Try a HSC Earth and Environmental Science question
Which observation provides the strongest evidence that Earth’s outer core is liquid?
- P waves speed up at the Mohorovičić discontinuity
- Iron meteorites are made mostly of iron–nickel alloy
- Direct S waves are not recorded beyond about 103° from an earthquake
- Jack Hills zircons are about 4.4 billion years old
Show the worked answer
Answer: C
S waves are shear waves and cannot travel through liquids, so a liquid layer at about 2900 km depth blocks them and creates the S-wave shadow zone. A describes the crust–mantle boundary, B suggests core composition rather than state, and D concerns age.
