    2Thank You

    Weathering involves disintegration or decay of solid rock due to change in temperature and weather and their impact on the composition of rock.

    Weathering may be :

    1. Mechanical : weathering is the disintegration of rocks by mechanical forces, without chemical changes.
    2. Chemical : weathering is the gradual decomposition of the rock owing to the reaction and combination of the constituent minerals of the rock with oxygen or carbon dioxide present in the atmosphere. In Chemical weathering the presence of water is essential.

    Characteristics of a Sound Wave:

    A sound wave is described by the following characteristics:

    i. Frequency: The  number  of  complete  oscillations  per  second  is  called  the frequency (ν)  of  the  sound  wave.  The unit of frequency is hertz (Hz).

    ii. Amplitude: The  magnitude  of  maximum  disturbance  in  the  medium  on  either  side  of  the  mean  position  is  called the amplitude (A). The amplitude of a wave is the same as the amplitude of the vibrating body producing the wave. The loudness or softness of a sound is determined basically by its amplitude which depends upon the force with which an object is made to vibrate.

    iii. Speed: The distance travelled by a wave in one second is called the velocity or speed of the wave.
