A volcanic archipelago in the Pacific Ocean
Mendocino, Molokai, and Galapagos are names of fracture zones in the ocean floor, where tectonic plates are moving away from each other. These fracture zones are characterized by a series of faults and ridges that form due to the movement of the Earth's tectonic plates. They play a significant role in shaping the geology and topography of the ocean floor.
Galapagos is IN the South Pacific Ocean.
The Galapagos Islands are in the Pacific Ocean.
A fracture zone is a group of "cracks" in the ocean floor that cut across a rift. For example, if you look at a picture of the Mid-Atlantic Ridge, you'll see that there are hundreds of smaller fractures in the earth's crust that cut across the ridge. There's a great picture of the Mid-Atlantic Fracture Zone at the link below.
Ocean and seas
The Galapagos is located west of Ecuador (I think) and is near the equator. To make an answer short (Too late!) it is in the Pacific Ocean.
The Galapagos is an archipelago, which means it is a group of islands located in the Pacific Ocean, off the coast of Ecuador.
The Galapagos Islands are a province of Ecuador.
The Galapagos Islands were merely bordered by the Pacific Ocean in the west.
The Galapagos are an archipelago of volcanic islands distributed on either side of the Equator in the Pacific Ocean.
The epipelagic ocean zone is most habitable.
The ocean floor is the most anaerobic zone in the ocean.
