The heat that is present in Earth's mantle is made up of leftover heat from when the planet was formed, latent heat from the Earth's inner core and heat produced by the decay of radioactive isotopes. The majority of the heat is caused by the decay of isotopes such as potassium 40 and uranium 238.Know More
When an isotope breaks down, it sheds extra energy so that it can become more stable. This extra energy is radiated as heat and warms the mantle.
Earth's core contains liquid metal that expands a little bit every year. This expansion causes heat to spread to the mantle.
The Earth was created when gravity caused particles and hot gases to condense into a planet. Heat was also created by this process, and some of the heat is still around, warming the mantle.Learn more in Layers of the Earth
The state of matter of Earth's inner core is solid. This highly compact sphere is due to the extreme pressures generated within the inner core.Full Answer >
According to National Geographic, the inner core of the Earth ranges between 9,000 and 13,000 degrees Fahrenheit. This is approximately as high as the temperature of the sun's surface.Full Answer >
The Earth consists of four layers: crust, mantle, outer core and inner core. Each layer has its own properties and characteristics that separates it from the other layers.Full Answer >
The temperature of the continental crust varies depending on location and depth; at the surface, the continental crust exists at the same temperature as the outside air, while its inner core reaches temperatures up to 1600 degrees Fahrenheit. The continental crust consists of many levels, and exists on land and underneath the ocean. The top layer of the crust below the ocean floor typically experiences cooler temperatures than the crust forming the ground on land masses, but both have hot inner cores.Full Answer >
