Or old english sund.

Does the ocean floor old the farther away it is. The ocean floor may be more exciting to explore than any mountain above sea level. So how do we make maps of the global ocean floor. As plates converge one plate may move under the other causing earthquakes forming volcanoes or creating deep ocean trenches. The surface manifestation of a mantle plume is a hot spot.

It didn t provide dates or chemical analyses of the ocean floor but it did uncover long oceanic ridges steep canyons and many other landforms that are indicators of plate tectonics. The shifting plates may collide converge move away diverge or slide past transform each other. Visualize how the atlantic ocean floor started separating the continents and grew to its present size. About three quarters of our planet s surface is covered with water and the deep basins of the ocean floor account for approximately nine tenths of this water covered area that is some two thirds of the earth s surface.

It turns out that satellites can. Earlier theories by alfred wegener and alexander du toit of continental drift postulated that continents in motion plowed through the fixed and immovable seafloor. The idea that the seafloor itself moves and also carries the continents with it as it spreads from a central rift axis was proposed by harold hammond hess from princeton university and robert dietz of the u s. A mantle plume is a mass of hotter than normal mantle material that ascends toward the surface.

They found that the ocean floor gets older the farther away from the mid ocean ridges. Based on ages of the oldest rocks in the north and south atlantic describe how and when the atlantic ocean formed and how its shape has changed through time. Read this lesson to learn about what you ll see on the ocean. I don t like the ocean i would drown and my ears react in water.
