    • Goldilock's zone

    • Kepler's zone

    • Blue zone

    • Drake's zone

    Correct Answer
    A. Goldilock's zone
    Explanation
    The correct answer is Goldilock's zone. This term refers to the habitable zone around a star, where conditions are just right for liquid water to exist on a planet's surface. It is neither too hot nor too cold, making it a potential place for life as we know it to thrive. The name "Goldilock's zone" is derived from the fairy tale of Goldilocks and the Three Bears, where Goldilocks searches for the perfect porridge temperature that is neither too hot nor too cold.

    Why does europa have a molten core?

    • Due to sunlight

    • Due to constant bombardment of asteroids

    • Due to tidal forces heating the core

    • Due to high spin of the moon

    Correct Answer
    A. Due to tidal forces heating the core
    Explanation
    Europa has a molten core due to tidal forces heating the core. Tidal forces are caused by the gravitational pull of Jupiter and other nearby moons, which create a stretching and squeezing effect on Europa's interior. This constant flexing generates heat, leading to the melting of the core. This phenomenon is similar to how tidal forces from the Moon affect Earth's tides. The heat generated by tidal forces on Europa's core is believed to contribute to the moon's subsurface ocean and potentially create conditions suitable for life.

    What will happen at the end of sun's life?

    • It'll form a black hole

    • It'll form a white dwarf

    • It'll form a neutron star

    • It has no end

    Correct Answer
    A. It'll form a white dwarf
    Explanation
    At the end of the sun's life, it will form a white dwarf. This is because the sun is not massive enough to undergo a supernova explosion and collapse into a neutron star or form a black hole. Instead, it will shed its outer layers and leave behind a dense core composed mainly of carbon and oxygen. This core will continue to radiate heat and slowly cool down over billions of years, eventually becoming a white dwarf.

    What is the role of Jupiter in aiding life on earth?

    • Absorbs radiation

    • Prevents us from flying off

    • Protects us from comets and asteroids

    • None

    Correct Answer
    A. Protects us from comets and asteroids
    Explanation
    Jupiter plays a crucial role in protecting Earth from comets and asteroids. Its massive gravitational pull acts as a gravitational shield, attracting and capturing many potentially dangerous space objects that could otherwise collide with our planet. This helps to reduce the frequency of catastrophic impacts, safeguarding life on Earth. Additionally, Jupiter's presence in our solar system also influences the orbits of other celestial bodies, further decreasing the likelihood of dangerous encounters with comets and asteroids.

    What is the name of the argument which suggests that universe is 'fine-tuned'to our existence?

    • Anthropic principle

    • Harvey's paradox

    • Olber's paradox

    • Hawking principle

    Correct Answer
    A. Anthropic principle
    Explanation
    The anthropic principle is the name of the argument that suggests the universe is 'fine-tuned' to our existence. This principle states that the conditions and fundamental constants of the universe are precisely set in a way that allows for the development of intelligent life. It suggests that if the universe were not finely tuned, we would not exist to observe it. This principle is often used in discussions about the nature of the universe and the existence of life.

    What experiment produced organic molecules from non biological molecules?

    • Urey-miller

    • Uri-corner

    • Upsy-daisy

    • Uri-gellar

    Correct Answer
    A. Urey-miller
    Explanation
    The Urey-Miller experiment produced organic molecules from non-biological molecules. This experiment simulated the conditions of early Earth's atmosphere and used electrical sparks to mimic lightning. These sparks caused chemical reactions among the gases present, such as methane, ammonia, and water vapor. The experiment resulted in the formation of various organic compounds, including amino acids, which are the building blocks of proteins. This experiment provided evidence that organic molecules, essential for life, could have originated from non-living materials on early Earth.

    Why is magnetic field necessary for life?

    • Deflects iron based meteorites

    • Helps in plant growth

    • Enables tectonic activity

    • Protects against radiation

    Correct Answer
    A. Protects against radiation
    Explanation
    The magnetic field is necessary for life because it protects against radiation. Earth's magnetic field acts as a shield, deflecting harmful solar radiation and cosmic rays from reaching the surface. Without this protective barrier, life on Earth would be exposed to high levels of radiation, which can be detrimental to living organisms. Therefore, the magnetic field plays a crucial role in maintaining a habitable environment for life to thrive.

    Which planet has almost 100 degree tilt?

    • Venus

    • Uranus

    • Saturn

    • Neptune

    Correct Answer
    A. Uranus
    Explanation
    Uranus has an almost 100 degree tilt, which means that its axis of rotation is almost parallel to its orbital plane around the Sun. This extreme tilt causes Uranus to have extreme seasons, with each pole experiencing 42 years of continuous daylight followed by 42 years of darkness. This unique characteristic sets Uranus apart from the other planets in our solar system.

     A planet around a binary  star system is not suitable for life because

    • It lies out of the habitable zone

    • Planets don't orbit binary star systems

    • It'll have an unstable orbit

    • It'll receive too much heat

    Correct Answer
    A. It'll have an unstable orbit
    Explanation
    A planet around a binary star system is not suitable for life because it'll have an unstable orbit. The gravitational forces exerted by two stars can cause significant variations in the planet's orbit, leading to extreme temperature fluctuations and potential collisions with other celestial bodies. These unstable conditions make it difficult for life to thrive and sustain on such a planet.
