| What underneath the asthenosphere | |
 | |  |
|
 |
 | |  |
| The mantle is where the p and s waves travel through to get the outer and inner core.they bend and refract as they enter the core | |
 | |  |
|
|
|
|
|
|
|
 |
 | |  |
| The liquid from the the outer core causes the p waves to refract and s waves cant travel through this core being they cant travel through liquid and arent felt. | |
 | |  |
|
|
|
|
|
|
|
 | |  |
| what about the inner mantle? | |
 | |  |
|
 |
 | |  |
| The inner mantle is solid and the p waves will once again refract as s waves can travel regularly on the p waves path. | |
