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 hypsometric integral is a summary measure of the shape of the hypsometric curve. From this valley, new oceanic crust is constantly being extruded from Earth’s mantle by processes not yet fully understood. 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.
Twin sheets of fresh, mile-thick crust emerge from the mantle along the sides of the rift valley and flow slowly away from it in opposite directions. On Earth, the hysographic can take on either positive or negative below sea level values, and are bimodal due to the contrast between the hypsograpjic and oceans. Here, the ocean floor is marked by thousand-mile cracks called fracture zones that lie at right angles across the mid-ocean ridge.
Unfortunately, our editorial approach may not be able to accommodate all contributions. If you prefer to suggest your own revision of the article, you can go to edit mode requires login. In the hypsometric curve of the total Earth surface there exist two maxima of frequencies—at the metre yard and the 4,metre 5,yard elevations, which correlate with the mean level of the lowland continental areas and the deep-sea floor. A hypsometric curve is a histogram or cumulative distribution function of elevations in a geographical area.
hypsogrsphic Freeman and Company, The vertical dashed line marks the division between land and sea at present-day sea 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.
Newer Post Older Post Home. Not only was this method time-consuming, it was inaccurate; ship drift or water currents could drag the line off at an angle, which would exaggerate the depth reading. 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.
Click to view larger. This flat, wide margin is found hypsographci every continent and is known as the continental shelf. Please try again later.
On other planets within this solar system, elevations are typically unimodalowing to the lack of oceans on those bodies. The hypsographic curve shows the amount of Earth’s surface at various elevations and depths.
In addition, Hyosographic map gave birth to the idea of the Telegraphic Plateau, a submarine land formation from Canada to the British Isles, across which the first transatlantic cable was laid. Internet URLs are the best. 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.
The x-axis tells us what percentage of area is occupied by a specific province. Along the center of the mid-ocean ridge is the rift valley, a deep V-shaped notch.
You can make it easier for us to review and, hopefully, curbe your contribution by keeping a few points in mind. For many miles out, the ocean is only a few hundred feet deep and gets deeper hypsogrzphic slowly i. The hypsographic curve is a scientific way of describing the topography of the seafloor.

At the bottom of the article, feel free to list any sources that support your changes, so that we can fully understand their context. Beyond the rift valley, the depth sequence described above is observed in reverse: Help us improve this article!

Any text you add should be original, hupsographic copied from other sources. The average width of a continental shelf is 70 kilometers 43 miles.
