Final answer:
The statement is correct: secondary (shear or transverse) waves cannot pass through the outer core of the Earth as it is liquid, and these waves cannot travel through liquid. We can obtain information about the Earth's interior from these types of seismic waves.
Step-by-step explanation:
That statement is correct. The secondary waves, also known as shear or transverse waves, can not move through the Earth's outer core. This is because this part of the Earth is liquid and these types of waves are unable to travel through liquid. They are only transmitted through solid mediums. This contrast with compression or longitudinal waves which can pass through liquids and do go through the core. Information about the physical state and temperature of the Earth's interior can be estimated from these seismic waves produced by earthquakes. This is also why when an earthquake occurs, we observe two distinct wave types (P-waves and S-waves).
