Sea Floor

These undersea ridges work like elongated fountains on the slow timescale of geology, welling up molten rock in the process I have already mentioned called sea-floor spreading. ❋ RICHARD DAWKINS (2009)

Think of a plate, instead, as being continuously manufactured at a growing edge, in a remarkable process called sea-floor spreading, which I shall explain in a moment. ❋ RICHARD DAWKINS (2009)

"Accessing the treasure trove of key elements on the ocean floor will be very expensive and potentially harmful to sea-floor ecology," Nature Geoscience said in a related article. ❋ Denny Kurien (2011)

This is sea-floor spreading prior to becoming, like, you know, and actual sea floor. ❋ M_francis (2009)

BP said in a news release that during the course of sea-floor inspection, "small intermittent bubbles were observed emanating from cement ports at the base of the wellheads." ❋ Ryan Dezember (2011)

"It all adds up to: It's not gone," said David Hollander, a professor at the University of South Florida, who worked on the sea-floor study. ❋ Unknown (2010)

Early research on how to avoid hydrate buildup eventually led to the discovery of naturally occurring methane hydrates in the '70s, which are found pretty much everywhere temperature and pressure conditions permit — in the sea-floor sediments of all oceans deeper than about 2,000 feet and in permafrost. ❋ Unknown (2010)

The blowout preventer on the Deepwater Horizon, the safety device of last-resort, was on the sea-floor, a mile below the surface, a common practice on exploratory wells. ❋ Unknown (2010)

Potentially just as important: revenues from magnesium and other sea-floor minerals that geologists have been exploring in recent years. ❋ Travis Walter Donovan (2010)

Video gives first look at oil gushing from sea-floor well ❋ Unknown (2010)

An environmental lawsuit is threatening the departure of a long-planned, US$4.7-million research cruise to image sea-floor structures off the coast of western Canada. ❋ Unknown (2009)

The combination of sea-floor spreading and subduction means that there are no gaps between plates. ❋ RICHARD DAWKINS (2009)

The entire surface of the planet is covered in plates, each one typically disappearing by subduction underneath a neighbouring plate on one side, or sliding past another plate, while it grows out from a sea-floor spreading zone elsewhere. ❋ RICHARD DAWKINS (2009)

The spreading sea-floor ridge in mid-Atlantic seems to push the African plate eastwards and the South American plate westwards. ❋ RICHARD DAWKINS (2009)
