The Earth's core is thought to be predominantly iron (85 %) with some (4-5%) nickel and the remainder oxygen, silicon, hydrogen and carbon and a number of siderophile (iron liking) elements that descended to the core with iron during planetary differentiation. The inner core is solid and the outer core, liquid.
What else can I help you with?
Which layer in the Earth is similar in composition to an iron-nickel meteorite?
The Earth's core is the layer that is most similar in composition to an iron-nickel meteorite. The core is divided into an outer liquid layer and an inner solid layer, and both contain a high concentration of iron and nickel, similar to the composition of iron-nickel meteorites.
How deep is the border between the outer and inner cores is it from the earth's crust?
the core is 3470km thick (the inner is 1270km and the outer is 930km thick) from the top of the outer layer of the core to the crust is 2850km (called the mantle) , and the crust itself is 25 miles beneath continents and 6.5 miles thick beneath oceans..
What is earths internal composition?
nope i dont know really
What is the outer cores composition?
Of the Earth, both the Inner Core and the Outer Core are believed to consist of a nickel iron mixture. The Inner Core is solid on account of the immense pressure. The Outer Core is a similar chemical composition, but with less pressure it behaves like a very viscous liquid. The Outer Core extends from about 1200 km to 3400km radius.
What is hotter inner mantle or outer mantle?
Oh, dude, the inner mantle is definitely hotter than the outer mantle. Like, we're talking about temperatures reaching up to 4000°C in the inner mantle compared to a measly 500-900°C in the outer mantle. So, if you're looking for a hot spot, the inner mantle is where it's at.
What is the difference between the inner cores and outer cores?
The inner core is a solid, and the outer core is a liquid.
What is the earths cores state of matter?
Soild
What would happen to the temperature of earths inner and outer cores if it keeps losing heat?
It would harden and then become hard rock.
How many planets have inner and outer cores?
All terrestrial planets, such as Earth, Mercury, Venus, and Mars, have inner and outer cores. These cores are composed of mostly iron and nickel, with the inner core being solid and the outer core in a liquid state. Gas giant planets like Jupiter and Saturn also have cores, but they lack a distinct separation into inner and outer regions like terrestrial planets.
The inner and outer cores are probably composed mostly of?
Iron '
How are the inner and outer cores the same?
they are both part of the earth
What is the outer cores most abundant elemant?
The earths outer core's most abundant elemant is silicon. :)
Which of Earth's cores is liquid?
The outer core is liquid; the inner core is solid.
Does the core contain the lower mantle?
No. The outer and inner cores are separate from the mantle.
Which layer in the Earth is similar in composition to an iron-nickel meteorite?
The Earth's core is the layer that is most similar in composition to an iron-nickel meteorite. The core is divided into an outer liquid layer and an inner solid layer, and both contain a high concentration of iron and nickel, similar to the composition of iron-nickel meteorites.
What is Difference between earths inner core and outer core?
The inner core Is solid and the outer core in liquid
How are the compositions of the inner and outer planets different?
A basic, simplified answer is: The inner planets are mainly rock with iron cores. The outer planets are mostly gas, or liquefied gases.
