Explanation:
she ends up with a displacement of 5km north of her house and a distance of 3km
Speed=wavelength×frequency
speed= 0.005m × 10 Hz = 0.05m/s
The asthenosphere is thicker than the lithosphere, where the speed was faster.
<h3>
Velocity of S wave</h3>
The velocity of s wave decreases as the thickness of the Earth layer increases, because it will take more time to travel through the given thicker formation.
The magnitude of velocity is given as;
v = x/t
where;
- x is the thickness of the Earth layer
- t is the time of motion
This implies that the speed of the s wave will high in thin formation and low in thick formation (layer).
When the velocity of S wave decreases as the waves leave the lithosphere and enter the asthenosphere, it implies that the asthenosphere is thicker than the lithosphere, where the speed was faster.
