Evidence that earths core has a high iron content comes from?
As material accumulated to form Earth, the high-velocity impact of meteorites and the decay of radioactive elements caused the temperature of our planets to steadily increase. During this time of intense heating, earth became hot enough that iron and nickel began to melt.
How are inner core and outer core different?
The inner and outer core are different because of the difference in vertical stress within the Earth. As the confining pressure increases it drives up the melting temperature of materials (in this case iron and nickel). The boundary between the outer and inner core marks the point where the confining pressure is so high that it drives the melting temperature of the core material above the temperature within the core. As such it is no longer hot enough to melt the iron / nickel mixture and it solidifies.
Why might a very hot rock might not melt?
it might not melt if it doesnt have fluid in it
What rock can melt at a depth of about below earths surface?
50km
Why does the rock in the inner core melt?
No. Though the temperature of the inner core of the Earth is about 5700 degrees, (about as hot as the surface of the Sun) the pressure is also very high, about 3.3 - 3.6 million atmospheres. At these pressures, the hot iron - nickel material will still be solid.
How thick is earths inner core?
The inner core is 1216 km and made of solid iron. It is approx 5000 degrees C and it doesnt melt because of everything else pushing down on it.
Why is earths inner core solid even though its temperature is hotter than that which would melt iron?
it is like 62,000,00 degrees down there
Can iron melt in the earth's outer core?
yes.
Why cant you dig through the earth to the other side?
Because the earths core would melt you.
Which layer is melted material?
(The layer that is melted material inner core, the inner core can melt iron & nickel.)
Why is the core solid even though it is hot enough to melt?
This super hot iron cannot melt because of all the pressure.
How do you get to the core of the earth?
you can't get to the earth's core it's to deep, you would melt from the lava, and if you did get to the core you would disrupt the earths magnetic field and we would be killed by a solar storm.
How do you iron bubble wrap?
Steam, hold it quiet high above the steam so it doesnt melt.
Is the the inner core a liquid?
At the massive pressures that exist there, the iron and nickel cannot melt despite the high temperatures.

What chemicals to use to melt iron or steel?
which chemical is used to melt the iron
Where does the energy needed to melt the iron come from?
The energy comes from the heat to melt the iron
