Bathymetry
is the measurement of ocean depths and the charting of the shape or topography of the ocean floor. Today’s technology—particularly sonar, satellites, and submersibles—allows scientists to study the ocean floor in a more efficient and precise manner than ever before.
What is the topography of the ocean floor?
Ocean floor topography refers to
the different forms in which the ocean floor bottom can exist
. You may perceive the ocean floor to be flat and sandy like the beach, but the truth is there are many different surfaces.
Is the measurement of ocean depths and the charting of the topography of the ocean floor Group of answer choices?
What is
bathymetry
? Bathymetry is the measurement of ocean depths and the charting of shape, or topography, of the ocean floor. Determining bathymetry involves measuring the vertical distance from the ocean surface down to the mountains, valleys, and plains of the seafloor.
Is the study of the depth of the oceans and the topography of the sea floor?
Bathymetry
(pronounced /bəˈθɪmətriː/) is the study of underwater depth of ocean floors or lake floors. In other words, bathymetry is the underwater equivalent to hypsometry or topography. … The global bathymetry is sometimes combined with topography data to yield a Global Relief Model.
What did satellite measurements show occurs to the ocean surface over a seamount on the ocean floor?
What happens to the ocean water over a seamount on the ocean floor when measured from a satellite?
The ocean water rises up to form a mound based on the mass of the seamount
.
What are 4 types of ocean floor?
Features of the ocean floor include the
continental shelf and slope, abyssal plain, trenches, seamounts, and the mid-ocean ridge
.
What is bathymetric curve?
A bathymetric chart is
a type of isarithmic map that depicts the submerged topography and physiographic features of ocean and sea bottoms
. Their primary purpose is to provide detailed depth contours of ocean topography as well as provide the size, shape and distribution of underwater features.
What are the three major topographic units of the ocean floor?
Physiography and bathymetry (submarine landscape) allow the sea floor to be subdivided into three distinct provinces:
(1) continental margins, (2) deep ocean basins and (3) mid-oceanic ridges
.
What are the two main topography of the ocean floor?
The main features of the Pacific Ocean floor are
the continental slopes
, which drop from about 200 m to several thousand metres over a distance of a few hundred kilometres; the abyssal plains — exceedingly flat and from 4,000 m to 6,000 m deep; volcanic seamounts and islands; and trenches at subduction zones that are …
What is the ocean floor called?
The ocean floor is called
the abyssal plain
. Below the ocean floor, there are a few small deeper areas called ocean trenches. Features rising up from the ocean floor include seamounts, volcanic islands and the mid-oceanic ridges and rises.
What is depth of sea?
The average depth of the ocean is
3,700 meters (12,100 feet)
. But the deepest part ever recorded is located in the western part of the Pacific Ocean, in the Mariana Trench, at a depth of around 11,000 meters (36,200 feet). Bathymetry is the scientific term for measuring the depth of water in oceans, lakes and rivers.
What are the 3 regions of the ocean floor?
The ocean floor or seabed can be divided into three major regions:
the continental margins, abyssal plains, and mid-ocean ridges
.
What is the deepest ocean depth?
Then explain to students that the Mariana Trench is the deepest part of the ocean and the deepest location on Earth. It is
11,034 meters (36,201 feet)
deep, which is almost 7 miles.
Can satellites see underwater?
Satellites can “see the sea” in ways that are otherwise impossible
. The Geostationary Operational Environmental Satellite-16 (GOES-16) is the first of NOAA’s next generation of geostationary weather satellites. Among the many missions of this satellite, it will collect ocean and climate data.
What are the most prominent features on the ocean floor?
The most prominent features of ocean basins are
the mid-ocean ridges
, which form underwater moun- tain ranges that run along the floors of all oceans. Mid-ocean ridges rise above sea level in only a few places, such as in Iceland. Mid-ocean ridges form where plates pull away from each other.
How well can satellites?
Optical image reconnaissance satellites use a charge coupled device (CCD) to gather images that make up a digital photograph for transmission back to Earth from an altitude of about 200 miles. … They have an imaging resolution of 5-6 inches, which means they can see
something 5 inches or larger on the ground
.
