These age data also allow the rate of seafloor spreading to be determined and they show that rates.

Complete the cycle diagram of sea floor spreading.

When the concept of seafloor spreading came along scientists recognized that it was the mechanism to explain how continents could move around earth s surface. Include as much detail as you can. This idea played a pivotal role in the development of the theory of plate tectonics which revolutionized geologic thought during the last quarter of the 20th century. Like the scientists before us we will now merge the ideas of continental drift and seafloor spreading into the theory of plate tectonics.

Draw a diagram of seafloor spreading. As upwelling of magma continues the plates continue to diverge a process known as seafloor spreading samples collected from the ocean floor show that the age of oceanic crust increases with distance from the spreading centre important evidence in favour of this process.
