Underwater mountain ranges that rise miles from the deep seafloor. That means the rock in the center is the youngest.

Shortly After The Conclusion Of.

It happens on both sides of. Wherever the sea floor is spreading, the edges move apart while the magma in the middle hardens. Sea floor spreading is the process by which continental drift occurs.

Seafloor Spreading And Other Tectonic Activity Processes Are The Result Of Mantle Convection.

The question expects us to explain what sea floor spreading is, the evidences that led to the acceptance of this theory by hess and how the movement of seafloor leads to earthquakes and volcanoes. Its major tenets gave great support to the theory of continental drift and provided a conceptual base for the development of plate tectonics. Undersea mountain ranges are the mountain ranges that are mostly or.

It Also Explained Why The Sediments In The Cores Of Oceanic Ridges Are So Thin.

Here are some of the major features of seafloors: The theory of plate tectonics states that the outer shell of the earth is divided into the different. Seafloor spreading is a part of the theory of plate tectonics.

Seafloor Spreading Solved Many Of The Unsolved Problems.

It also explained why the sediments at the. Depressions usually several miles deep located on the edges of. As the continents move apart, whole new oceans.

As Two Tectonic Plates Slowly Separate, Molten Material Rises Up From Within The Mantle To Fill The Opening.

Underwater mountain ranges that rise miles from the deep seafloor. The constant eruption by volcanoes at the crest of oceanic ridges causes cracks or ruptures of the oceanic crust. Convection currents carry heat from the lower.
