Why is the study of seismic waves so useful?
Because is essential for knowing more about earthquakes
Because we can figure out the internal structure of the planet
Because we can get information about the external composition of the planet
What are the two fundamental types of seismic waves?
P waves and S waves
L waves and R waves
Surface and body waves
What are the two types of body waves?
Point two different properties of the S waves
They arrive first and can travel through solid
They arrive second and can travel through liquid
They arrive second and can travel trough solid
Regarding to P waves characteristics, how can we know the outer core is liquid?
P waves reach first the outer core
S waves cannot travel through outer core but P waves do
P waves are better known than S waves
