Why did most of the iron that existed near Earth's surface around 4.5 billion years ago end up in the earth core?

Why does earths surface bulge at the equator?
Because the Earth is spinning - at about 1000 miles per hour at the equator.
What does the earth have more of than land?
The Earth has more water than land. Around 70% of the Earths surface is water and 30% is land.
How do mercury radius and mass compare with the earths?
Mercurys mean radius is around 2,439.7 km, which is around 38.39% of earth radius or 0.3829 Earths. Mercurys mass is around 3.3022×10 to the 23 kg, around 5.5% of earths mass or 0.055 Earths.
What names is given to the molten rock below the earths surface?
Magma. Magma rises towards the surface when it's less dense than rock around it. Otherwise, it collects in magma chambers and cools, forming igneous rock.
What is the surface on which the lithospheric plates move around earths surface?
Lower mantle is the surface on which the lithospheric plates move around earths surface.
How long does the formation of solar systems take?
I would say around 8 billion years. Earth has been around for 5 billion years, and the universe has existed for only 13 billion. In other words, A LONG< LONG< time The universe has existed for 14 billion years. God!!

Has a planet over 5 billion years old crash into our planet?
to correct that it was around 4.6 billion years ago. scientists believe that early in earths days, a body about the size of mars crashed into the young earth flying many debree in earths orbit. it was then believed to form the moon. to correct that it was around 4.6 billion years ago. scientists believe that early in earths days, a body about the size of mars crashed into the young earth flying many debree in earths orbit. it was then believed to form the moon.

Which rocky planet has the strongest gravitational pull?
Of the four inner, rocky planets, Earth is the largest and most massive. As a consequence, it has the highest surface gravity of the four inner planets. The gravity for Venus is around 90% of Earths, while for Mars and Mercury the surface gravity is around 38% of Earths.
What planet has low air pressure and is mostly carbon dixide?
Mars has a thin atmosphere, mainly of Carbon Dioxide. Its surface pressure is around 0.7 kPa, around 0.7% of Earths surface pressure.
