Temperature within Earth increases with depth. Highly viscous or partially molten rock at temperatures between 650 to 1,200 °C (1,200 to 2,200 °F) are found at the margins of tectonic plates, increasing the geothermal gradient in the vicinity, but only the outer core is postulated to exist in a molten or fluid state, and the temperature at Earth's inner core/outer core boundary, around 3,… Webb1 juni 2024 · The outer core extends for around 1,400 miles and mostly consists of liquid iron and nickel. Temperatures here are thought to range between around 7,200 and …

Webb7 mars 2024 · 4. The outer core’s NiFe alloy is extremely heated. The temperature of the outer core is estimated to be around 3,000-4,500 K (2,700-4,200 °C; 4,900-7,600 °F) in its outer area. The temperature then nearly doubles at the boundary between the outer and inner cores, to about 4,000-8,000 K (3,700-7,700 °C; 6,700-14,000 °F). WebbAnd the high-temperature gas from the inlet into the calcination zone after 2 m distance, the temperature drops sharply, especially from the chamber wall 0.08 m and 0.12 m gas drop more. While the calcining area is centered and closer to the chamber wall, the temperature drop is relatively gentle. photo essay about school
