Question

is the knowledge of Earth's interior based on indirect observation​

Answer 1

YES,

THE KNOWLEDGE OF THE EARTH'S INTERIOR IS BASED ON INDIRECT OBSERVATIONS LIKE TEMPERATURE INSIDE THE EARTH, PRESSURE INSIDE THE EARTH, VARYING DENSITY OF THE INTERIOR OF THE EARTH AND STUDY OF THE EARTHQUAKE WAVES...

THE KNOWLEDGE OF THE INTERIOR OF THE EARTH IS BASED ON INDIRECT OBSERVATIONS INSTEAD OF DIRECT OBSERVATIONS BECAUSE, EVEN THE DEEPEST MAN MADE HOLE ON THE EARTH IS ONLY 8 KM DEEP WHICH IS QUITE INSIGNIFICANT WHEN COMPARED TO THE MEAN RADIUS OF THE EARTH (6378 KM)..

THUS WE NEED TO DEPEND ON THE INDIRECT OBSERVATIONS...

I HOPE THIS ANSWER HELPS YOU...
