Web30 Jul 2024 · The thickness of the seafloor lithosphere is rather constant, although near the mid-ocean ridges, mantle temperature is higher than average because of the upward migration of hotter mantle rock ... Web18 May 2024 · Below the lithosphere, the temperature is believed to reach 1,832°F (1,000°C) which is warm enough to allow rock material to flow if pressurized. Seismic evidence suggests that there is also some molten material at this depth (perhaps about 10%).
