Crust submerges into the mantle

WebAnswer (1 of 2): The oceanic crust is young (a few million years) near to the Mid-Ocean Ridge, and much older (100–200 million years) far from the ridge. This is because volcanoes erupt basalt (new oceanic crust) along the ridge, and then it drifts away from the ridge (sea-floor spreading) as mor...

WebOccurs at constructive plate boundaries. Upwelling convection in the mantle causes the crust to form a ridge. Tension develops causing the lithosphere to stretch and crack. The central block moves downwards and magma rises through the faults and forms new crust. This process repeats as convection currents continue. Can form mountain ranges. WebMar 1, 2024 · The mantle is the mostly solid bulk of Earth’s interior. The mantle lies between Earth’s dense, superheated core and its thin outer layer, the crust.

When that weight is removed by erosion over tens of millions of years, the crust rebounds and the mantle rock flows back (Figure 3.2.3, right). olivia newton john cause death

WebMantle convection is the main way heat from Earth’s interior is transported to its surface, and this heat escapes principally through mid-ocean ridges. In fact, the connected mid-ocean ridge system is in essence a 80,000 km long volcano. Escaping heat along these ridges causes hot water to circulate through the crust in a “hydrothermal ...
