Detailed explanation-1: -The abyssal zone has temperatures around 2 to 3 °C (36 to 37 °F) through the large majority of its mass. Due to there being no light, there are no plants producing oxygen, which instead primarily comes from ice that had melted long ago from the polar regions.
Detailed explanation-2: -Because of its high density, the brine sinks and slowly flows along the bottom toward the Equator. Abyssal salinities range narrowly between 34.6 and 35.0 parts per thousand, and temperatures are mostly between 0° and 4° C (32° and 39° F).
Detailed explanation-3: -Away from land, the open sea divides into two main regions, the continental shelves (pale blue on the globe), where water is less than 200m deep, and the deep abyssal plains (dark blue) of the ocean floor, anything from 2, 000m to 6, 000m deep. Between the two is the continental slope.
Detailed explanation-4: -Abyssal salinities range between 34.6 and 35.0 parts per thousand, while the temperature ranges mostly between 0° and 4° C (that is approximately 32° and 39° F).
