Sunlight sufficient to power photosynthesis in marine plants penetrates to a depth of approximately (~660 feet). Sunlight decreases from this depth to approximately 900 meters (~3000 feet) where sunlight no longer penetrates. This sunlight-less region is known as the aphotic zone.
Sunlight can penetrate into the ocean to an average depth of about 200 meters (656 feet). This depth can vary depending on factors such as water clarity, time of day, and geographic location. Beyond this depth, the ocean becomes progressively darker as less sunlight is able to penetrate.
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.
sound waves can penetrate the ocean floor.
There is no "usable" light agter 200 meters...
The further down, the less sunlight is able to penetrate into the darkness.
No, sunlight does not reach the abyssal plains. The abyssal plains are located in the deep ocean, typically at depths of 3,000 to 6,000 meters, where sunlight cannot penetrate. This lack of sunlight creates a dark and cold environment in this region.
Because they need sunlight, which can't penetrate that deep.
The relationship between depth and sunlight is that sunlight penetration decreases as depth increases in water. This is due to the absorption and scattering of light by water molecules and particles. Consequently, less sunlight reaches deeper parts of the water column, affecting the availability of light for photosynthesis and primary production.
Water molecules absorb and scatter sunlight. Blue light is scattered more than other colors, creating the appearance of a blue ocean. This effect is intensified by the depth of the ocean, which allows blue light to penetrate more than other colors.
the more you go down the denser the water gets until the water is so dense that the sunlight can't reach the bottom of the ocean.
Somewhere in the Mesopelagic Zone (200m to 1000m). Although enough sunlight makes it here for some animals it is too dim for photosynthesis. There is no sunlight beneath this zone.
Oceans consist of 3 Zones, which are classified by the amount of light that passes through. The top two Ocean layers allow for sunlight to penetrate through, however NOT the third & deepest ocean zone. Euphotic Zone or 'Sunlight' Zone - Depth 200 Meters: The top most 200 meters of ocean is called the Euphotic Zone (or called the 'Sunlight' Zone). Sunlight travels easily throughout this Zone of the Ocean and plant-life flourishes in this Zone and is immensely widespread. Dysphotic Zone or 'Twilight' Zone - Depth 200 Meters - 1000 Meters: This layer, immediately beneath the Euphotic Zone/'Sunlight' Zone, between 200 meters and 1000 meters is called the Dysphotic Zone (or more commonly called the 'Twilight' Zone). Sunlight dissipates quickly as the depth increases, and very little light penetrates throughout this zone. Aphotic Zone or 'Midnight' Zone - Depth 1000+ Meters: The Aphotic Zone (sometimes called the 'Midnight' Zone), exists at depths below 1000 meters. No sunlight reaches this zone at all. It is completely absent of light; hence the slang term for it - 'Midnight' Zone.
