Sea Floor Spreading Animation

Enumerate and explain the evidences that support the sea floor spreading process.

Sea floor spreading animation. The discovery of this phenomenon was an important bit of evidence that helped confirm the theory of plate tectonics. Seafloor spreading and other tectonic activity processes are the result of mantle convection. Topic objectives for groupreporters c. Maps and other data gathered during the war allowed scientists to develop the seafloor spreading hypothesis this hypothesis traces oceanic crust from its origin at a mid ocean ridge to its destruction at a deep sea trench and is the mechanism for continental drift.
