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.

Which layer in the Earth is similar in composition to an iron-nickel meteorite?
The core, both the inner and outer cores are primarily nickel and iron.
Why do scientist use ice cores?
to find out what the composition of the atmosphere was
Why is it necessary to think about the different layers of the Earth in terms of both their composition and their physical properties?
There's different layers when you define them differently, for example, when you define under physical you have the - lithosphere - asthenosphere -mesosphere - cores ( outer and inner cores ) and under compositionall you have - crust - mantle (split into several categories) - inner core - outer core you're going to miss vital information if you define it just one way, for example - if you define using composition, you will not know that the core is both liquid and solid, etc.
What is the composition of Earth's inner and outer cores?
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 type of evidence acts as a record of changes in organisms over time and indicates major changes in earths surface and climate?
the composition of ice cores
Which layer in the Earth is similar in composition to an iron-nickel meteorite?

What is the difference between the inner cores and outer cores?
The inner core is a solid, and the outer core is a liquid.
How many planets have inner and outer cores?
all
Why do scientist use ice cores?

Are the outer planets small rocky planets with iron cores?
No
What are outer cores prpopertys?
its responsible for Earth's magnetic field.
What is the outer cores function?
creating earth's magnetic field:)
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. :)

Does the core contain the lower mantle?
No. The outer and inner cores are separate from the mantle.
