regions. At the same time, the parts of the Earth that are on the opposite side of the rotation are facing away from the Sun, resulting in darkness and night in those areas. This cycle of rotation creates the phenomenon of day and night on Earth.Rate this question:
