The mantle has no huge source of heat of itself. The mantle is in continuous convection, and is also conducting heat from the outer core and in turn from the inner core.
In the core materials, themselves mainly nickel and iron, are also many of the heavy radioactive elements. The radioactive decay of these is the ultimate source of the heat of the Earth's Core. It is believed to have a temperature about the same as the surface of the Sun, over 5000 deg C.

What elements heat the inside of Earth?
The heat inside Earth primarily comes from two sources: residual heat from its formation, and the decay of radioactive elements in the mantle and core. This heat drives the movement of material in the Earth's interior, creating processes like mantle convection and the generation of Earth's magnetic field.
How many layers in earths mantle?
The Earth's mantle has two main layers: the upper mantle and the lower mantle. These layers are distinguished by differences in their composition, temperature, and behavior. The upper mantle extends from the crust to a depth of about 410 miles (660 kilometers), while the lower mantle extends from about 410 miles (660 kilometers) to approximately 1,800 miles (2,900 kilometers) below the Earth's surface.
What are facts about earths upper mantle?
Temperature is about 2000 to 3000 degrees celsius maybe less.The mantle is hot but not the hottest layer.It is is the second layer of the Earth. The mantle is the thickest layer of the earth, it is the layer of the earth beneath the crust.Upper mantle and Lower mantle are the two parts of the mantle, The lower mantle is deeper and denser than the upper mantle .
Where does the convection currents in Earth's mantle obtain its heat energy?
Convection currents in Earth's mantle obtain their heat energy primarily from two sources: the residual heat from the planet's formation and the decay of radioactive isotopes, such as uranium, thorium, and potassium. This heat causes the mantle material to become less dense and rise, while cooler, denser material sinks, creating a continuous cycle. Additionally, some heat is generated from the core due to its solidification and the motion of liquid iron. These processes drive the convection currents that influence tectonic activity.
What are two divisiosn of the earths core?
, a liquid outer core that is much less viscous than the mantle, and a solid inner core.
What is the main source of the earths interior heat?
the mantle plume There are two source of heat in the earth's interior. The main two sources are fire and breathing heat.
What are the two sources of earths internal heat energy?
The two main sources of Earth's internal heat energy are residual heat from the planet's formation over 4.6 billion years ago and the decay of radioactive isotopes within the Earth's mantle. The heat generated by these processes contributes to the movement of tectonic plates and drives geological activity on the planet.
What is the main source of heat in Earth's interior?
the mantle plume There are two source of heat in the earth's interior. The main two sources are fire and breathing heat.
What are two sources of thermal energy in Earths interior?
Two sources of thermal energy in Earth's interior are residual heat from the planet's formation over 4.5 billion years ago and radioactive decay of elements like uranium, thorium, and potassium within the Earth's crust and mantle.
Two types of heat in are earth?
The two main sources of heat within Earth are primordial heat left over from the planet's formation over 4.5 billion years ago, and radiogenic heat produced by the decay of radioactive isotopes in the mantle and crust. These heat sources drive geological processes such as mantle convection and plate tectonics.
What are two main sources of heating in the earth?
The two main sources of heating in the Earth are radioactive decay of elements like uranium, thorium, and potassium in the mantle, and residual heat from the Earth's formation over 4.5 billion years ago. These heat sources contribute to the movement of tectonic plates and drive processes like mantle convection and volcanic activity.
How is heat from earths interior transferred to earths surface by convections?
Beneath the surface of the earth temperature remains the same. Within the Earth, irregular convection cells within the mantle transfer heat from the core to the surface of the planet. Volcanoes and earthquakes are two examples of heat transferring from the interior to the surface.
What elements heat the inside of Earth?
The heat inside Earth primarily comes from two sources: residual heat from its formation, and the decay of radioactive elements in the mantle and core. This heat drives the movement of material in the Earth's interior, creating processes like mantle convection and the generation of Earth's magnetic field.
What is the source of the energy that powers the earths system?
The Earth system is powered by energy from two major sources: the Sun and the planet's internal heat.
What are two sources of the Earths energy?
the sun and the moon
What is the thicness for the earths crust?

Is the sun the heat source for the convection currents in the mantle?
The heat in the Earth's interior comes from two main sources: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust and the primordial heat left over from the formation of the Earth.
