10 Questions
What is elevation used to determine in engineering?
The center of gravity
What is elevation typically measured from in most cases?
Sea level
What is the significance of elevation in everyday life?
It plays a crucial part
What can be used as an alternative reference point to sea level?
Ground level
What is elevation used to determine in addition to the center of gravity in engineering?
The type of materials to be used
How do humans adapt to different environments?
Humans adapt to their environment, with some adapted to higher elevations and others to lower elevations.
What percentage of the world's population lives in coastal regions?
A majority of the world's population lives in coastal regions with elevations of 500 feet or less.
What is unique about the people of Tibet?
The people of Tibet are adapted to living at high elevations, specifically 17,500 ft.
What are the conditions like at 17,500 ft. in Tibet?
At 17,500 ft. in Tibet, the oxygen is extremely thin and crops cannot grow.
What is an example of a region with a high-elevation adapted population?
Tibet in Central Asia is an example of a region with a high-elevation adapted population.
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.
Elevation refers to the height above or below a fixed geographic reference point, crucial in engineering to determine the center of gravity and materials used.
