As long as there is adequate oxygen there is no ideal altitude
At high altitude the level of oxygen is very less as compared to that of the lower region so, the process of respiration causes the red blood cell more active around the cheek. This causes to seem the red cheek of people living in high altitude.
Altitude describes an object's position relative to sea level. An object in a position higher than sea level would have a positive altitude, sea level would have an altitude of zero, and any object below sea level would have a negative altitude.
It is called altitude. It is typically expressed as ASL (above mean sea level, or MSL). However, it can also be specified as AGL (Above the local Ground Level).
The altitude varies based upon the water level in the lake. The highest level was 6,229 feet and the average altitude is about 6,224 feet.
No, an altitude is a height above sea level.
Cabin Altitude is the 'Cabin pressure' in terms of equivalent altitude above sea level .
== == Science Major: Altitude is height above mean sea level (MSL) or true altitude, which means in reference to what sea level is on the ground, or height above ground level (AGL), which is also called absolute altitude, which means height above the ground with no reference to the ground's height above sea level. In example, if the sea level in a certain place is 100 feet and you are 250 feet above the ground, your altitude above sea level would be 350 feet, and your altitude above ground level would be 250 feet.
A level line is based on altitude. Altitude is the distance from sea level. Sea level is curved to the shape of the earth so a level line must be curved.
The rise of the sea level will make people living in sea level countries submerged in sea water.
No it is not
It is not, the highest altitude above Sea Level is achieved by the summit of Mt. Everest.
An altitude is measured from mean seal level on Earth. So asking what the planet's altitude is, is a nonsense question.
