No, it is the steep transitional zone. The deepest parts are in the abyssal plains or ocean trenches, which are beyond the slope.
No, it is entirely submerged, typically starting at depths of around 130-200 metres and extending to about 3000-4000 metres.
It is ecologically rich, hosts unique habitats like cold-water coral reefs, and is geologically active with landslides and sediment transport crucial for forming deep-sea deposits.
A continental slope is a standard feature of all continental margins. An oceanic trench is a much deeper, narrow cleft formed by tectonic plate subduction, often found near slopes but distinct from them.
The steep, sloping section of the seabed that connects the continental shelf to the deep ocean floor (abyssal plain).
