Is earth divided by composition into three layers?

The 3 main layers of earth (crust, mantle, core) are divided into crust, upper mantle, lower mantle, outer core, and inner core.


What is neptunes core composition?

Well, It has about an Earth sized core made of rock material. The core is also surrounded by a layer of liquid that's possibly a water, methane and ammonia mixture. The core temperature is about 100 degrees Celsius.


Layer of molten iron and nickel that surrounds the inner core?

Information about these regions is obtained from the travel of seismic waves, and from high pressure laboratory studies. The inner core is solid because of the intense pressure due to gravity. The outer core is of quite similar composition, but under lower pressure, it remains liquid. Both regions are believed to be mainly iron and nickel, though there will be significant quantities of other heavy metals as well, including radioactive ones. It is because of heat released by these radioactive materials that the outer core is molten. (and by conduction and convection to the magma. )


Which changes occur in the composition of the earth's interior layers as you move toward the core?

I think its the last one. The material is hotter and denser. I'm doing the assessment now. ^ Brinaq: K12 FTW! ^ Kiwi: Yeah K12 FTW!


What is the liquid layer of the Earth's core called?

Based on the physical properties of the earth;The core is divided into outer core and inner core.the liquid layer of the earth core is the outer core,while the inner core is solid.
