Keeping this in view, is Earth's core cooling?
The Earth's inner core is thought to be slowly growing as the liquid outer core at the boundary with the inner core cools and solidifies due to the gradual cooling of the Earth's interior (about 100 degrees Celsius per billion years).
Furthermore, what would happen if the core of the Earth cooled? If the core were to cool completely, the planet would grow cold and dead. Cooling also could cost us the magnetic shield around the planet created by heat from the core. This shield protects Earth from cosmic radiation. The shield is created by a convection process caused by constantly moving iron.
One may also ask, what keeps the core of the Earth hot?
There are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive elements.

How long before our sun dies?
The most probable fate of the planet is absorption by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet's current orbit.Why did Mars lose its magnetic field?
Solar wind–induced ejection of Martian atmospheric atoms has been detected by Mars-orbiting probes, indicating that the solar wind has stripped the Martian atmosphere over time.Can the earth's core stop spinning?
The cause of the mayhem? It seems Earth's core has stopped spinning! So much for fiction. In fact, for at least the last 160 million years, as known from evidence preserved in the geological record, Earth's magnetic field has often reversed polarity.Does the Earth's core heat the earth?
Heat flow from the core is necessary for maintaining the convecting outer core and the geodynamo and Earth's magnetic field; therefore primordial heat from the core enabled Earth's atmosphere and thus helped retain Earth's liquid water.Why can't we dig to the center of the Earth?
It's the thinnest of three main layers, yet humans have never drilled all the way through it. Then, the mantle makes up a whopping 84% of the planet's volume. At the inner core, you'd have to drill through solid iron. This would be especially difficult because there's near-zero gravity at the core.How hot is the Earth's core?
