Answer the following question given this paragraph: 

In the troposphere, temperature decreases with altitude. The troposphere gets some of its heat directly from the Sun. Most, however, comes from Earth's surface. The surface is heated by the Sun. Some of that heat radiates back into the air. This makes the temperature higher near the surface than at higher altitudes.


Q: What happens to temperature in the troposphere as the altitude increases?


A:
it decreases
