hypsographic curve
ferentiated polyps known as the dangerous Portuguese man-of-war,
Physalia.
hypersaline waters with salinity considerably higher than normal seawater.
Examples are the brines at the bottom of the Red Sea, and brines in narrow
depressions in the sea floor of the East Mediterranean, e.g., the Tyro and
Bannock Basins. --7salinity crisis.
hypertonic adjective to denote that a solution has a higher osmotic concentration than that with which it is compared. It is a useful expression to indicate
the direction of passive water transport by osmosis: a hypertonic solution
will gain water from the adjacent hypotonic solution.
hypocenter an earthquake focus; the point at which an earthquake originates. The
projection on the surface of the earth is the epicenter.
hypolimnion the waterlayer in lakes below the seasonal thermocline.
hypotonic adjective to denote that a solution has a lower concentration of dissolved solutes than those present in another solution. When two fluid compartments are adjacent to each other the space with the hypotonic concentration will lose water and (if the separating barrier is permeable) gain
solutes (--7hypertonic).
hypsographic curve (hypsometric curve) cumulative frequency profile representing the statistical distribution of the absolute or relative areas of the earth's
solid surface at various elevations above, or depth below, a given datum, usually sea level. The curve is bimodal with the modes at + 100 m and -4700 m,
which reflects the two different parts of the earth's crust: continents and
ocean floor. The upper mode is at low altitude above sea level because of
subaerial erosion and sedimentation. The intermediate zone, starting at
-200 m and ending at ca. 3500 m, corresponds to the transition between
continents and ocean floor (generally at the continental slope).
