When will Earth's core die out? Will it die out when the sun dies out because it gets heat from the sun?

Heat at 's core is sustained by two things, the downward pressure of everything above it, and, a large deposit of radio active material which also heats the core. has absolutely no effect upon the heat at the core of the earth.

The sun's "death" will be preceded by it becoming a red giant. Many astronomers speculate that this expansion will great enough that the first three planets, which includes the earth, will be enveloped by the sun.

Even if the earth as a planet survived the red giant stage of the sun, the earth will be little more than a dead cinder moving around a dying star.

In a main sequence star the gravity of the core is balanced by the outward pressure of the heat created by fusion of hydrogen atoms, maing it stable. So when the hydrogen is used up, does the star expand to form a red giant because the outward pressure?

When a star's core fuses all of its hydrogen into helium, the core contracts. The temperature and intense pressure caused by the contractions causes helium to begin fusion in the...

When a star less than 8 solar masses runs out of Hydrogen in its core, the balance between outward pressure and gravity is lost. The core then starts to collapse....

What happens to the entropy of the sun and earth system when heat flows from sun to the earth? Will the heating energy increase or decrease during this process? Why?

In all the spontaneous processes where heat is transferred from a body of higher temperature to a body of lower temperature, entropy always increases. To learn why, check...

How long does it take for energy produced in the core of the Sun to reach the earth?

But the Gama rays produced in the core travels through the gases of Sun and takes million years to reach its surface as they collided with atoms...During the travel it...

What are the similarities and differences between the earth's core and the sun's core?

Both of these are similar as they are hot. However as is obvious, one is a planetary core and the other a stellar core, 's core is made up of...

Is the earth's core hotter than the sun?

Sun's core is 15 million degree C and surface is 5800 degree C. So answer is No.

Will our earth's core stop spinning when the sun dies?

When "dies," as you say, it will have first ballooned up into a red giant and will most likely envelope the first 3 planets which of course includes . The...

Which is hotter, the earth's core or the sun?

The Earth's core is thought to be about 6,000°C which is about the same as the surface of the Sun. The centre of the Sun is however much hotter at...

Why do P-waves travel faster through the inner core than the outer core?

The enormous pressure in the inner core means bonds between the (mainly) iron and nickel atoms are ‘squashed’. This raises their energy and consequently their stiffness. The speed of any...

What separates the inner core from the outer core?

Enveloped by mantle-core boundary, the outer core might not be spherical. Propagation of seismic waves, partly with reflection, marks the separation between mantle and outer core. Only primary waves enter....
