Questions and Answers
  • 1. 

    Which is the correct order, starting with the smallest and ending with the largest?

    • A.

      Planet - star - galaxy

    • B.

      Planet - galaxy - star

    • C.

      Star - planet - galaxy

    Correct Answer
    A. Planet - star - galaxy
    Explanation
    The correct order is planet - star - galaxy because a planet is smaller than a star, and a star is smaller than a galaxy.

    What do we call an object that is in orbit around a planet?

    • A.

      A star

    • B.

      A satellite

    • C.

      A comet

    Correct Answer
    B. A satellite
    Explanation
    An object that is in orbit around a planet is called a satellite. Satellites are celestial bodies that revolve around a larger celestial body, such as a planet. They can be natural, like the Moon, or artificial, like the many communication and weather satellites that orbit Earth. Satellites play a crucial role in various fields, including communication, navigation, and scientific research.

    Which is the third planet from the sun?

    • A.

      Mars

    • B.

      Venus

    • C.

      Earth

    Correct Answer
    C. Earth
    Explanation
    The third planet from the sun is Earth.

  • 4. 

    Which force keeps the planets in orbit?

    • A.

      Fricition

    • B.

      Gravity

    • C.

      Tension

    Correct Answer
    B. Gravity
    Explanation
    Gravity is the force that keeps the planets in orbit. It is the force of attraction between two objects with mass. In the case of planets, gravity pulls them towards the center of the sun, creating a continuous circular or elliptical orbit. This gravitational force counteracts the tendency of the planets to move in a straight line and keeps them in their respective orbits. Friction and tension are not applicable forces in this context and do not play a role in keeping planets in orbit.

  • 5. 

    In which direction does the Earth spin?

    • A.

      From west to east

    • B.

      From east to west

    • C.

      From north to south

    Correct Answer
    A. From west to east
    Explanation
    The Earth spins from west to east. This is known as eastward or prograde rotation. It means that when viewed from above the North Pole, the Earth rotates counterclockwise. This rotation causes the cycle of day and night, as well as the movement of the stars and celestial bodies across the sky. The direction of the Earth's spin is also the reason why the Sun appears to rise in the east and set in the west.

    Why do we have seasons on Earth?

    • A.

      The Earth is closer to the Sun in summer than it is in winter

    • B.

      The Sun is brighter in summer than it is in winter

    • C.

      The Earth's axis is tilted

    Correct Answer
    C. The Earth's axis is tilted
    Explanation
    The Earth's axis is tilted, causing the change in seasons. This tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year. When the northern hemisphere is tilted towards the Sun, it experiences summer, while the southern hemisphere experiences winter. As the Earth orbits the Sun, the tilt causes these seasons to change.

  • 7. 

    Which phase of the Moon is this?

    • A.

      Full Moon

    • B.

      New Moon

    • C.

      Crescent Moon

    Correct Answer
    A. Full Moon
    Explanation
    The given answer is "full Moon" because a full Moon occurs when the Moon is on the opposite side of the Earth from the Sun, and the entire side of the Moon facing the Earth is illuminated. This phase appears as a complete circle and is the brightest phase of the Moon.

  • 8. 

    The further away from the Sun:

    • A.

      The faster the planet moves

    • B.

      the hotter the planet is

    • C.

      The longer the planet's orbit takes

    Correct Answer
    C. The longer the planet's orbit takes
    Explanation
    As a planet moves further away from the Sun, the gravitational pull of the Sun weakens. This results in a decrease in the planet's orbital speed, causing it to move slower. Since the planet takes longer to complete its orbit around the Sun, it spends more time away from the Sun, leading to a decrease in temperature. Therefore, the statement "the longer the planet's orbit takes" is a logical explanation for the given answer.
