Commonly abbreviated as D, depth is a measurement of how far back a three-dimensional object is . For example, measurements of an object, such as a computer monitor, are commonly measured as (D x W x H), short for Depth by Width by Height. In the illustration, the Z-axis is the depth.
How do you measure the depth of the ocean?
Use the following formula for measuring ocean depth. D = V Times 1/2 T D = Depth (in meters) T= Time (in seconds) V = 1507 m/s (speed of sound in water) Calculate the depth foe each of the times given below, using the formula above.
How do we measure the depth of the ocean?
The most common and fastest way of measuring ocean depth uses sound . Ships using technology called sonar, which stands for sound navigation and ranging, can map the topography of the ocean floor. The device sends sound waves to the bottom of the ocean and measures how long it takes for an echo to return.
What instrument measures depth?
A depth gauge is an instrument for measuring depth below a reference surface.
What is the 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 is an example of depth?
The vertical distance below a surface; the amount that something is deep. ... Depth is defined as the distance from top down or front to back, or the intensity of color or sound. An example of depth is a swimming pool being six feet deep. An example of depth is the darkness of a purple dress .
Does depth mean height?
Height vs Depth
Height is a measurement of the vertical magnitude of the object . Depth is also a measurement of the vertical magnitude of an object. These two terms may look like representing the same quantity.
Is length the depth?
As nouns the difference between depth and length
is that depth is the vertical distance below a surface ; the degree to which something is deep while length is the distance measured along the longest dimension of an object.
What is 6ft depth of water measured in?
A fathom is a unit of length in the imperial and the U.S. customary systems equal to 6 feet (1.8288 m), used especially for measuring the depth of water.
What is the unit for depth?
Fathom: The common unit of depth in the ocean for countries using the English system of measurement. It is six feet or 1.83 meters. It can also be used in expressing horizontal distance, since 120 fathoms is nearly equal to one-tenth of a nautical mile.
What instrument measures humidity?
The instrument used to measure relative humidity is the hygrometer . A variety of different digital and analog models exist, but you can build a simple version with your class. Known as the sling psychrometer, this hygrometer takes a measurement with a “wet bulb” thermometer and a “dry bulb” thermometer simultaneously.
What Colour is ocean depth?
The reason the ocean is blue is due to the absorption and scattering of light. The blue wavelengths of light are scattered, similar to the scattering of blue light in the sky but absorption is a much larger factor than scattering for the clear ocean water.
At what depth is the ocean dark?
It is sometimes referred to as the midnight zone or the dark zone. This zone extends from 1,000 meters (3,281 feet) down to 4,000 meters (13,124 feet) . Here the only visible light is that produced by the creatures themselves. The water pressure at this depth is immense, reaching 5,850 pounds per square inch.
What is the highest depth of the ocean?
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.
What is depth of description?
(also fullness of description), n. The level of detail about the contents of a collection in a finding aid or catalog record .
