Weekly Quiz Competition
  • Question 1
    1 / -0
    The decreasing size of the Moon from a 'Full Moon' to a 'New Moon' is called the _______.
    Solution
    'Waning Moon' means the Moon is decreasing in size, moving from the 'Full Moon' towards the 'New Moon'.
  • Question 2
    1 / -0
    Why is life not possible on the Moon?
    Solution
    The Moon has no atmosphere, so life is not possible on the Moon. Without any atmosphere, or the ability to create one, the moon cannot provide the basic conditions for life to develop.
  • Question 3
    1 / -0
    When does the lunar eclipse occur?
    Solution
    A lunar eclipse occurs when the Moon passes directly behind the Earth and into its shadow. This occurs only when the Sun, Earth, and Moon are exactly or very closely aligned, with Earth between the other two.
  • Question 4
    1 / -0
    Maximum tides occurring on a Full Moon day are known as ________.
    Solution
    A Full Moon occurs when the Earth lies between the Sun and the Moon (as the Sun sets, the Moon rises with the side that faces Earth fully exposed to sunlight). A New Moon is when the Moon lies between the Earth and the Sun (Sun and the Moon setting together) so that the gravitational attraction of both the Sun and the Moon acts on the Earth, causing higher tides, which are known as spring tides.
  • Question 5
    1 / -0
    Which of the following statements is correct regarding the Sun?
    Solution
    Sun is a star which is nearest to the Earth, but it is not the brightest star.
  • Question 6
    1 / -0
    What type(s) of nuclear reactions occur(s) in the central core of the Sun?
    Solution
    Nuclear fusion takes place in the core of the Sun, where hydrogen is converted into helium.
  • Question 7
    1 / -0
    Which among the following is called a 'dwarf planet'?
    Solution
    Pluto is called a 'dwarf planet'.
    A dwarf planet is a celestial body that orbits the Sun and has a spherical shape, but is not large enough to disturb other objects from its orbit.
  • Question 8
    1 / -0
    Which of the following planets is less dense than water?
    Solution
    Saturn is the least dense of the gas giants (composed primarily of hydrogen, helium and water, existing in various physical states). The density of Saturn is 0.687 g/cm3.
  • Question 9
    1 / -0
    Which among the following is/are not constellation(s)?

    (i) Milky Way
    (ii) Ursa Major
    (iii) Cassiopeia
    (iv) Orion
    Solution
    The Milky Way is a large barred spiral galaxy. All the stars we see in the night sky are in Milky Way galaxy. Our galaxy is called the Milky Way because it appears as a milky band of light in the sky when you see it in a really dark area.
  • Question 10
    1 / -0
    Which of the following constellations resembles letter W?
    Solution
    Cassiopeia is a constellation in the northern sky, named after the vain queen Cassiopeia in Greek mythology.

  • Question 11
    1 / -0
    Between which planets does the asteroid belt lie?
    Solution
    Asteroids are rocky, airless worlds that orbit our Sun, but are too small to be called planets. Tens of thousands of these minor planets are gathered in the main asteroid belt, a vast doughnut-shaped ring between the orbits of Mars and Jupiter. Asteroids that pass close to Earth are called Near-Earth Objects or NEOs.
  • Question 12
    1 / -0
    The tail of a comet points
    Solution
    A comet generally has two tails. One tail is due to the comet's dust particles. Dust particles form the first tail and it generally points back along the comet path.
    The other is due to ionised gas from the comet coma. The ions (electrically charged particles), which first come from the nucleus as (neutral) gaseous particles, are swept into the second comet tail. Because of the interaction with the Sun's magnetic field, this tail always points directly away from the Sun.

  • Question 13
    1 / -0
    A comet has ______.
    Solution
    There are two types of comet tails: Dust tail and Gas (Ion) tail. A dust tail contains small, solid particles that are about the same size found in cigarette smoke. This tail forms because sunlight pushes on these small particles, gently shoving them away from the comet's nucleus. A gas (ion) tail is formed due to ionised gas from the comet coma. The ions (electrically charged particles), which first come from the nucleus as (neutral) gaseous particles, are swept into the second comet tail.

  • Question 14
    1 / -0
    What is the use of a remote sensing satellite?
    Solution
    A remote sensing satellite can be used for spotting underground oil.

  • Question 15
    1 / -0
    A meteor shower can be seen only when
    Solution
    A meteor shower is the result of an interaction between a planet, such as Earth, and tail of a comet.


  • Question 16
    1 / -0
    The term 'meteoroid' is applied to an interplanetary body. Which of the following is correct about a meteor?
    Solution
    Meteoroid is a small particle from a comet or an asteroid orbiting the Sun. The light phenomenon which results when a meteoroid enters the Earth's atmosphere and vaporises is known as meteor.
  • Question 17
    1 / -0
    Which of the following planets takes 11 years to complete one revolution around the Sun?
    Solution
    It takes Jupiter approximately years to complete a revolution around the Sun. Jupiter's average orbit distance from the Sun is 778 million kilometres, which is about a little more than 5 times the average distance between Earth and the Sun, 150 million kilometres.
  • Question 18
    1 / -0
    Which phase of the Moon is shown in the following figure?

    Solution
    The Waxing Crescent Moon starts as the Moon becomes visible again after the New Moon conjunction, when the Sun and Earth were on opposite sides of the Moon, making it impossible to see the Moon from the Earth.
    Waxing means that it is growing, while crescent refers to the curved shape similar to a banana or a boat.
  • Question 19
    1 / -0
    The First Quarter Moon is often called Half Moon because we can see exactly 50% of the Moon's surface illuminated.

    What is the period called when we are seeing less and less of the Moon each night?
    Solution
    The moon wanes when it gradually appears less and less round, after the Full Moon.
  • Question 20
    1 / -0
    Which of the following is incorrect for the planet Mercury?
    Solution
    Mercury is the smallest and innermost planet in the solar system.
    Its orbital period (about 88 Earth days) is less than that of any other planet in the solar system.
    It has no known natural satellites.
    Although Mercury can appear as a bright star-like object when viewed from Earth, its nearness to the Sun often makes it more difficult to see than Venus.
    The statement given in option (4) is incorrect because Venus is the planet called as 'Morning star'.
