What color light does not penetrate 70 meters beneath the ocean surface?
Red light does not penetrate 70 meters beneath the ocean surface as it is quickly absorbed by water molecules.
How far does light penetrate underwater?
The depth light can penetrate underwater depends on water clarity and the angle of the sun. In clear ocean water, sunlight can penetrate up to 200 meters (656 feet). In murky or turbid water, light penetration may only be a few meters.
What wavelength of light penetrates the deepest?
In the ocean, blue light penetrates the deepest due to its shorter wavelength and higher energy compared to longer-wavelength light. Blue light can travel further through water before being absorbed, making it the dominant color at greater depths.
Why is there no red light below 6 meters in the ocean but there is blue light at 35 meters?
Red light is absorbed quickly in water and doesn't penetrate past a few meters, while blue light can penetrate deeper as it is scattered less and absorbed more slowly. That's why red light is not visible below 6 meters in the ocean, while blue light can still be seen at 35 meters.
Why is ocean water blue?
Ocean water appears blue because it absorbs colors in the red part of the light spectrum and reflects blue light. This happens because water molecules absorb longer wavelengths of light, like red and orange, while shorter wavelengths, like blue, are scattered and reflected back to our eyes.
What happens to the wavelengths of light that penetrate into the ocean?
they are absorbed
What is true about the deepest part of the ocean floor?
The deepest parts of oceans are dark all the time because natural light does not penetrate to the ocean depths. Little is known about life in the depths of the ocean. More is known about the moon than the depths of the oceans. Water pressure is great, the temperature is constant.
Why is it impossible for plankton to live in the deepest part of the ocean?
Because they need sunlight, which can't penetrate that deep.
Which color of light penetrates the deepest into the ocean?
blue

What is aphotic zone?
The aphotic zone is the deepest part of the ocean where sunlight cannot reach. It is characterized by complete darkness and is home to various deep-sea organisms that have adapted to survival without light. The aphotic zone starts below the photic zone, which is the upper layer of the ocean where sunlight can penetrate.
Why is it dark in deep ocean?
Because the light cannot penetrate the deepest layer of the ocean called the 'twilight zone,' simply because of depth. If water were perfectly clear and lacked many microorganisms and additional chemicals, perhaps the deeper parts of the ocean would not be dark. However, ocean water is rich with life and nutrients, and therefore has plenty of light-absorbing factors, leading to a zone by which all light has faded away.
To What average depth does light penetrate in the ocean?
There is no "usable" light agter 200 meters...
Is the Atlantic ocean the deepest ocean on earth?
No, the Pacific Ocean has the deepest trenches.
Is the altantic ocean the deepest ocean on earth?
No, Pacific Ocean is the deepest one.
So why is it dark on the seabed if water is transparent?
Light is absorbed and scattered as it passes through water, with longer wavelengths like red light being absorbed first. By the time light reaches the seabed, only blue and green wavelengths are left, resulting in a bluish tint. Additionally, sunlight doesn't penetrate very deep into the ocean, making the seabed appear dark.
