How does the earth's core stay molten
WebApr 17, 2024 · The results showed that for the best match, Mercury must have a large, solid inner core. They estimated that the solid, iron core is about 1,260 miles (about 2,000 kilometers) wide and makes up about half of Mercury’s entire core (about 2,440 miles, or nearly 4,000 kilometers, wide). In contrast, Earth’s solid core is about 1,500 miles ... WebIn fact, Earth's outer core is approximately 5 to 10 percent lower density than iron at Earth's core temperatures and pressures. Hence it has been proposed that light elements with …

WebDec 18, 2015 · $\begingroup$ I think Earth's outer core layer is still molten but the inner core is solid (due to pressure, etc). Also the solid part is growing as the molten part around it crystallises. So the question may benefit from editing to make it more clear. (Still a good question in my opinion.) $\endgroup$ WebNov 20, 2008 · Heavy elements like iron and even the heaviest elements at the upper end of the periodic table can become part of a planet's core.

WebSince its formation, the Earth has been losing heat to space. Certain elements, known as radioactive elements such as potassium, uranium, and thorium, break down through a process known as radioactive decay, and release energy. This radioactive decay in Earth’s crust and mantle continuously adds heat and slows the cooling of the Earth.
