seafloor spreading | National Geographic Society Seafloor spreading occurs along mid ocean ridges—large mountain ranges rising from the ocean floor. The Mid Atlantic Ridge, for instance, separates the North American plate from the Eurasian plate, and the South American plate from the African plate.The East Pacific Rise is a mid ocean ridge that runs through the eastern Pacific Ocean and separates the Pacific plate from the North American ... Seafloor Spreading Windows to the Universe Seafloor Spreading This diagram provides evidence of seafloor spreading by showing the ages of ocean floor in the Atlantic and eastern Pacific Oceans. The red colors are the youngest parts of the seafloor, where fresh new crust is formed as lava seeps up from the deep interior of the Earth at spreading ridges.

If we drill a series of holes in the ocean floor that are progressively further away from an ocean ridge, we MODEL OF SEA FLOOR SPREADING ucmp.berkeley.edu This is the case. The oldest known ocean floor is dated at about 200 million years, indicating that older ocean floor has been destroyed through subduction at deep sea trenches. It took exploration of the ocean floor to discover sea floor spreading, the mechanism for the movement of continents that Alfred Wegener lacked.

Seafloor spreading Spreading rate is the rate at which an ocean basin widens due to seafloor spreading. (The rate at which new oceanic lithosphere is added to each tectonic plate on either side of a mid ocean ridge is the spreading half rate and is equal to half of the spreading rate). Spreading rates determine if the ridge is fast, intermediate, or slow. Transform fault A transform fault or transform boundary is a plate boundary where the motion is predominantly horizontal. It ends abruptly and is connected to another transform, a spreading ridge, or a subduction zone.. Most of these faults are hidden in the deep ocean, where they offset divergent boundaries in short zigzags resulting from seafloor spreading, the best known (and most destructive) being those ... Seafloor Spreading Activity NOAA Ocean Explorer Seafloor Spreading Activity. ... Such magnetic patterns led to recognition of the occurrence of sea floor spreading, and they remain some of the strongest evidence for the theory of plate tectonics. The figure below includes two images of the ocean floor. The map view depicts the visible appearance of the oceanic crust. seafloor spreading (lesson 0077) TQA explorer Seafloor spreading is the mechanism that Wegener was looking for! instructional diagrams. This image shows the sea floor spreading. Seafloor spreading is a process that occurs at mid ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.
