What happens to temperature as altitude increases in the trophosphere?

• A. Temperature remains constant
• B. Temperature increases
• C. Temperature decreases
• D. Temperature fluctuates

Answer: (C)

In the troposphere, which is the lowest layer of Earth's atmosphere, temperature typically decreases with increasing altitude. This decrease occurs due to several factors, primarily related to the way that solar energy is absorbed and radiated by the Earth's surface.

At lower altitudes, the ground absorbs sunlight and heats up, warming the air directly above it. As you move higher in altitude, there is less air above to trap that heat, leading to a drop in temperature. This phenomenon is also influenced by the decrease in air pressure and density with altitude, which affects the capacity of the air to hold heat.

This trend continues up to the tropopause, where the troposphere transitions to the stratosphere. It’s important to note that while there may be variations due to weather patterns and local conditions, the general rule in the troposphere is that temperature decreases steadily with height.
