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
How are inner core and outer core different?
The inner core is solid due to high pressure and temperature, while the outer core is liquid. The inner core is composed mainly of solid iron and nickel, while the outer core is also made of iron and nickel but in a liquid state.
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.
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 thick is the earth core?
1. Inner Core - A mass of iron with a temperature of about 7000 degrees F. Although such temperatures would normally melt iron, immense pressure on it keeps it in a solid form. The inner core is approximately 1,500 miles in diameter. 2. Outer Core - A mass of molten iron about 1,425 miles deep that surrounds the solid inner core. Electrical currents generated from this area produce the earth's magnetic field.
Which layer is melted material?
The melted material is typically found in the outer layer of the Earth's interior known as the mantle. This layer lies between the crust and the core, and its high temperature and pressure conditions can cause rocks to partially melt, creating magma.
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.
Is the temperature of the outer core higher OR lower than its melting point?
The outer core is liquid. Its pressure is low enough and its temperature high enough for it to melt. The inner core is solid. Both its pressure and temperature are higher than the outer core, but the increased pressure overwhelms the increased temperature, keeping the inner core from melting.
Is the asthenosphere a true liquid like the outer core?
No. The asthenosphere is thought to contain only around 5% 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.
Why is the earth's outer core liquid but the inner is solid?
The outer core is liquid because it is under high pressure which lowers the melting point of the metals present in it. The inner core is solid because the immense pressure at the Earth's center, combined with the high temperature, keeps the iron and nickel in a solid state.
