Iron is not formed in the earth's crust. Most of the Earth's supply of iron is located in the Earth's core. Scientists hypothesize that as Earth was transforming into the planet we know today, iron was prevalent on the surface. However, iron was denser than its surroundings and sunk downwards. As this occurred over the Earth, the iron was eventually deposited in the core. Traces of iron can still be found in the crust, however.

Originally, the iron would have been created in the later stages of the nuclear fusion that took place in some nearby star. The iron would have been blown into space when the star became a nova at the end of its life and was eventually captured by the gravity of our sun.
What else can I help you with?
How iron forms?
It is formed when the Earth was being formed. As the Earth got bigger the iron seeped into the crust of the earth and kept going.
How is iron formed naturally in the Earth's crust?
Iron is formed naturally in the Earth's crust through a process called sedimentary deposition. This occurs when iron-rich minerals are weathered and eroded from rocks, then transported by water and deposited in layers. Over time, these layers become compacted and cemented, forming iron ore deposits.
Why do scientist think earth core contain iron?
Samples of Earth's crust contain less iron than found in meteorites, and iron is a comparatively heavy element that would have sunk into the planet when it was being formed.
How are elements up to and including iron formed?
Iron is formed in the final fusion burn of a dying star. After that it has no more fuel to burn and collapses to form either a white dwarf, neutron star, or black hole depending on its mass at the time it runs out of fuel.
Is earth crust made out of iron?
Earth's crust is made up of 5% (by weight) iron No. It's made out of pizzia.
Why do scientist think earth's core contains iron?
Scientists believe Earth's core contains iron because of its density and magnetic properties. Iron is a dense element, which is consistent with the high density of Earth's core. Additionally, observations of Earth's magnetic field suggest the presence of iron in the core.
Why do scientists think Earth's core contains iron?
Samples of Earth's crust contain less iron than found in meteorites, and iron is a comparatively heavy element that would have sunk into the planet when it was being formed.
What two metals make up earth's crust?
The two most abundant metals found in the Earth's crust are aluminum and iron. Aluminum is the most abundant metal, making up about 8.1% of the Earth's crust, while iron is the second most abundant, making up about 5.0% of the Earth's crust.
What is the percentage of iron in the earth crust?
In terms of weight, iron makes up approximately 5% of the earths crust, the fourth most abundant element in the crust. However, remember Earth's Core is nearly all Iron.
Is the iron is formed under Earth's crust?
No. the element iron requires the heat and pressure of a sun like ours to be able to form iron atoms. But our Sun did not produce the iron we have. The iron we have on Earth was made in a larger star that went nova.This iron was amongst the debris field from which coalesced the Earth.In early times, when oxygen levels were quite low, it is believed that much of the iron would have been dissolved in the oceans and they would have been rather green. After the algae invented photosynthesis, this increased the O2 content of the atmosphere, and the iron was precipitated out as the Banded Iron Deposits, which form much of the important iron deposits worked today.
In what era was the earth's crust formed?
precambrian
Is Earth's crust made up of iron?
yes most is made of iron
