Why is it colder the higher you are above sea level?

The temperature of the air around Earth is directly related to the amount of radiated heat from the sun hitting the Earth's surface, thereby warming it.
Hot air rises and cools. It cools because the upper atmosphere is a lot cooler than closer to Earth.
The upper atmosphere is cooler because the temperature in space is extremely cold - approximately minus 270 degrees celsius or minus 455 degrees fahrenheit. Basically, the nearer you get to space, the cooler it will get!
