In the troposphere, as altitude increases, the temperature decreases. This is due to the fact that the troposphere is the lowest layer of the Earth's atmosphere where weather events occur. As you move higher in the troposphere, the air becomes less dense, leading to a decrease in temperature.
Here's a simple breakdown:
1. Altitude increases in the troposphere.
2. As altitude increases, the temperature decreases.
3. This is because the air becomes less dense at higher altitudes, causing the temperature to drop.
Therefore, the correct answer to the question is:
B. decrease
