Elevations

The height of a mountain peak above sea level is called its elevation.

The altitude above sea level in Lethbridge, Alberta, Canada, is approximately 929 meters (3,048 feet).

a mountain structure is an example of elevation

The highest elevation in the Gulf Coastal Plain region is about 900 feet above sea level, found in some parts of eastern Texas and western Louisiana. The majority of the Gulf Coastal Plain, however, is characterized by low-lying terrain and elevations ranging from sea level to a few hundred feet above sea level.

On average it is 10 feet.

plateu

Plateaus generally have higher elevations compared to plains. Plateaus are elevated flatlands that rise above surrounding areas, while plains are vast, mostly level areas at a low elevation.

what is the lowest point of elevation in the United States

It has an average height of 853 feet above sea level.

No. It changes negligably from the standard ~21% regardless of elevation. (at any elevation you can survive at anyway) :p The actual amount of available oxygen does change, due to a decrease in atmospheric density as elevation increases. For example: at 17,700ft (apparently a common Mt. Everest base camp) the air density is approximately 51% of the density at sea level. So you COULD express it as 51% of ~21%, which would be about 10.71%.

Kandahar is located at an elevation of approximately 1,010 meters (3,310 feet) above sea level.

Camp Bastion in Helmand Province is approximately 2900ft or 884 metres above sea level

Abbotsford, BC is above sea level. It is located approximately 59 meters (194 feet) above sea level.

6.4˚C per 1000 m elevation gain or 3.5˚F for 1000 ft elevation gain

The land elevation along the coastal plain varies but generally ranges from sea level to a few hundred feet above sea level. The elevation gradually increases as you move further inland from the coast.

Switzerland has the highest average elevation in Europe, with most of its land being above 1,000 meters. The Swiss Alps contribute to the country's high average elevation.

well.logically it just makes sense that since there is less oxygen above sea level (mt Everest roughly 1/3 of the oxygen at sea level) that there would be more oxygen below sea level.

note: this is completely hypothetical and has no scientific backing whatsoever

The word is elevation.

There are actually two states with areas below sea level - California and Louisiana.

the climax

The highest point above sea level in Prince Edward Island is 152 meters (499 feet) and is located in the community of Springton.

There is a big difference between height and elevation. Height is how tall something is. Elevation is how far above sea level something is.

3672 feet above sea level
