Height above sea level
by Nicola JELITTO
1. Mt. Everest is the highest elevation on earth but not the highest spot above sea level.Volcano Mauna Kea, in the U.S. state of Hawaii, would be higher than Mt. Everest if measured from sea level. Mauna Kea stands 10,203 meters high from the ocean floor, but rises only 4,207 meters above sea level.
2. Sea level is the base level for measuring elevation and depth on Earth.
3. The higher you go the colder it gets, The lower you go the warmer it gets.
4. Because the ocean is one continuous bodies of water, it's surface is mostly the same level throughout the world. However winds, currents, river discharges, and variations in gravity and temperature stop the sea surface from being truly level.
5. As you increase in elevation, there is less air above you because the pressure decreases. As the pressure decreases, air molecules spread out further and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.
6. Temperature is Measured in Degrees Celsius.
