They are not bottomless, just very deep. These cracks are called deep sea trenches. They are also not located in the ocean "basins" - they are on the edges, along tectonic plate boundaries.

Trenches have nothing to do with bottomless cracks, they are just deep "valleys" in the ocean floor.
ocean basic? do you mean basin? Then they the meeting point for 2 major Plates. The two plates that meet in the middle of the Atlantic Ocean are drifting apart forming a crack, out of which flows magma. So in the distance future, there will be a mountain range in the middle of a much wider Atlantic Ocean.

It's not bottomless. The deepest part of the ocean is quite a few miles deep, though I'm having a hard time remembering how deep exactly. Edit: Found it, the deepest part of the ocean is the Mariana Trench, at over 6.7 miles deep. Why is a geology question in R&S?

there are trenches which are generally large deep ravines in the oceans floor that have a bottom these have not all been explored all the way to the bottom but they do have a bottom.
Then there are vents. These are cracks that release different gasses and create eco systems at the bottom of the ocean. I am unsure of which one you are asking for so here are both.
