What is the highest elevation continent on Earth?
It’s that ice sheet, with an average thickness of 2.16 km that helps to make Antarctica the highest elevation continent on Earth. Without the ice cover, Antarctica would rank as one of the lowest elevation continents on Earth.
What is the average elevation of the earth's surface?
According to Earth - Wikipedia, “The elevation of the land surface varies from the low point of −418 m at the Dead Sea, to a maximum altitude of 8,848 m at the top of Mount Everest. The mean height of land above sea level is 840 m.” Beside above, how does the average depth of the oceans compared to the average elevation of the continents?
How much higher is the ocean floor than the average elevation?

What is the average continental height?
0.8 kmAs shown on the right-hand figure, the average height of the continents is 0.8 km, and the average depth of the oceans is 3.7 km. This provides us with information about the average thickness and density of the continental and oceanic crust.
What is the average land elevation?
The mean elevation of Earth is −2441 m relative to the WGS84 spheroid based on the uncorrected Etopo1_Bed (Amante and Eakins 2009) global topography (Rowley 2013) and the GIA-corrected Etopo1 bedrock topography used in the present analysis. This elevation represents the mean height of the solid, nonwater Earth.
What continent has the highest average elevation?
AntarcticaAntarctica is the highest continent on Earth: average elevation is 8,200ft (2500m). The elevation at the South Pole is 9,300ft (2835m).
What is the average elevation of the ocean basins?
To a first approximation, Earth is a composite of elevated continents and deep ocean basins. We use the present-day sea level to reference topography and bathymetry and the average elevation of the continents is 840 meters, the average depth of the oceans is 3800 meters.
What continent has the lowest elevation?
The Land of Snow and Ice Without the ice cover, Antarctica would rank as one of the lowest elevation continents on Earth [1]. The Byrd Subglacial Basin in western Antarctica, the lowest point on any of the Earth's continental plates [2], lies 2,538 meters below sea level.
Which country has the highest average elevation?
Bhutan ranks number one in the world in terms of average land elevation above sea level (10,760 feet).
Which country has the lowest average elevation?
1. Maldives, 1.8 meters (6 feet) The Maldives is a country made up of 1,200 small coral islands, known as atolls, in the North Indian Ocean.
What is the average elevation of England?
The United Kingdom is comparatively low at an average elevation of 162 meters above sea level. The highest mountain peak (Ben Nevis) is at 1,345 meters.

Why are the continents above the ocean floor?
While the ocean basins lie much lower than sea level, the continents stand high—about 1 km (0.6 mile) above sea level. The physical explanation for this condition is that the continental crust is light and thick while the oceanic crust is dense and thin.
What is the average depth of the ocean?
The average ocean depth is 3.7 kilometers (2.3 miles). The average depth of the ocean is about 3,688 meters (12,100 feet).
What percentage of the Earth is covered by ocean?
70 percentThe ocean covers more than 70 percent of the surface of our planet.
How high is the land above sea level?
The mean height of land above sea level is 840 m. ”.
How deep are ocean floors compared to continents?
Beside above, how does the average depth of the oceans compared to the average elevation of the continents? The ocean floors are about 4 times as deep, on average, than the average elevation of the continents above sea level.
How high is the land above sea level?
The mean height of land above sea level is 840 m .”
What is mean sea level?
Mean Sea Level (MSL) is an average level of the surface of one or more of Earth’s oceans (or seas) from which heights such as elevations may be measured.
What would happen if we climb to the top of a mountain?
If we climb to the top of a mountain, that column is not as massive, so there is less pressure at the bottom of the column. For example, if we were at the peak of Mt. Everest, the atmospheric pressure would be about 1/3 of what it is at sea level.
How deep is the ocean?
The average ocean depth is 3700m, covering 71% of the planet.
What is the atmospheric pressure at sea level?
Atmospheric pressure at that sea level would be somewhere around 1.33 atm or 1347 hPa.
How much does a column of air weigh?
As we walk around, there is a column of air above us, pressing down on us. At sea level, that column is about 50 miles high and weighs 14.7 pounds per square inch.
Which continent has the highest elevation?
It’s that ice sheet, with an average thickness of 2.16 km that helps to make Antarctica the highest elevation continent on Earth.
What is the highest continent in the world?
The Highest Continent. Much of the imagery presented in the news about Antarctica is taken from aerial and satellite imagery. As a snow and ice covered continent, Antartica can look flat when viewed from space. With an ice sheet covering all but about 0.04 percent of the continent [1], Antarctica is often referred to as the “the land ...
What is the highest point on the South Pole?
The South Pole is located at an elevation of 2,800 meters (9,300 feet). The highest elevation in Antarctica is Mount Visson, with a peak of 4,892 meters (16,050 feet). The lowest point on Antarctica is Deep Lake, Vestfold Hills in East Antartica with a depth of -50 meters (−160 feet). A closed lake, Deep Lake is hypersaline.
What is the land of snow and ice?
With an ice sheet covering all but about 0.04 percent of the continent [1], Antarctica is often referred to as the “the land of snow and ice”. The continent holds 90% of the world’s ice (29 million cubic kilometers) and about 80% of its fresh water. Antartica ’s thick covering of ice and snow can make the continent appear quite flat.
How high is the average continent?
Because average ocean water depth was 3.902 km, this puts the average continent surface elevation 680 m above the sea surface, which is 155 m less than the present value of elevation of 835 m, so that the average continent elevation relative to the sea surface is 155 m higher now than at 65 Ma.
What is the continental crust?
Abstract. [1] To the simplest approximation, Earth's continental crust is a floating aggregate on the planet's surface that is first attracted to subduction zones and, upon arrival, thickened by mountain building (then producing some extension). Thickened regions are thinned again by erosion.
Who edited the book Continental Margins?
U. ( 1974 ), Continental margins, freeboard and the volumes of continents and oceans through time, in The Geology of Continental Margins, edited by A. E. M. Nairn, and F. G. Stehli, pp. 45 – 58, Springer, New York .
