The center of the Earth is a solid ball of iron-nickel alloy called the inner core.
The Inner (solid) and Outter (liquid) Core are made up of Nickel and Iron.
They show that the outer core of the Earth is liquid while the inner core is solid.
no it is not true. there is solid iron and nickel in the Earths core
The solid state of of the inner core is due to pressure caused by the weight of everything above it.
the outer core is liquid; the inner core is solid
Scientists use the difference in density between the inner and outer core as evidence that the inner core is solid. This was proven using seismic waves traveling through the earth.
They go faster through the inner core than the liquid outer core.
a solid ball of iron
Scientists believe Earth's inner core is solid because of seismic waves from earthquakes that travel through the core, the behavior of seismic waves, and the way in which they are reflected or refracted. This information suggests that the inner core behaves more like a solid than a liquid. Additionally, studies of the Earth's magnetic field and the behavior of seismic shear waves also support the idea of a solid inner core.
the inner core
Yes the refraction path of the p-wave tells us that the earths inner core is solid.
The immense pressure from the layers outside of the inner core.
It is said that the crust and the inner core are to be solid.
The solid inner and liquid outer core.
The inner core Is solid and the outer core in liquid
An alloy of solid nickel and iron, mostly.
