Question

which layers can S-waves go through?
-outer core, inner core, and crust
-inner core, outer core, and mantle
-outer core, mantle, and crust
-inner core, mantle, and crust

Answer 1

S-waves, or secondary waves, are a type of seismic wave that cannot travel through liquids. Given this property, S-waves can only travel through solid materials. Therefore, S-waves can pass through:

- **Inner core**
- **Mantle**
- **Crust**

S-waves cannot travel through the **outer core**, as it is liquid. So, the correct answer from your options is:

**Inner core, outer core, and mantle** (though this option is misleading because S-waves do not travel through the outer core, so it is not a viable option).

The more correct interpretation based on the understanding of S-wave propagation is:

**Inner core, mantle, and crust** (S-waves pass through these layers). However, such an option was not provided in your initial list. If you have another choice or need clarification, please provide that context.
