Which ocean zone has the most sunlight?

Answer 1

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.
