Consider a specific point on the surface of the earth (say Delhi). The temperature at a given time of day (say 12.00 Noon) will in general be higher in summer than in winter. This is because: [IAS 1993]

• A. the evaporation of water from atmosphere results in precipitation occurring in winter alone
• B. Sun-rays falling on the earth are inclined more towards the sun in winter
• C. the earth is closer to the sun in summer than in winter
• D. the axis of the earth is inclined more towards the sun in winter
