Scientists have long held the belief that the fracturing of the Earth's brittle outer shell into faults along the deep ocean's mountainous landscape occurs only during long periods when no magma has ...

One of the Earth's best-ever baby pictures reveals how crust forms at the biggest volcanic feature on the planet. The detailed look at molten magma beneath a mid-ocean ridge, one of the giant undersea ...

Along submarine mountain ranges, the mid-ocean ridges, forces from the Earth's interior push tectonic plates apart, forming new ocean floor and thus moving continents about. However, many features of ...

Preface / W. Roger Buck...[et al] -- Global systematics of mid-ocean ridge morphology / Christopher Small -- Linkages between faulting, volcanism, hydrothermal activity and segmentation on fast ...

Some of the highest quality images ever taken of the Earth's lower crust reveal that the upper and lower crust form in two distinctly different ways. A team led by researchers from Columbia University ...

The Deep-Ocean Floor The discovery that it is growing outward from the mid-ocean ridges has suggested that it is formed In huge plates that act as units in the dynamic processes of the earth's crust ...

THE theory of ocean floor spreading requires that oceanic crust be generated at mid-ocean ridges. Evidence from a variety of sources suggests that the new crust is made largely of basalt and gabbro, ...
