Q.26. Which of the following earthquake waves is first recorded on the Seismograph?

(A) P-waves

(B) Rayleigh waves

(C) S-waves

(D) Love waves

Explanation:

P Waves: (Body Waves)

Primary waves are called so because they are the fastest among the seismic waves and hence are recorded first on the seismograph.

They can travel in all mediums, Solids > Liquids > Gases.

S- Waves: (Body Waves)

Secondary Waves

S-waves arrives at the surface with some time lag.

They can travel T only through solid materials

L waves (Surface waves):

Last to report on seismograph.

These waves are more destructive.

They cause displacement of rocks, and hence, the collapse of structure occurs

Q.27. The average density of the Earth is

(A) 5.5

(B) 5.15

(C) 5.517 g/cm3

(D) 5.555 g/cm3

Explanation:

Q.28. Which of the following earthquake waves are most destructive?

(A) S Waves

(B) P Waves

(C) R Waves

(D) L Waves

Explanation:

L waves (Surface waves):

Last to report on seismograph.

These waves are more destructive.

They cause displacement of rocks, and hence, the collapse of structure occurs

Q.29. Which seismic waves can pass through solid and liquid materials?

(A) P. Waves

(B) S. Waves

(C) L. Waves

(D) PG–SG Waves

Explanation:

Explanation:

Q.34. The main causes of Tsunami are

(A) Explosion of Volcano

(B) Strong earthquake in the ocean

(C) Cyclone in the Ocean
