Study Notes
Elevation
- Elevation is the height above or below a fixed geographic reference point.
- The Earth's sea level is usually used as the reference point.
- In some cases, the ground level is used as the reference point instead.
- Elevation is crucial in everyday life.
Importance of Elevation
- Elevation is used in engineering to determine the center of gravity.
- Elevation is used to determine the type of materials to be used in engineering projects.
Human Adaptation to Environment
- Humans adapt to their environment, with variations in adaptation depending on elevation.
- The majority of the world's population (over 50%) lives in coastal regions with elevations of 500 feet or less.
- The people of Tibet in Central Asia are adapted to living at high elevations, specifically 17,500 ft.
- At high elevations in Tibet, crops cannot grow due to the harsh environment.
- The oxygen level is extremely thin at high elevations in Tibet, requiring unique adaptations to survive.
