Sound waves are like waves in the ocean. when there is an earthquake under the water, the waves are created but, they do not move the water. This is because the water is acting as a medium for the energy produced by that earthquake. Because the energy stored in the sound wave needs particles to bounce off of the answer is D.

Before solving this question first we have to understand longitudinal wave and transverse wave.

A longitudinal wave is a wave in which the particles of the medium vibrate parallel to the direction of propagation of wave. In this type of wave one will notice compressions and rarefactions. Compressions are high pressure zones where the particles of the medium are close to each other . The rarefactions are low pressure zones where there will be large separation between particles.

A longitudinal wave is a repeated motion of compressions and rarefactions. The particle of the medium show a little displacement along the direction of wave.

A transverse wave is a wave in which the particle vibration is perpendicular to the direction of propagation of wave .In this type of wave one will notice crests and troughs.It is a repeated motion of crests and troughs.

Sound wave is a longitudinal wave. When it passes through air it forms rarefactions and compressions.

Hence from the above we get that out of the four options given in the question only option B is right which depicts that the air particles move parallel to the sound waves.

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
