    How do stars near the North Pole appear to move?

    • In circles around Polaris

    • In orbit around the Sun

    • In orbit around the Moon

    Correct Answer
    A. In circles around Polaris
    Explanation
    Stars near the North Pole appear to move in circles around Polaris. This is because Polaris, also known as the North Star, is located very close to the celestial north pole. As the Earth rotates on its axis, the stars seem to revolve around Polaris in a circular motion. This phenomenon is due to the Earth's rotation and the position of Polaris, which remains relatively fixed in the northern sky.

    What causes a constellation to rise and set in the sky?

    • Earth's rotation

    • The rotation of Polaris

    • The orbit of Earth around the constellation

    Correct Answer
    A. Earth's rotation
    Explanation
    The correct answer is Earth's rotation. As the Earth rotates on its axis, different constellations become visible in the sky at different times. This rotation causes the stars to appear to rise in the east and set in the west. The rotation of Polaris, also known as the North Star, is not responsible for the rising and setting of constellations. Additionally, the orbit of Earth around the constellation does not affect their rising and setting.

    An impact crater forms when

    • Water, wind, and gravity change the surface of an object in space

    • An object traveling in space collides with a larger object in space

    • Periods of atmospheric cooling take place on an object in space

    Correct Answer
    A. An object traveling in space collides with a larger object in space
    Explanation
    An impact crater forms when an object traveling in space collides with a larger object in space. This collision causes a tremendous release of energy, resulting in the excavation and deformation of the surface, creating a crater. The force of the impact causes the displaced material to be ejected outward, forming a raised rim around the crater and sometimes creating secondary craters. The size and shape of the crater depend on the size, speed, and angle of the impacting object, as well as the composition and structure of the target object.

    A galaxy is a group of stars

    • Kept apart by the planets between them

    • Held together by their own gravity

    • That form a pattern in the sky

    Correct Answer
    A. Held together by their own gravity
    Explanation
    A galaxy is a vast collection of stars that are held together by their own gravity. The gravitational force between the stars keeps them from drifting apart, creating a cohesive structure. This gravitational attraction allows the stars to orbit around a common center of mass, forming a distinct pattern in the sky. The planets between the stars do not play a role in holding the galaxy together, as their gravitational influence is much smaller compared to the stars.
