Why is the ocean so deep?
The ocean has an average depth of approximately 3.7 kilometres (or 2.3 miles). … The extreme depth of the Mariana Trench and other oceanic trenches is caused by subduction – where on the boundary of two converging tectonic plates one descends down into Earth’s mantle creating a deep trough.

How cold is the bottom of ocean?
Therefore the deep ocean (below about 200 meters depth) is cold with an average temperature of only 4°C (39°F). Cold water is also more dense and as a result heavier than warm water. Colder water sinks below the warm water at the surface which contributes to the coldness of the deep ocean.
