Which among the following statements is/are correct about latitudinal heat balance?The amount of insolation received varies from latitude to latitude.Regions within the equator and 40° N and S latitudes are energy deficit regionsRegions beyond 40° N and S latitudes are energy surplus regionsSelect the correct code from the options given below:

• A. Only 1
• B. Only 1 & 3
• C. Only 2 & 3
• D. 1, 2 & 3

Answer: (A)

The amount of insolation received varies from latitude to latitude. The Regions within the equator and 40° N and S latitudes are energy surplus regions because they receive abundant sunlight and hence more heat will be gained than lost.The Regions beyond 40° N and S latitudes are energy deficit regions because they lose more heat than that gained from sunlight.
