What scientists learned about Earth by studying seismic waves is “ Seismic waves are not affected by boundaries between earth's layers ”. The correct answer is C.
Scientists studied the seismic waves to be able to properly understand the Earth’s interior. Seismic waves refer to wave energy that moves through the Earth. ;
i believe it could be
C ) Seismic waves are not affected by boundaries between earths layers
Studying seismic waves has revealed that the outer core of the Earth is liquid, as S-waves cannot pass through liquids, creating a shadow zone. Seismic waves, including P-waves and S-waves, provide vital insights into the Earth's internal structure. Therefore, the correct answer is D. The outer core of Earth is liquid.
