PPT The Theory of Seafloor Spreading PowerPoint Presentation ID5783402
A multidisciplinary research team from six institutions has for the first time successfully. Web the molten rock cools to form the crust. Web seafloor spreading is the continuous process of forming new igneous rock at midocean ridges by injection of magma that forms new seafloor. Lava rises upward, erupts, and cools. Lava flows from fissures on the. Sometimes lava erupts and flows from long cracks in the earths crust called fissures. As the seafloor spread apart at magma is forced upward and flows from new seafloor. Later, more lava erupts and pushes the original seafloor outward. There are divergent boundaries where the plates are moving away from each other, causing magma to rise up. The boiling lava is almost.
Later, more lava erupts and pushes the original seafloor outward. The new crust is pulled slowly out and away from the ridge as the two plates move apart, making room for molten mantle. Web seafloor definition, the solid surface underlying a sea or an ocean. When oceanic plates diverge, tensional stress causes fractures to occur in the. Lava rises upward, erupts, and cools. Web seafloor spreading is the continuous process of forming new igneous rock at midocean ridges by injection of magma that forms new seafloor. As tectonic plates separate, the sea floor. Lava flows from fissures on the. When the lava cools, the magnetite crystals take on the current magnetic polarity and as more lava erupts, it. How to use seafloor in a sentence. Web the meaning of seafloor is the floor of a sea or ocean :
