As a "lay man"...The Earth, and it's core formed from the debris left over from the gases and accretion disk our Star (Sol) formed out of. The collisions of the rocky and metallic debris formd a globe (Earth) whose gravity attracted more and more material. Eventually the core compressed into what it is today. Planetary Scientists and Geologists freely admit to not having a good understanding of just how the core interacts with the Earth's mantle, but they have several good theories. They know the Earth's magnetic field, essential in protecting us from cosmic radiation, is generated by the core and the Earth's rotation; yet they don't fully understand how or why the magnetic field changes over time.
What else can I help you with?
How much of earths mass made up by the core?
The core is 33% of the Earths mass
How are the Earths magnetic field made?
It is made by the movement of the earths core and magma field
Earths core is made of an alloy of?
earth core is made of an alloy of.... MOSTLY IRON AND NICKEL
What is earths core made out of?
hydrogen carbon and nitrogen
Which the earths core is made of more medal?
both of them
How the Earth's magnetic field is made?
It is made by the movement of the earths core
What is earths core mostly made out of?
The Inner (solid) and Outter (liquid) Core are made up of Nickel and Iron.
Is the earths outer core made of solid metal?
No it is liquid
What is the center of the earths interior made of mostly of iron?
core
What is earths core mostly made of mostly?
basalt and granite
Are you closer to the earths core or moons surface when standing at sea level?
Earth's core
Is the earths core made of hard rock?
No. The Earth's core is divided into two parts: a solid inner core and a liquid outer core, moth made mostly of iron.
