    a)    Convection
    b)    Conduction
    c)    Radiation
    d)    Scattering

    Ans. (a) Convection

    The trade winds are caused by convection of air currents and the Earth's rotation. The air near the Equator gets hot and moves towards each pole, respectively, and it is deflected by the Coriolis Effect (the spin of the Earth).

    3.    Identify the supercontinent that existed  150 million years ago in the southern hemisphere.

    a)    Laurasia
    b)    Pangea

    Gondwana was a supercontinent that formed from the unification of several cratons in the Late Neoproterozoic, merged with Laurussia in the Carboniferous to form Pangaea, and began to fragment in the Mesozoic. It was the largest continental landmass on Earth, covering an area of 64% of today's continents. Located in the Southern Hemisphere, it incorporated several modern landmasses, including Antarctica, South America, Africa, Madagascar, and Australia, as well as the Arabian Peninsula and the Indian subcontinent, which have now moved entirely into the Northern Hemisphere.

    Ichthyosaurs species are large marine reptiles, belonging to the order known as Ichthyosauria or Ichthyopterygia. Fossil evidence reveals that the species first appeared around 250 million years ago and at least one species survived until about 90 million years ago.

    5.    The deflection of winds to the right in the northern hemisphere is primarily due to

    a)    Revolution of the Earth
    b)    Rotation of the Earth
    c)    Smaller land to Ocean ratio
    d)    All the above

    Ans. (b) Rotation of the Earth

    The Coriolis Effect is responsible for the deflection in global wind patterns. The anticlockwise rotation of the Earth deflects winds to the right in the northern hemisphere and to the left in the southern hemisphere.

    6.    Son is a tributary of

    a)    Ganga
    b)    Godavari
    c)    Krishna
    d)    Cauvery
