Iron is denser than rock, and therefore sinks through the layers of molten liquid rock, to the center.
80% iron and some nickel. Then the rest is smaller elements
It is supposed that the Earth core is composed from iron and nickel.
the inner core
the inner and outer core
The Earth's outer core is composed of liquid iron & nickel
Mostly iron, oxygen, silicon, magnesium, sulfur, nickel, and calcium.
The three main layers of the earth are the Core, Mantle and Crust. The Core is mostly made from iron and nickel, the Crust from oxygen, silicon and aluminum and the mantle silicon,oxygen,iron and magnesium.
The Inner (solid) and Outter (liquid) Core are made up of Nickel and Iron.
earth is made of two types of gasses that is 78% Nitrogen and 21% oxygen
Earth is mas mostly of silicate minerals with a core made mostly of iron and nickel.
The Inner Core
The core
Earth's crust is mostly made up of Silicon and Oxygen
The earth is mostly made up of the element iron, which comprises 32% of the planet. An interesting fact about the composition of the earth is that 70% of its surface is covered with water.
The inner and the outer core of the earth are made up iron and nikel mostly.
Our earth is mostly made up of silicon oxide (sand) and magnesium oxide, extending from the outer core to the crust. The inner core is mostly iron, enriched to 4% nickel. About 70% of the surface is covered with water.
Earth is covered mostly in water, but is not made up mostly of water. Most of earth is made of rock.
The earth's core is made up of the elements iron and nickel.
The outer cores is made up of mostly iron and nickel in a liquid state.
yes most is made of iron
Earth's crust is made up of 5% (by weight) iron No. It's made out of pizzia.
