Consider the following statements regarding Terrestrial Radiation:
1. The earth after being heated by the sun radiates energy to the atmosphere in the
form of short waves.
2. The amount of heat received in the form of insolation is more than the amount
lost by the earth through terrestrial radiation.
Which of the statements given above is/are correct?CorrectAnswer: D
• The earth after being heated itself becomes a radiating body and it radiates energy to the atmosphere in long wave form.
• The earth as a whole does not accumulate or loose heat. It maintains its temperature. This can
happen only if the amount of heat received in the form of insolation equals the amount lost by the
earth through terrestrial radiation.IncorrectAnswer: D

Consider the following statements with regard to coriolis force:
1. It deflects the wind to the right direction in the northern hemisphere.
2. It does not depend on the velocity of wind.
Which of the statements given above is/are correct?CorrectAnswer: A
• The Coriolis deflection is related to the velocity of the object, the motion of the Earth, and the
latitude.
• The rotation of the earth about its axis affects the direction of the wind. This force is called the Coriolis force after the French physicist who described it in 1844. It deflects the wind to the right direction in the northern hemisphere and to the left in the southern hemisphere.IncorrectAnswer: A
