| Under normal conditions, coral growth can easily keep up with sinking due to seafloor spreading. |
|
| The following year, geophysicist Robert S. Dietz named the phenomenon seafloor spreading. |
|
| This all-encompassing theory grew out of observations and ideas about continental drift and seafloor spreading. |
|
| Magma invades the cracks, and the process of continental rifting, ultimately leading to seafloor spreading, begins. |
|
| A high heat flow, which is associated with the extrusion of magma and with seafloor spreading, exists in the rift zone. |
|
| Tectonic and structural features Elements of global-scale crustal dynamics including continental drift and seafloor spreading. |
|
| East-northeast seafloor spreading in Labrador Sea began in Late Cretaceous time but changed to north-northeast in the Early Eocene. |
|
| It is clear from aeromagnetic and seismic data that the Eurasia Basin was formed by seafloor spreading along the axis of the Nansen-Gakkel Ridge. |
|
| As rifting proceeds, seafloor spreading occurs and an up-welling melt creates the oceanic crust. |
|
| At least five different seafloor spreading centres were involved. |
|
| Unwarranted assumptions about uniform rates of sedimenation or seafloor spreading, or uniform durations of fossil zones were avoided wherever possible. |
|
| On the other hand, seafloor spreading continued during the Cretaceous and Cenozoic in the North Atlantic where the Mid-Atlantic Ridge remains an active spreading centre today. |
|
| This simplifies the plate reconstructions and makes it easier to determine the position of the Fylla structure adjacent to the Baffin and Labrador margins prior to seafloor spreading. |
|
| A profound consequence of seafloor spreading is that new crust was, and still is, being continually created along the oceanic ridges. |
|
| The process that continually adds new material to the ocean floor is seafloor spreading and the continental slope. |
|
| Two of these evolve to the point of seafloor spreading, while the third ultimately fails, becoming an aulacogen. |
|
| Some scientists interpreted these as requiring plate tectonic processes, such as seafloor spreading. |
|
| In the 1960s, geologists discovered and began to propose mechanisms for seafloor spreading. |
|
| Since then, it has been shown that the motion of the continents is linked to seafloor spreading. |
|
| The driver for seafloor spreading in plates with active margins is the weight of the cool, dense, subducting slabs that pull them along. |
|
|
|
| As the seafloor spreading axis moves along the margin, thermal uplift produces a ridge. |
|
| The process of seafloor spreading helps to explain the concept of continental drift in the theory of plate tectonics. |
|
| Accretion occurs as mantle is added to the growing edges of a tectonic plate, usually associated with seafloor spreading. |
|
| This is followed by passive margin environments, while seafloor spreading continues and the oceans grow. |
|
| The exploration of the MAR in the 1950s led to the general acceptance of seafloor spreading and plate tectonics. |
|
| Through the process of seafloor spreading, new ocean crust continually comes into being here. |
|
| The exploration of the MAR in the 1950s lead to the general acceptance of seafloor spreading and plate tectonics. |
|
| Those igneous rocks formed in the faulted and thinned continental margin of northwestern Europe contemporaneously with the rifting and seafloor spreading that gave rise to the Atlantic Ocean. |
|
| Molten rock erupts onto the seafloor there, then cools and rifts away from the ridge on either side in a process known as seafloor spreading. |
|
| Changes in seafloor spreading rates and glaciations have caused sea levels to rise and fall, greatly altering the deep-sea sedimentation pattern of both terrigenous and biogenic sediments. |
|
| A veritable legion of evidence supports the seafloor spreading hypothesis. |
|
| What's more, they gathered evidence that seafloor spreading on the Gakkel Ridge occurs in a fundamentally different way compared to other previously explored ridges. |
|
| This type of oceanic mountain ridge is characteristic of what is known as an oceanic spreading center, which is responsible for seafloor spreading. |
|
| As the seafloor spreads, magma wells up from the mantle, cools to form new basaltic crust on both sides of the ridge, and is carried away from it by seafloor spreading. |
|
| Coast and Geodetic Survey who first coined the term seafloor spreading. |
|
| This theory is supported by several types of observations, including seafloor spreading and the global distribution of mountain terrain and seismicity. |
|
| Rifting and subsequent seafloor spreading progressed from south to north. |
|
| Because parts of the ridge are continually spreading and forming new sections of seafloor, scientists call these places seafloor spreading centers. |
|
| Seafloor spreading helps explain continental drift in the theory of plate tectonics. |
