Why is the Strait of Gibraltar so much deeper than the area surrounding it?

I couldn’t find a reliable answer online and I am not sure if this counts as science, but I’m curious to why the Strait of Gibraltar is so deep in such a specific spot in the world.

The Zanclean flood. The African plate and Eurasian plate are moving towards each other, as they have been for millions of years. They ran into each other and closed the connection between the Atlantic ocean and the  Mediterranean Sea. The latter became the dried out and became the Mediterranean basin. 5.33 million years ago the connection reopened and water came rushing back in to fill the Mediterranean. The tremendous volume of water squeezed through a narrow channel, the water moving quickest at the narrowest point.  The fast flowing water carried material and carved the channel we see today. The channel will close again as the plates continue to collide.
