Sunglight entering the water may travel about 1,000 meters (3,280 feet) into the ocean under the right conditions, but there is rarely any any significant light beyond 200 meters (656 feet).
Light may be detected as far as 1,000 meters down in the ocean, but there is rarely any significant light beyond 200 meters.
Sunlight entering the water may travel about 1,000 meters (3,280 feet) into the ocean under the right conditions, but there is rarely any significant light beyond 200 meters (656 feet).
The ocean is divided into three zones based on depth and light level. The upper 200 meters (656 feet) of the ocean is called the euphotic, or "sunlight," zone. This zone contains the vast majority of commercial fisheries and is home to many protected marine mammals and sea turtles.
Only a small amount of light penetrates beyond this depth.
The zone between 200 meters (656 feet) and 1,000 meters (3,280 feet) is usually referred to as the “twilight” zone, but is officially the dysphotic zone. In this zone, the intensity of light rapidly dissipates as depth increases. Such a minuscule amount of light penetrates beyond a depth of 200 meters that photosynthesis is no longer possible.
The aphotic, or “midnight,” zone exists in depths below 1,000 meters (3,280 feet). Sunlight does not penetrate to these depths and the zone is bathed in darkness.
‘Photic’ is a derivative of ‘photon,’ the word for a particle of light.

How could energy have played a role in the different rock types forming? Energy causes different types of rock to change in different ways. Energy changes igneous rock into liquid rock and changes sedimentary rock into small pieces of rock. ... No, sedimentary rock can only form out of material from other sedimentary rock.D
Pharmacists may be more familiar and comfortable with the concept of quantitative rather than qualitative research. Quantitative research can be defined as “the means for testing objective theories by examining the relationship among variables which in turn can be measured so that numbered data can be analyzed using statistical procedures”.1 Pharmacists may have used such methods to carry out audits or surveys within their own practice settings; if so, they may have had a sense of “something missing” from their data
19. The atomic number indicates how many neutrons there are, and the atomic mass tells us how many protons and neutrons are present within the nucleus of an atom.
