# The P-waves have a speed of about 6 km/s. How do you estimate the average bulk modulus of Earth's crust given that the density of rock is about 2400 kg/m3. Answer the question in Pa?

##
Earthquakes at fault lines in Earths crust create seismic waves, which are longitudinal (P-waves) or transverse (S-waves).

The bulk modulus is

#### Explanation:

Apply the equation

Here,

The density of the rock is

The speed of the

Therefore,
