Question

what is the relationship between temperature and altitude in the troposphere?
as altitude increases, temperatures fluctuate up and down.
as altitude increases, temperatures remain the same.
as altitude increases, temperature increases.
as altitude increases, temperature decreases.

Explanation:

Step1: Recall the properties of the troposphere

In the troposphere, as altitude increases, the air becomes less dense. The main source of heat in the troposphere is the Earth's surface. As we move away from the surface (increase in altitude), there is less heat absorption.

Step2: Analyze the temperature - altitude relationship

Since the heat source (Earth's surface) is below, as we go up (increase altitude), the temperature decreases.

Answer:

As altitude increases, temperature decreases.
