which layers can s-waves go through?

Question

outer core, mantle, and crust.
inner core, outer core, and mantle.
outer core, inner core, and crust.
inner core, mantle, and crust.

Answer 1

S-waves (shear waves) can only travel through solid materials and cannot pass through liquids. Given the Earth's layers:

• Outer Core: This layer is liquid, so S-waves cannot travel through it.
• Inner Core: This layer is solid, so S-waves can travel through it.
• Mantle: This layer is mostly solid, allowing S-waves to travel through it as well.
• Crust: This is also solid, so S-waves can travel through it.

Based on these properties, S-waves can travel through the inner core, mantle, and crust.

So the correct answer is: inner core, mantle, and crust.
