The Indian Ocean is home to a mountain range longer than the North American Rockies, and yet today, all 5,000 kilometers ...

Telltale hot spot tracks form as tectonic plates move over these plumes ... suppressing mantle melting, halting the creation ...

New Curtin University research has revealed that the Ninetyeast Ridge ­— the Earth’s longest straight underwater mountain ...

Dynamic Earth clearly details the mechanisms responsible for plate tectonics, volcanic hotspots, and many resulting geological processes ... Geoffrey Davies has changed all that with his superb book, ...

Geography textbooks describe the Earth's mantle ... today's volcanoes. But that presented the team with yet another conundrum. Volcanoes like those on Easter Island are so-called "hotspot volcanoes." ...

Mantle convection is the process underlying plate tectonics, volcanic hotspots and, hence, most geological processes ... As a general rattle of plates and a dance of plumes, the book has much to be ...

Seamounts are underwater volcanoes found in every single ocean. They are caused by 'hotspots' beneath Earth's surface, in which gathering heat melts away the mantle, releasing hot plumes in a pipe ...

Key fact The 'hotspot' theory is that there are fixed spots in the mantle where magma rises to the surface. As the crust is moved over these fixed spots, volcanoes are created, eventually forming ...

How hotspots develop. Credit: Volcano Museum Starting in October ... the large volcanoes in the interior also appear to be over a mantle plume, similar to Hawaii. This kind of volcano typically ...

The Cumbre Vieja volcano on La Palma erupted ... rather than along a plate boundary. Hot spots occur where columns of superheated magma, or mantle plumes, cause the Earth's crust to melt and ...
