Why the Earth’s core does not melt the planet scientists gave the answer
(ORDO NEWS) — The earth’s core consists of an alloy of iron and nickel with impurities of other chemical elements.
The surface layer of the core is heated up to 6000 ° C. But at the same time it does not melt our Earth at all. Why is this happening, scientists have found out. This is reported by Science Focus.
The distance from the upper boundary of the core to the surface of the Earth is only 2900 km. If the sun were so close, it would burn and melt our planet. So why doesn’t the core destroy the planet from the inside?
First, there is a hard rock around the core – a mantle. The crust on which we live floats on this mantle. We do not stand still because tectonic plates are always moving. And of course the difference between temperature and heat should not be confused.
Temperature is energy density and heat is energy itself. Scientists gave an example on a Bengal fire. When we light it up, the temperature of the spark reaches 1500 ° C. However, it will not harm you. But boiling water (boiling point 100 ° C) can kill. This is because there is much more thermal energy in a container with boiling water.
In order for the core to melt the Earth, it needs much more thermal energy than it has. Fortunately, we live in optimal conditions, and the sun is very far from us.
