Is the world really going to end
we drill very deep in the earth .
we know whats inside the earth because there is earthquake wave
how do we know about the earth's layers when we never drilled that far down?
i don's know
we know about the core of the earth by mining and all the other digging things.
There are many planets in the universe, but as far as we know there is only one Earth, therefore I do not know to which "other earth" you are referring.
i want to know the wisest person on the earth
the three ways in which we know about the interior of the earth are:volcanoesearthquake waves-under the earthdrilling
There is no way to know the destiny of earth.
The center of the earth is the inner core.
You just know
The Earth as we know it.
