The height of the troposphere increases during the summer season. This occurs because higher temperatures cause the air near the surface to expand and rise more vigorously. The resulting increase in thermal energy pushes the tropopause—the boundary between the troposphere and stratosphere—to a higher altitude. In contrast, colder winter temperatures cause the air to contract, lowering the layer’s overall height. ANSWER: (C) Summer season

The vertical extent of the troposphere is directly tied to the temperature of the air. During the summer, the Earth’s surface receives more intense solar radiation, leading to significant warming of the lower atmosphere. As air molecules gain energy, they move further apart, causing the air to expand and occupy more volume. This thermal expansion pushes the upper limit of the troposphere higher into the sky. Conversely, during winter, the air cools and becomes denser, leading to a contraction of the layer. This seasonal fluctuation is a key factor in understanding regional weather and atmospheric pressure changes.
