2
Q
What is used to detect seismic waves
A
Seismometers
3

What happens when seismic wave reach a boundary
A
Some waves are absorbed and some are refracted
4
Q
What are 2 the types of waves
A
P-waves and S-waves
5
Q
P-waves
A
-longitudinal
-travel through solids and liquids
-faster than s-waves
-go through the core
6
Q
S-waves
A
-transverse
-can’t travel through liquids
-no s-waves detected on the other side of the earth
7
Q
What are s-waves and p-waves caused by
A
Earthquakes
8
Q

A
-crust (solid)
-mantle (very hard liquid)
-outer core (liquid)
-inner core (solid)
