Why Is The Inner Core A Solid If It Is The Hottest Layer?


How can the Inner core of Earth be solid?

The Inner core is the hottest layer; it has the strongest magnetic field and has the least mass. How can it be solid when other layers aren’t? edit: With that amount of magnetic strength how do the electrons flow through the solid? I think the inner most core of Earth is made up of photon like particles.

At some point of depth in the Earth's interior, around 5150 km, is the transition from the liquid outer core and the solid sphere of the inner core, a ball of incredibly hot iron-nickel alloy. Temperatures here reach between 5,000 and 7,000 degrees C, and pressures are calculated to be around 3,000,000 units of sea level atmospheric pressure. Despite the high temperature, at these pressures the metals cannot remain molten.

What is the evidence that Earth’s inner core is solid? Even though the inner and outer cores are both predomin?

What is the evidence that Earth’s inner core is solid? Even though the inner and outer cores are both predominantly composed of iron and nickel, the inner core is solid and the outer core is liquid. Why? thanks

The evidence is from Earthquake waves, P waves can travel through both solid and liquids whereas S waves can't, therefore not being able to go through the Earth's core. Also the Earth's magnetic field. The inner core is solid because of the pressure within the centre, where as the liquid on the outer core is ductile (is like plastic it stretches).

Hope this helps.

What are the two main metals that make up the outer and inner core?

1.What are the two main metals that make up the outer and inner core? 2.What is the explanation for the outer core being liquid and the inner core being solid? 3.Summarize in your own words, the scientific explanation of the formation of earth's layers

1. Nickel Iron

2. pressure temperature relationships control the phase of the constituants. P-T relationship is such than the core is solid and the outer core is solid( more or less, it probably could be defined as plastic)

How can the earth's inner core be solid while the cooler outer core is a liquid?

How can the earth's inner core be solid while the cooler outer core is a liquid? How can the deep mantle remain solid while the cooler asthenosphere is close to its melting point?

What is beneath the surface of a planet?

For instance, earth has a solid surface composed of mostly water... But what is then beneath the surface? For those who don't understand my question... Does the planet earth, and all other planets with a solid surface, have a core? What's in that core? Does life exist only on the surface of earth? If so, what lies beneath this surface?

Hi Elise! Planet guts will vary dramatically depending on many factors like size, how it was created, what it was created with and it's distance from the sun among others.

The Earth has a solid outer surface made of rock sections or "plates" that are many hundreds of miles thick. These plates "float" on top of a layer of hot liquid rock called a "mantle". Deeper below the mantle layer at the center of the Earth is a "core" of hot molten liquid iron.

In very simple terms....Imagine a round bubble with a smaller bubble inside at the center. The small bubble would be the core, the area between the outside surface of the small bubble and the inside surface of the big one would be the mantle, and the outside of the big bubble would be the Earths surface.

Not all planets have these layers. Mars(the planet, not me) is believed to be "dead" inside, meaning it's core and mantle layers have cooled off enough to become solid.

Why does the Earth stay hot inside? There's several reasons but the simplest way to understand this is to think about a baked potato and what happens when it sits on your dinner plate.

What part of the potato gets cold first? The skin does!(like earths surface).
