1. Question
Consider the following statements with regard to the effects of propagation of earthquake waves:
1. Primary waves create troughs and crests in the material.
2. Secondary waves cause stretching and squeezing of the material.
Which of the statements given above is/ are correct?CorrectAnswer: D
Statement 1 is not correct: Primary waves (P-waves) vibrate parallel to the direction of the wave. This
exerts pressure on the material in the direction of the propagation. As a result, it creates density
differences in the material leading to stretching and squeezing of the material.Statement 2 is not correct: Density difference is created by P-waves (see the above explanation). The
direction of vibrations of secondary waves (S-waves) is perpendicular to the wave direction in the vertical
plane, hence they create troughs and crests in the material.IncorrectAnswer: D

2. Question
Consider the following statements regarding geomorphic processes:
1. The exogenic forces derive their energy mainly from within the earth while the endogenic forces derive their energy from the atmosphere.
2. The actions of exogenic forces continuously elevate the parts of the earth‟s surface, while actions of
endogenic forces leads to wearing down of relief and filling up of depressions.
Which of the statements given above is/are correct?CorrectAnswer: D
The exogenic processes derive their energy from atmosphere determined by the ultimate energy
from the sun and also the gradients created by tectonic factors. While, the energy emanating from
within the earth is the main force behind endogenic geomorphic processes. This energy is mostly
generated by radioactivity, rotational and tidal friction and primordial heat from the origin of the earth.
This energy due to geothermal gradients and heat flow from within induces diastrophism and volcanism in
the lithosphere. Hence, statement 1 is not correct.The actions of exogenic forces result in wearing down (degradation) of relief/elevations and filling
up (aggradation) of basins/ depressions, on the earth‘s surface. The phenomenon of wearing down of
relief variations of the surface of the earth through erosion is known as gradation. The endogenic forces
continuously elevate or build up parts of the earth‘s surface and hence the exogenic processes fail to
even out the relief variations of the surface of the earth. Hence, statement 2 is not correct.IncorrectAnswer: D
