Why the Earth's Core Is Hotter Than the Sun

We’ve managed to go hundreds of thousands of miles into space, but when it comes to the earth, we’ve barely scratched the surface. Our planet’s core is a magnificent mystery filled with secrets. It’s time to figure them out.

The Earth’s inner core is an extra hot solid ball that has a radius just 30% smaller than the Moon. Scientists figured out that most of the Earth’s mass is located towards the center of our planet. The temperature of the inner core is about 9800°F. While the melting point of pure iron is about 2,800°F, at the core, its melting point is around 11,000° F.

SUMMARY:
-It’s estimated that the Earth’s mass is 5.6 sextillion tons. More than 80% of the core consists of one of the ten most common elements in our galaxy: iron.
-In 2013, Wendy Mao and her team from Stanford discovered a possible solution for how this happened. During their experiment, molten iron slowly squeezed through the silicate rocks, and they had their answer. It took millions of years for the iron to reach the center, so it happened at a snail’s pace.
-During an earthquake, shockwaves are spread through the planet. Seismologists study these vibrations and try to read the reflections on the other side. As science progressed, it turned out that picky “S-WAVES” could only go through solid material, and not liquid. So something molten was present in the center of the Earth that was preventing the vibrations from going through.
-The temperature of the inner core is about 9800°F. While the melting point of pure iron is about 2,800°F, at the core, its melting point is around 11,000° F. The fluctuation in those temperatures comes from factoring in the extreme pressure the iron is exposed to at the core.
-The reason it remains solid is because of the slow cooling of the outer core and its compression. The inner core spins faster than the Earth. That’s caused by the thermal activity inside our planet which creates the magnetosphere.
-The first reason the Earth is still boiling is that the core has remained hot from the time our planet was formed – roughly 4.5 billion years ago. Secondly, it generates heat from the friction of the dense materials as they move. And the last reason it’s so hot is from the decay of radioactive elements.
-A 2015 study from Durham University claimed that 90% of the Earth’s sulfur is in the core. When the impact happened, the Earth’s mantle melted, and some sulfur-rich liquid squeezed through the ruins and reformed it. Some of it was probably lost in space, but the rest sunk to the core.

Its hotter than the surface of The Sun.

The core of The Sun is a different story...

The answer is the earth has learnt to control its anger and the sun just lost it completely.

THIS QUESTION APPEAR WHEN YOU'RE IN THE BED AT LATE NIGHT AND CAN'T SLEEP. SO YOU SEARCH FOR EVERYTHING COMES IN YOUR MIND, like:

The interior of Earth is very hot (the temperature of the core reaches more than 5, 000 degrees Celsius) for two main reasons:

The heat from when the planet formed,

The heat from the decay of radioactive elements.

The Earth was formed by the process of accretion. After the creation of our solar system, each other and formed bigger objects, which attracted bigger masses, until our planets reach their current size. This process accumulated a lot of heat.

Scientist :Too hard to discover how hot the earths inner core is
Also scientist : the sun is simply 27 million degrees Fahrenheit

i find it amazing that the earth's core is hotter than the sun yet despite this with just a little less sunlight the planet would completely freeze over.

The Earth's core is not technically hotter then the sun, the core is hotter then the surface sure, but core Vs core, no contest

1:15 "There is a simple explanation. It got there somehow."
Wow, thanks, science! But could you "cool it" with the scientific jargon? "Somehow" it's over my head.

I am a huge fan of this series overall, but this video shows that there is a great deal of guesting when it come to science. We can not for 100% say that these "facts" are actual facts because we can not test the actual substance(s) themselves. At best these are estimations and hypothesizes.

I still heard lots of theory, without proven scientific facts. Sometimes we don't know, IS the most correct, and truthful answer.
