Answer:

The continental slope after some distance forming the continental rise which may be geologically active.
Continental rise has canyons and trenches which are subject to underwater eruptions and avalanches. The region of the continental slope and rise together comprise the bathyal zone.
The bathyal zone which is 200 metres deep descends rapidly to a depth of 3,000 or 4,000 m.
From this the bottom drops for further several thousand metres and levels, off around 6,000 m to form the broad flat abyssal plains where temperature is never above 4°C.
