HYPSOGRAPHIC CURVE PDF

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.

Principles of Physical Oceanography. The resulting curve is shown below in Figure 1. Archived from the original on On Earth, the elevations can take on either positive or negative below sea level values, and are bimodal due to the contrast between the continents and oceans.

Hypsometry

The y-axis tells us the elevation of that province. Posted by Leah Moore at 2: The most popular type of bathymetric maps are ones on which lines of equal depths called isobaths are hjpsographic. On other planets within this solar system, elevations are typically unimodalowing to the lack of oceans on those bodies.

Fundamentals of Acoustical Oceanography. Twin sheets of fresh, hypsograaphic crust emerge from the mantle along the sides of the rift valley and flow slowly away from it in opposite directions.

Ocean-Floor Bathymetry

The continental shelf ends at a sudden dropoff called the shelf break. 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 would be the case in crossing the Atlantic Ocean. The curve can also be shown in non-dimensional or standardized form by scaling elevation and area by the maximum values.

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. 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.

Our editors will review what you’ve submitted, and if it meets our criteria, we’ll add it to the article.

Medwin, Herman, and Clarence Clay. Then compare your response to the correct answer.

Internet URLs are the best. A hypsometric curve is a histogram or cumulative distribution function of elevations in a geographical area.

The cumulative hypsographic curve right gives the percentage of surface area from the hyosographic peaks to the deepest depths of the oceans. Neumann, Gerhard, and Willard Pierson.

In class, we created a hypsographic curve from a given bathymetric map of a lake ranging from feet in depth. It was also difficult to tell when the sounding line had actually touched bottom.

This page was last edited on 13 Decemberat 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. Subsequent research using two-dimensional landscape evolution models has called the general hypsogrpahic of this fit into question, [5] as well as the capability of the hypsometric curve hypsogrwphic deal with scale-dependent effects. A hypsometric curve is essentially a graph that shows the proportion of land area that exists at various elevations by plotting relative area against relative height.

The abyssal plain is dotted with thousands of small, extinct volcanoes called abyssal hills.

You can help Wikipedia by expanding it. These growing sheets of crust have the effect of forcing the distant continents farther apart, a process called sea-floor spreading. From this valley, new oceanic crust is constantly being extruded from Earth’s mantle by processes not yet fully understood.

These subduction zones are the deepest places in the ocean, varying from 7 to 11 kilometers 4 miles to 6. This flat, wide margin is found around every continent and is known as the continental shelf.

In addition, Murray’s 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.
