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.

Which of the following statements accurately describe the characteristics of lake ecosystems?

Lake ecosystems, unlike lotic ecosystems, are characterized by static water bodies.
Light penetration in lakes is consistently uniform throughout the water column.
Dissolved oxygen levels in lakes are typically higher than in lotic systems due to greater surface area contact with air.
Vertical zonation in lakes is primarily influenced by variations in temperature, sunlight, and dissolved oxygen.
