Answer

Aphotic Zone or 'Midnight' Zone.

No Sunlight Reaches the Layer of Oceanreferred to as the Aphotic Zone or 'Midnight' Zone- this is at Ocean Depths of 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, the 'Midnight' Zone.

Detailed Explanation

Oceans consist of 3 Zones, the Zones 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 Layer.

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 through this Zone of the Ocean and plant-life is 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, Dysphotic 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.

Difference between photic zone and aphotic zone?

Photic Zone: part of the ocean that receives sunlight Aphotic Zone: area in an ocean where sunlight does not reach and photosynthesis does not occur


Which term describes the upper part of the ocean into which sunlight penetrates?

The term that describes the upper part of the ocean into which sunlight penetrates is called the "euphotic zone." This is where photosynthesis occurs as sunlight is able to reach the surface layers of the ocean, supporting the growth of phytoplankton and other marine plants.


What organisms does require sunlight to live?

Some that live in the bottom of the ocean, where no sunlight can reach it.


Which zone of the ocean does sunlight never reach?

Aphotic zone.

What is the temp of the open ocean zone?

surface/ open ocean zone was warmer than the deep ocean. Sunlight can reach the open ocean so the temp. is warm.


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.

Where is there no sunlight?

Sunlight does not reach the deep ocean depths, underground caves, or areas in polar regions during winter when the sun does not rise for an extended period of time.


What zone does sunlight reach through?

Sunlight can reach through all the zones of the ocean, including the epipelagic (sunlight zone), mesopelagic, bathypelagic, abyssopelagic, and hadalpelagic zones. The intensity of sunlight decreases with depth, so the amount of light available for photosynthesis decreases below the epipelagic zone.
