what happens to the light as the ocean increases in depth explain
The intensity of sunlight decreases rapidly with depth. The depth of the water not only affects the colors of light that are noticeable underwater, it also affects the intensity, or amount of light. Within the first 10 m, water absorbs more than 50 percent of the visible light energy (Fig. 9.9).
Why is there little to no light as you go deeper into the ocean?
The ocean is very, very deep; light can only penetrate so far below the surface of the ocean. As the light energy travels through the water, the molecules in the water scatter and absorb it. At great depths, light is so scattered that there is nothing left to detect.
What happens to the amount of pressure in the ocean the deeper it gets?
The deeper you go under the sea, the greater the pressure of the water pushing down on you. For every 33 feet (10.06 meters) you go down, the pressure increases by one atmosphere . Many animals that live in the sea have no trouble at all with high pressure.Feb 26, 2021
What happens to the amount of light in the ocean the deeper it gets?
The intensity of sunlight decreases rapidly with depth. The depth of the water not only affects the colors of light that are noticeable underwater, it also affects the intensity, or amount of light. Within the first 10 m, water absorbs more than 50 percent of the visible light energy (Fig. 9.9).
Does light penetrate deeper in the ocean?
Light in the ocean decreases with depth, with minimal light penetrating between 200-1,000 meters (656-3,280 feet) and depths below 1,000 meters receiving no light from the surface.
How does light penetrate the ocean?
When sunlight strikes the ocean, some of it reflects off the surface back into the atmosphere. The amount of energy that penetrates the surface of the water depends on the angle at which the sunlight strikes the ocean. Near the equator, the sun's rays strike the ocean almost perpendicular to the ocean's surface.
How far can light penetrate in open ocean?
Light in the ocean decreases with depth, with minimal light penetrating between 200-1,000 meters (656-3,280 feet) and depths below 1,000 meters receiving no light from the surface.
Does visible light penetrates deeper in shallow water?
Fig. 9.7. Visible colors of light penetrate differently into the ocean depths, as seen in this image depicting light penetration in Lake Superior. Longer wavelengths such as red are absorbed at a shallower depth than shorter wavelengths such as blue, which penetrates to a deeper depth.
Why does light penetrate deeper in open ocean?
Water in the open ocean appears clear and blue because it contains much less particulate matter, such as phytoplankton or other suspended particles, and the clearer the water, the deeper the light penetration.
What happens to light when it enters the ocean?
Light Penetration. A certain amount of incoming light is reflected away when it reaches the ocean surface, depending upon the state of the water itself. If it is calm and smooth, less light will be reflected. If it is turbulent, with many waves, more light will be reflected.
How does the ocean absorb light?
The most important light-absorbing substance in the oceans is chlorophyll, which phytoplankton use to produce carbon by photosynthesis. Due to this green pigment – chlorophyll – phytoplankton preferentially absorb the red and blue portions of the light spectrum (for photosynthesis) and reflect green light.
Why does light stop in the ocean?
The ocean is very, very deep; light can only penetrate so far below the surface of the ocean. As the light energy travels through the water, the molecules in the water scatter and absorb it. At great depths, light is so scattered that there is nothing left to detect.
How does light work in the ocean?
Seawater absorbs light much more strongly than air does, but visible light is made up of a rainbow of different wavelengths, each perceived by us as a different color. Blue light penetrates farther into seawater (giving the ocean its distinctive color).Oct 15, 2004
