Earth's inner core was formed 1-1.5 billion years ago
Science Daily ^ | 10/7/2015 | University of Liverpool

There have been many estimates for when the earth's inner core was formed, but scientists from the University of Liverpool have used new data which indicates that the Earth's inner core was formed 1 -- 1.5 billion years ago as it "froze" from the surrounding molten iron outer core.

. . . .

In a new study published in Nature, researchers from the University's School of Environmental Sciences analysed magnetic records from ancient igneous rocks and found that there was a sharp increase in the strength of the Earth's magnetic field between 1 and 1.5 billion years ago.

This increased magnetic field is a likely indication of the first occurrence of solid iron at Earth's centre and the point in Earth's history at which the solid inner core first started to "freeze" out from the cooling molten outer core.

Just in time for life to spread under the protection of a stronger magnetic field.

Didn’t Al Gore tell us that the earth’s core is ‘several million degrees”?.

this flow of energy should keep the Earth's magnetic field going for another billion years or more.

That's reassuring.

I think the standard estimate for the age of the Earth is 4.5B years.

So Earth was formed first, and then 3B years later, the core formed?

What?

Seems like “science” has been pulling a lot of bold claims with no evidence out of its butt lately. Water on Mars for example,

I think the concept is that there was a core, and that over time it separated into an inner core and an outer core.

I think it is a scam to get research monies so they don’t have to go on unemployment.

He also said trees give off CO2, and he said that in the movie he made so it’s not like it was a mistake, he didn’t have it corrected, didn’t edit it out, he left it in because that’s what that idiot believes. He’s a flim flam man who goes around portraying himself as a climate scientist when he doesn’t know the first damn thing about the climate or science. He also said 10 years ago the earth would burn up. Here we are 10 years later and nothing has changed. Rush has been keeping count on that as well...........

Before the core formed the center was all molten. The hard ball of solid iron at the center is what is new.

Agreed, great example.
