Inner core: Iron and nickel
Outer core: Iron, nickel, and oxygen
Oceanic crust: Basalt, magnesium, and iron
Continental crust: Granite
Mantle: Iron, magnesium, and calcium
I hope this helped now all I need is a way to remember them all!

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.
Which layer of earth is made of extremely dense solid metal?
The inner core of the Earth is believed to be solid and composed mainly of iron. The 4 layers of the Earth include the crust, the mantle, and the inner and outer cores.
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.
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 main difference between inner and outer core of earth?
The inner core is located below the outer core with a reasonably higher temperature. The outer core also contains elements such as liquid iron and nickel while the inner core has others. Sorry if I am not being giving a huge amount of details.
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?

What two metal are in the inner and outer core?
Iron and nickel compose the bulk of the inner and outer core of the Earth.The bulk of the inner and outer cores, around 80%, are composed of iron. A substantial amount, around 10%, is composed of nickel, and the remainder is a mixture of other elements.

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.
