Question 43

two main types of seismic wave:

Accepted Answer

body waves

Accepted Answer

surface waves.

Question 44

There are two types of body wave

Accepted Answer

primary, or P

Accepted Answer

secondary, or S,

Question 45

Each type of body wave has a characteristic speed and manner of travel.

Accepted Answer

true

Answer

falkse

Question 46

which nis true about the p wave

Accepted Answer

P waves push and pull particles in the direction the waves travel.

Accepted Answer

P waves are compressional waves.

Accepted Answer

The particles of a P wave move forward and backward, producing a relatively small displacement. The rock material alternately squeezes and stretches as the P wave passes through it. It can travel through solids and liquids.

Accepted Answer

This type of seismic wave travels twice as fast as S waves do.

Question 47

which is true about s wave

Accepted Answer

S waves shake particles at right angles to the direction the waves travel.

Accepted Answer

S waves are shear waves

Accepted Answer

The particles of an S wave vibrate back and forth at a right angle to the direction the wave travels. As this wave passes through the material, it causes strong movement.

Accepted Answer

This type of seismic waves can travel only through solids. When body waves reach the surface, they produce surface wave

seismogram picks up the P wave first,

Accepted Answer

the S wave, second

Accepted Answer

the surface waves.

Question 53

Accepted Answer

true

Answer

false
