i.e. up a mountain or hill?
The way the atmosphere gets to be the temperature that it is:
- Sunlight travels through the atmosphere, but doesn’t heat it directly.
- Sunlight warms the Earth’s surface
- The Earth’s surface warms the air
- The warm air rises
However, as the warm air rises it expands and cools, and as a result the temperature falls by around 6 °C for every 1000 metres height in the atmosphere.
