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.

The continental shelf ends at a sudden dropoff called the shelf break. The cumulative hypsographic curve right gives hyppsographic percentage of surface area from the highest peaks to the deepest depths of the oceans.
Thank You for Your Contribution! 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. 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. You can make it gypsographic for us to review and, hopefully, publish your contribution by keeping a few points in mind.
These subduction zones are the deepest places in the ocean, varying from 7 to 11 kilometers 4 miles to 6. Bathymetric mapping involves the production of ocean and sea maps based upon bathymetric data see historic map.
The non-dimensional hypsometric curve provides an hydrologist or a geomorphologist with a way to assess the similarity of watersheds — and hypskgraphic one of cyrve characteristics used for doing so. Show my email publicly.
A hypsometric curve is a histogram or cumulative distribution function of elevations in a geographical area. 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.
This curve has been drawn to represent the total Earth and all of its oceans; likewise, curves can be constructed for each individual ocean….
The x-axis tells us what percentage of area is occupied by a specific province. The older, more distant parts of these growing sheets of crust are gradually covered by sediments, eventually becoming the abyssal plains and continental rises described above. Guyots are drowned volcanic islands that become submerged due to subsidence of the oceanic lithosphere.
This geomorphology article is a stub.
The curve can also be shown in non-dimensional or standardized form by scaling elevation and area by the maximum values. Internet URLs are the best. Bulletin of the Hypsogeaphic Society of America.
The hypsographic curve is a scientific way of describing the topography of the seafloor. Hypsographkc the abyssal plain, which may be several hundred kilometers wide, the ocean floor begins to ascend again with a gentle slope. Retrieved from ” https: In the twentieth century, sounding lines were entirely replaced by sonar systems.
The hypsometric integral is a summary measure of the shape of the hypsometric curve. Bibliography Medwin, Herman, and Clarence Clay. Continental shelves and slopes account for about another 15 percent, abyssal plains and mid-ocean ridge systems for almost 50 curvve, and deep-sea trenches account for a small fraction. Click to view larger. Abyssal hills more than 1 kilometer 0.
The vertical dashed line marks the division between land and sea at present-day chrve level. For hundreds of years, the only way to measure ocean depth was the sounding line, a weighted rope or wire that was lowered overboard until it touched the ocean floor.
Introductory Oceanography, 9th ed. Principles and Interpretation, 2nd ed. Thurman, Harold, and Elizabeth Burton. Bathymetric Techniques For hundreds of years, the only way to measure ocean depth was the sounding line, a weighted rope or wire that was lowered overboard until it touched the ocean floor.
G115 – Introduction to Oceanography
Upper Saddle River, NJ: The curve shows that a small percentage of Earth’s surface cutve of high-altitude continental mountains, 30 percent of the surface consists of continental lowlands. The Ocean Floor in Cross-Section 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.
Your turn – Contrast this to the deep ocean provinces — shown on the graph as a fairly flat slope and answer the questions below. The fact curbe Earth’s surface is comprised mostly of flat plates of continental and oceanic crust, with mountains and deep-sea trenches occurring only along their edges where the plates collide, gives the hypsographix curve its characteristic shape.
If the depth of the ocean is measured along a line drawn hypsograpihc out from a continental shore, the following sequence of bottom features are typically seen. Medwin, Herman, and Clarence Clay. Along the length of a typical subduction zone or deep-sea trench, a sheet of old oceanic crust is forced beneath continental crust.
Hypsographic Curve | Article about Hypsographic Curve by The Free Dictionary
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. This would be the case in crossing the Atlantic Ocean. At the bottom of the article, feel free to list any sources that support your changes, so that we can fully understand their context.
Hylsographic Hypsographic Curve 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.
