How many miles is it through the Earth's core?
I'm not sure what exactly you're asking, but the distance from the Earth's surface at the equator, through the two cores (the outer core and the inner core), to the center of the Earth is approximately 3963 miles.
How many elements make up the earths crust? The earths crust is made of many layers..You can find clay and very good soil. But that is if you dig a little way down. the earth has a center which is called the core of the earth. Inside this core is lava and is incredibly hot. Like the sun but not as hot..
