Question

 Consider the following statements regarding HEATING AND COOLING OF ATMOSPIILIU:
1. Convention is important in heating the lower layers of the atmosphere.
2. The convention transfer of energy is confi ned only to the troposphere.
3. 'Ioo' is the outcome of advection process.
Identify the correct statements :

• A. 1 and 2 only
• B. 2 and 3 only
• C. All 1,2 and 3 are correct
• D. All 1,2 and 3 are incorrect

Answer 1

The Correct Option is B

To determine the correct statements about the heating and cooling of the atmosphere, let's analyze each statement individually:

1. Statement 1: "Convention is important in heating the lower layers of the atmosphere."
   The term "convention" here seems to be a typographical error. The correct term should be "convection." Convection is indeed important in heating the lower layers of the atmosphere, as it involves the vertical movement of air, which plays a significant role in heat transfer within the troposphere. Thus, statement 1 is correct if we correct the terminology to "convection."
2. Statement 2: "The convention transfer of energy is confined only to the troposphere."
   Correcting "convention" to "convection," this statement asserts that convection transfer of energy occurs primarily in the troposphere, which is true because convection currents are prevalent in this layer. Therefore, statement 2 is correct.
3. Statement 3: "'Ioo' is the outcome of advection process."
   The term "'Ioo'" appears unclear, possibly intended to mean "loo," which refers to the hot, dry winds that blow over North India during the summer. These winds are indeed the result of advection, where horizontal transfer of air masses leads to changes in temperature and pressure. Thus, statement 3 is correct if 'Ioo' correctly interprets to "loo."

Based on the analysis, statements 2 and 3 are correct, making the correct answer "2 and 3 only."
