Altitude
Context Matters
Altitude is used differently when talking about flying objects vs mountains.

The mountain's altitude rarely changes, but a helicopter's altitude can vary.
Relative Reference
Altitude is not absolute; it's relative to sea or ground level.

The hiker's campsite was at an altitude of 2,000 feet above sea level.
Effects on Body
High altitudes can affect breathing and cause sickness due to thinner air.

Many climbers face altitude sickness when ascending too quickly.
