    When large portion of illuminated side of the moon is facing towards the Earth, we can see a large potion of the Moon from the Earth.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    When a large portion of the illuminated side of the moon is facing towards the Earth, it means that the moon is in a phase called "full moon." During a full moon, the entire face of the moon that is visible from Earth is lit up by the sun, making it appear as a complete circle. Therefore, it is true that when a large portion of the illuminated side of the moon is facing towards the Earth, we can see a large portion of the moon from the Earth.

    What are two types of eclipses________

    Correct Answer
    Solar and Lunar, Solar Lunar, Lunar and Solar, Solar Eclipse and Lunar Eclipse
    Explanation
    The correct answer is Solar and Lunar. This is because there are two main types of eclipses: solar eclipses and lunar eclipses. A solar eclipse occurs when the Moon passes between the Sun and the Earth, blocking the sunlight and casting a shadow on the Earth. On the other hand, a lunar eclipse occurs when the Earth passes between the Sun and the Moon, causing the Earth's shadow to fall on the Moon. Therefore, the answer options Solar and Lunar, Solar Lunar, Lunar and Solar, and Solar Eclipse and Lunar Eclipse all refer to the two types of eclipses.

    The side of the Moon facing Earth receives no sunlight and hence, cannot be seen from the Earth. This phase is called _________________ 

    • Gibbous Moon

    • New Moon

    • Crescent Moon

    • Half Moon

    Correct Answer
    A. New Moon
    Explanation
    During a New Moon phase, the side of the Moon facing Earth is not illuminated by sunlight, making it appear dark. This is because the Moon is positioned between the Earth and the Sun, causing the Sun's light to be blocked from reaching the side of the Moon facing us. As a result, the New Moon phase is characterized by the Moon being invisible or not visible from Earth.

    The moon revolves around the Earth every________ days?

    • 23.7

    • 27.3

    • 32.7

    • 27.5

    Correct Answer
    A. 27.3
    Explanation
    The correct answer is 27.3. The moon takes approximately 27.3 days to complete one revolution around the Earth. This period is known as the sidereal month. It is slightly shorter than the length of a calendar month because during this time, the Earth has also moved in its orbit around the Sun. The moon's revolution around the Earth is responsible for the phases of the moon that we observe from Earth.

    The time period between two full moon is about ____________

    • Two Month

    • 29.5days

    • 20days

    • 40days

    Correct Answer
    A. Two Month
    Explanation
    The time period between two full moons is approximately two months. This is because the lunar cycle, which is the time it takes for the moon to go through all of its phases, including full moon, is about 29.5 days. Since there are 12 months in a year, it follows that the time period between two full moons is approximately two months.
