Question about geography/geology
I've been watching some documentaries about the ocean floor, and volcanoes, and stuff like that, and I want to see if I have this right.

So the mid-Atlantic ridge is where new ocean floor is being made. So it is pushing North America and Africa apart.

The place in the Pacific where the plates meet is where the extra ocean floor is disappearing, as one plate slips beneath the other.

Now, the Galapagos Islands are just off the coast of Ecuador, and they are currently sitting over a "hot spot" or a place where volcanoes are born. (I didn't know this, about how pieces of the earth's crust move past these hot spots - I never understood why a volcano would go extinct, like what, it just went out? No, it moves to a cooler neighborhood).

So, does that mean that eventually Ecuador will sit right on that hot spot?

Just rethinking a real estate investment, that's all.

But seriously, is this what is going to happen?

1. Probably, yes.
Or, to be more precisely scientific, one could say "The land mass which is currently labeled Ecuador, will one day be over a volcano in what was heretofore referred to as the 'Volcanic Rim' of the Pacific Ocean"

2. Basically, yes.
You know s'mores, those things that we currently make by putting marshmallows over the fire, then toasting them and putting them between graham crackers and pieces of chocolate? Those will eventually be referred to as "s'mecuadors."

3. Ecuador already has plenty of volcanoes - the subduction of the
Nazca plate under the South American plate makes that a pretty active region for volcanoes, earthquakes, and uplift. But if the continent moves over a hot spot, and the hot spot is still active when the continent gets there, then it would add to the vulcanism...
