What type of rock is most likely dominant at mid ocean ridges? basalt What is crest of Mid Oceanic Ridge? A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics. This feature is where seafloor spreading takes place along a divergent plate boundary. The rate of seafloor spreading determines the morphology of […]
Is the mantle liquid?
Is the mantle liquid? The inner core is solid, the outer core is liquid, and the mantle is solid/plastic. This is due to the relative melting points of the different layers (nickel–iron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases. Can we drill into the mantle? Drilling To […]
