Earths nickel brought by meteorites

Earth's nickel brought by meteorites

I watched a VOD last night about meteorites. The pic here is the impact crater at Sudbury, Canada. It produces 30% of the earth's nickel! The video went on to say that it is believed that ALL of the earth's nickel was brought by meteorites. Any comments? TTC

I ran across this page recently.
Says the planets core is high nickel.

I found the plant connection quite interesting...

"Nickel is essential for healthy plant life. As a result, it is found naturally in most vegetables, fruits and nuts, and in the food products derived from them, for example – chocolate and wine."

Isn't Earth's core believed to be the same as meteorites, iron & nickel?

I find it interesting that earth rock have little nickel iron but the rest of the universe seems to have mostly nickel iron. Has the earth been made differently than the rest of the universe?

Earth has a very active crust. Plate tectonics assures us that every few million years earth will "recycle" the inside AND crust of our planet. In its formative years, earth was molten, allowing the heavier (iron/nickel/gold etc) minerals to "sink" to its core. Volcanism redistributes those heavier things back to the surface. Your "earth made differently than the rest of the universe" statement only reflects the state of our scientific knowledge of the universe. Not much. As we learn how to identify and "decode" more exoplanets, we will find some that are more like earth, having active crusts. I am not a scientist but hope I have answered your question(s). TTC

I don't know if you are into 'numbers' or not, but at 1:33 ctz you had 4,444 posts! I know that I should have waited until 4:44 pm to send this, but oh well.

Enjoy the Day

Hey Tom! Good to hear from you! The number's thing never occurred to me. Good thing no one brought them up when it was 666! I'd still be under my bed!! Take care my friend. Terry

The earth is nothing but a collection of meteorites,we are on a big a$$ meteorite

Here's what's left of the nickel-iron meteorite that made the "Impact Crater" outside Flagstaff, AZ.

I have a piece of the Meteor Crater, AZ meteorite. My uncle says the original mass is still underground.
