What is the main source of heat in the earth's core?
The heat in the inner core is the result of several different sources. Some of these are: residual heat from the creation of the planet; heat caused by nuclear decay; friction; magnetic and tidal effects.
Can a planetary core be cold?
Certainly, a planetary core can be cold. The heat of our own planetary core is the result of radioactive decay of various elements in the core and mantle, but eventually that heat source will be used up, and the residual heat will gradually leak away into space. There could be other planets which never had much or any abundance radioactive content in the first place.
What causes heat in the inner core?
The heat comes in the part were the core was and it melts
What do geologists believe heats thee upper mantle portion of the asthenosphere?
Geologists believe that the upper mantle portion of the asthenosphere is primarily heated by the residual heat left over from the formation of the Earth, known as radiogenic heat. This heat is generated by the decay of radioactive isotopes present in the mantle. Other sources of heat include the heat transferred from the core and the heat produced by ongoing mantle convection.
What are two sources that heat the earths mantle?
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.
Why the inner core is hot?
From incredible pressures, residual accretion heat, and nuclear reactions. == ==

Where does the Earth's core gets its energy from?
The heat of Earth's core comes from a combination of residual heat of Earth's formation, the decay of radioactive isotopes, and possible fission of uranium at the planet's center.

Why are pulsars hot?
Pulsars and neutron stars are hot because of all the residual heat left over in the core of the original star.

Two types of heat in are earth?
radioactive decay and residual heat
What is the source of heat in the mantle?
Source of heat in mantle come from radioactive decay of the radioactive elements inside the earth..
What is the heat of the core caused by?
the heat form the core is made by Atoms.
What keeps the earths core so hot?
light and heat(i heard some1 say radiation 1ce but i dont think its true)
Can an electromagnet create a magnetic field when the battery is removed?
If the electromagnet has a core, which has become magnetized, then the core will have a residual magnetic field when the power is removed.
