Neptune
-
Mercury
-
Earth
Correct Answer
A. EarthExplanation
Earth is the correct answer because it is the planet that humans inhabit. It is the third planet from the Sun and is known for its diverse ecosystems, including land, water, and atmosphere that support various forms of life. Earth is the only known planet to have a combination of liquid water, a suitable atmosphere, and a stable climate, making it uniquely habitable.Rate this question:

Where does the light of the Moon come from?
-
The Earth
-
Its own gases
-
The Sun
-
Saturn
Correct Answer
A. The SunExplanation
The light of the Moon comes from the Sun. The Moon does not produce its own light but instead reflects the sunlight that falls on its surface. This is why the Moon appears bright in the night sky. The Sun's light travels through space and reaches the Moon, illuminating it and allowing us to see it from Earth.Rate this question:

What is the Moon made out of?
-
Stars
-
Gases
-
Flowers
-
Rocks
Correct Answer
A. RocksExplanation
The Moon is made out of rocks. This is supported by scientific evidence and studies conducted on lunar samples brought back by astronauts during the Apollo missions. These samples have been analyzed and found to be composed primarily of various types of rocks, such as basalt and anorthosite. Additionally, the Moon's surface is covered in craters, which are formed by impacts from rocks and asteroids. Therefore, it is clear that the Moon is predominantly made up of rocks.Rate this question:

Which word means solar?
-
Sun
-
Earth
-
Moon
-
Star
Correct Answer
A. SunExplanation
The word "Sun" means solar because it refers to the star at the center of the solar system, which emits light and heat through nuclear fusion. It is the primary source of energy for the Earth and other planets, making it synonymous with solar energy.Rate this question:
-
- 6.
The changing shapes of the Moon are called
-
Spins
-
Phases
-
Orbits
Correct Answer
A. PhasesExplanation
The Moon doesn't emit its own light but reflects sunlight. As the Moon orbits Earth, the amount of sunlight it reflects changes, causing its appearance to change. These different appearances are called phases. The main phases of the Moon are new moon, first quarter, full moon, and last quarter.Rate this question:

Days and nights are caused by the way the Earth moves around the sun. What is this movement called?
-
Rotation
-
Phases
-
Seasons
-
Solar system
Correct Answer
A. RotationExplanation
The movement of the Earth around its own axis is called rotation. This rotation causes the cycle of day and night as different parts of the Earth are exposed to or away from the sun's light. The other options mentioned, such as phases, seasons, and solar system, are not directly related to the specific movement that causes day and night.Rate this question:

What are the objects in space made up of hot gases called?
-
Planets
-
Moons
-
Rocks
-
Stars
Correct Answer
A. StarsExplanation
Stars are objects in space made up of hot gases. They are formed when massive clouds of gas and dust collapse under their own gravity. The intense heat and pressure at the core of a star cause nuclear fusion, where hydrogen atoms combine to form helium, releasing a tremendous amount of energy in the form of light and heat. This process sustains the star's brightness and heat for millions or billions of years. Stars come in various sizes, colors, and temperatures, and they are crucial for the formation of galaxies and the existence of life on planets.Rate this question:

Which is the largest planet in the solar system?
-
Jupiter
-
Saturn
-
Mars
-
Neptune
Correct Answer
A. JupiterExplanation
Jupiter is the largest planet in the solar system. It has a diameter of about 143,000 kilometers, making it more than 11 times the size of Earth. Jupiter's immense size is due to its composition, primarily consisting of hydrogen and helium gases. Its massive size also contributes to its strong gravitational pull, which is the strongest among all the planets in the solar system.Rate this question:

The moon is not visible in the sky during the ________ phase.
-
First Quarter Moon
-
Full Moon
-
Last Quarter Moon
-
New Moon
Correct Answer
A. New MoonExplanation
During the New Moon phase, the moon is not visible in the sky. This is because the New Moon occurs when the moon is positioned between the Earth and the Sun, with the side of the moon that is illuminated facing away from us. As a result, the moon appears completely dark and cannot be seen from Earth.Rate this question:
-
- 11.
How long does it take for the phases of the Moon to start and finish?
-
1 day
-
1 week
-
1 month
-
1 year
Correct Answer
A. 1 monthExplanation
The phases of the Moon take approximately 1 month to start and finish. This is because the Moon orbits around the Earth, and as it does so, different portions of its illuminated surface become visible from Earth, creating different phases. The entire cycle of phases, from New Moon to Full Moon and back to New Moon, takes about 29.5 days to complete.Rate this question:

What is the time taken by the Earth to complete one rotation around the sun?
-
24 hours
-
24 days
-
1 month
-
1 year
Correct Answer
A. 1 yearExplanation
The time taken by the Earth to complete one rotation around the sun is 1 year. This is because the Earth revolves around the sun in an elliptical orbit, completing one full revolution in approximately 365.25 days. This duration is known as a year.Rate this question:

Name the imaginary line upon which the Earth spins.
-
Axis
-
Orbit
-
Rotation
-
Phase
Correct Answer
A. AxisExplanation
The correct answer is "axis". The axis is an imaginary line that runs through the center of the Earth from the North Pole to the South Pole. It is the line around which the Earth rotates, causing day and night. The axis is tilted, which is why we have different seasons throughout the year.Rate this question:
-

How many seasons of the year are there?
-
4
-
8
-
12

There are four seasons of the year: spring, summer, autumn, and winter. Each season is characterized by different weather patterns and temperatures. Spring is known for its blooming flowers and mild temperatures, while summer brings warm weather and longer days. Autumn is marked by falling leaves and cooler temperatures, and winter is known for its cold weather, snow, and shorter days. These four seasons occur in a cyclical pattern throughout the year.Rate this question:
