Spreading centers occur mainly along mid-ocean ridges, where two oceanic plates are pulling apart from each other. As they move apart, magma rises from beneath the Earth’s crust to fill the gap, creating new oceanic crust. The Mid-Atlantic Ridge is a prime example of a spreading center. ...
The collision of tectonic plates produces enough heat to deform continent. For instance, an outcropping on the Cornwall coast in southwestern England shows evidence of having been folded by the heat and pressure associa...
The east side of the North American Plate straddles theEurasian PlateandAfrican Plate. This is the Mid-Atlantic Ridge wheredivergent tectonic platespull apart from each other. In turn, we find some of the youngest geologic rocks at these mid-oceanic ridges. FARALLON PLATE:The Farallon Plate was...
The question has long puzzled scientists because conventional wisdom said that sinking tectonic plates must remain intact to keep pulling on the portion behind it, but according to geophysical evidence, they are destroyed. Now, in a study published recently inNature, scientists say they’ve ...
According to Geologists, billions of years ago, the landmasses were all bunched together as one massive supercontinent. This supercontinent then broke apart due to constant pushing and pulling and formed continents, oceans, and other landforms. This is known asPlate tectonics. ...

Fig. 3: pulling apart of the continent—the splitting of the continental block leads to the formation of oceans and islands (above A), whilst at B, the enriched Sial forms a rising border zone in front of a foredeep-trench with the formation of a geosyncline behind. Fig. 4: another ...
The article discusses the cycles of amalgamation and dispersal of landmasses that have affected the Earth's crust and underlying mantle, its atmosphere and climate, and the life it supports. The landmass collision that closed the Rheic Ocean was the culmination of a long period of mountain ...
oblique to spreading direction causes enhanced melting beneath the leading segment end (Katz et al., 2004), we attempt to understand the formation of faults when the near-field spreading direction is oblique to the far-field stretching direction (i.e., the direction plates are pulled apart). ...
