Thermosphere

Real World Example

Imagine trying to keep warm on a chilly night with just a thin blanket. This situation is similar to how the thermosphere functions, as it’s the uppermost layer of Earth’s atmosphere where temperatures can soar but the air is so thin that it doesn't feel hot. Just as the thin blanket provides minimal insulation despite the potential warmth, the thermosphere contains very few air molecules, meaning even though it's heated by the sun, the sparse air can't effectively transfer heat to make you feel warm.
