If no one has ever visited the core of the Earth,how do we know that it is make of metals? - es metal core scooter wheels
A. Core Material filtered by volcanoes in the crust
B. You can not fool me, it is shown that the core is made of metal.
C. spectroscopy allows us to say that is the core of the analysis of the light that we see the same done
D. The amount of radioactivity in the sample must be present, only radioactive metals
E.circulating liquid metal into the core of a large (measurable quantity) magnetic field

E.circulating liquid metal into the core of a large (measurable quantity) magnetic field
I remember during my Earth Science College
A, D and E. In addition, the average density of the earth in accordance with what above all made of iron.
Material - mainly volcanic layer, but some of the material of the upper portion of the database that are made by convection.
D - the heat inside the earth is obtained from the radiation. Only radioactive metals have half-lives of billions of years.
E - the dynamo that makes the earth's magnetic field is defined in the region of convection on the "core" of seismology. If E is correct, then A is also correct.
All answers are somewhat problematic.
E and only E.
It may be because he mantle material that is filtered through volcanoes.
In fact, only E.
The others are not valid at all.
E alone.
