What does rock physics mean?

• To smash physics :)

• Teaching physics to rocks >_<

• physics is hard like rocks

• Studying rock properties using physics

The product of velocity and density is called

• Compressional velocity

• elastic moduli

• Impedance

• none of the above

Assuming elastic condition is met: how many elastic moduli is needed to relate stress and strain when the rock is homogeneous and isotropic

• 1

• 2

• 3

• 4

The higher the resistance to shearing, the higher the shear modulus of the material

• True

• False

If bulk modulus of a rock is 30 GPa and shear modulus is 20 GPa, then poisson's ratio is

• -0.3

• 0

• 0.23

• 0.5

Primary wave has larger amplitude than S-wave

• True

• False
