Why are there fewer islands in the Atlantic?

Factual Questions

The Pacific is just loaded wth them, right? More islands than you possibly name, but I can’t really name more than a few islands and groups in the Atlantic Ocean (Canaries, Azores off the top of my head.) I’m not talking about islands just off the coast of continents, either, but out in the middle of the ocean. I’m pretty sure it’s not a matter of the Pacific being bigger than the Atlantic, either.

So what is it? More volcanic action in the Pacific?

I think the lack of volcanic activity is only half of it. True, most (if not all) Pacific islands are volcanic in origin, so a lack of volcanic ‘island forming’ activity means a lack of islands. But…

The Atlantic Ocean is growing. That is, Europe and Africa are getting farther away from North and South America due to continential drift. So where the Pacific floor has “hot spots”, where magma comes to the surface in a column, forming an island, the Atlantic floor is spreading apart. In the middle (of the Atlantic) is a “Divergent Boundry”. This is an area where magma is rising to the surface and spreading to either side, pushing the continental plates apart.

The Atlantic Ocean is growing. That is, Europe and Africa are getting farther away from North and South America due to continential drift. So where the Pacific floor has “hot spots”, where magma comes to the surface in a column, forming an island, the Atlantic floor is opening, spreading and forming new sea floor.

So, not only is there a different kind of volcanology going on, any islands that did form, would have had to form eons ago, closer to the shoreline.

Those islands which do exist in the Atlantic - Iceland, the Canaries, Bermuda etc…are extinct volcanoes resulting from the spread of the ocean. I guess the answer to the original post is “because the Atlantic needs time to catch up”?
