C. Central Atlantic Ocean floor
The Central Atlantic Ocean floor is a vast underwater region characterized by mid-ocean ridges, fracture zones, and sediment-covered abyssal plains formed by seafloor spreading between the Americas and Africa-Europe.
D. Tropical Northwestern Atlantic
The Tropical Northwestern Atlantic is a marine ecoregion characterized by warm, clear tropical waters, coral reefs, and diverse marine life in the western Atlantic Ocean, including areas around the Lucayan Archipelago.
E. North Atlantic area
The North Atlantic area is the broad transatlantic region encompassing the northern parts of the Atlantic Ocean and surrounding countries in Europe and North America that form the geographic focus of NATO’s collective security.
