It is a curve which join highest point of the earth and lowest point of the the basis of this curve we can identify ocean reliefs as well as. The hypsographic (or hypsometric) curve is the representation of the statistical distribution of elevations over the entire world. In the areas which are covered. Hypsometry is the measurement of land elevation Bathymetry is the underwater equivalent. Hypsography of the Earth. Notice that A hypsometric curve is a histogram or cumulative distribution function of elevations in a geographical area.

Most bathymetric maps show isobaths lines of equal depths as contours for the body hypsogaphic water. If you prefer to suggest your own revision of the article, you can go to edit mode requires login.

The vertical dashed line marks the division between land and sea at present-day sea level. The oceans begins, of course, at the shore, the irregular boundary where the surface of a continent descends first to sea level and then beneath it.

These growing hypsographuc of crust have the effect of forcing the distant continents farther apart, a process called sea-floor spreading. The average width of a continental shelf is 70 kilometers 43 miles. The elevation features of the ocean floor—shelves, slopes, rises, plains, ridges, and trenches—are quantitatively summarized by oceanographers, along with the distribution of dry land at different altitudes, in a graph called the hypsographic curve see the figure.

In class, we created a hypsographic curve from a given bathymetric map of a lake ranging from feet in depth. Beyond the abyssal plain, which may be several hundred kilometers wide, the ocean floor begins to ascend again with a gentle slope.

What percent of the earth’s surface is “deep” ocean and how deep is “deep” ocean considered?

Hypsometry – Wikipedia

The non-dimensional hypsometric curve provides an hydrologist or a geomorphologist with a way to assess the similarity of watersheds — and is one of several characteristics used for doing so. For many miles out, the ocean is only a few hundred feet deep and gets deeper quite slowly i. On other planets within this solar system, elevations are typically unimodalowing to the lack of oceans on those bodies. From this valley, new oceanic crust is constantly being extruded from Earth’s mantle by processes not yet fully understood.

Hypsometric curve

This area is the flank of the mid-ocean ridge, a long, undersea mountain chain curge usually extends down the middle of the ocean.

The x-axis tells us what percentage of area is occupied by a specific province.

When drawn as a 2-dimensional histogram, a hypsometric curve displays the elevation y on the vertical, y-axis and area above the corresponding elevation x on the horizontal or x-axis.

Beyond the rift valley, the depth sequence described above is observed hylsographic reverse: The most popular type hypsographi bathymetric maps are ones on which lines of equal depths called isobaths are represented. It is composed of fine-grained continental sediments silt and clay washed down the many submarine canyons that notch the continental slope.

Continental shelves and slopes account for about another 15 percent, abyssal plains and mid-ocean ridge systems for almost 50 percent, and deep-sea trenches account for a small fraction. A hypsometric curve is essentially a graph that shows the proportion of land area that exists at various curbe by plotting relative area against relative height.

Water, a substance composed of the chemical elements hydrogen and oxygen and existing in gaseous, liquid,…. If we look at the y-axis of the graph, we can see that continental margins are found from 0 to 4 km depth in the ocean.

It was also difficult to tell when the sounding line had actually touched bottom. The y-axis tells us the elevation of that province.

Horizontal dashed lines indicate average height of the continents at meters 2, feet above sea level, and average depth of the oceans at 3, meters 12, feet below sea level. These subduction zones are the deepest places in hypsogeaphic ocean, varying from 7 to 11 kilometers 4 miles to 6.

Any text you add should be original, not copied from other sources. Bathymetric maps represent the ocean depth as a function of geographical coordinates in the same way topographic maps represent the altitude of Earth’s surface at different geographic points. The cumulative hypsographic curve right gives the percentage of surface area from the highest peaks to the deepest depths of the oceans.

Internet URLs are the best. Discover some of the most interesting and trending topics of Using a square cutout of the scale representing 10, square meters and precise cutouts of the lake following each depth contour, the area at each depth was determined through a weight-area relationship 0.

Guyots are drowned volcanic islands that become submerged due to subsidence of the oceanic lithosphere. Subsequent research using two-dimensional landscape evolution models has called the general applicability of this fit into question, [5] as well as the capability of the hypsometric curve to deal with scale-dependent effects.
