How do waves change as they approach the shore?

Option B, The distance between crests decreases

Explanation:

Complete question is

How do waves change as they approach the shore?

A. The height of the waves decreases B. The distance between crests decreases C. Friction acting on the top of the wave increases D. The wavelength increases

Solution -

When the wave approaches the shore, land provides resistance to wave from the bottom as well as from the sides. Due to this resistance, the speed of the wave reduces and it starts slowing as it approaches the shore. The waves start breaking and hence its wavelength reduces and the distance between the crest as well as its height also reduces.  

Hence, option B is correct

the cytokine-activated janus kinase (jak)-signal transducer and activator of transcription (stat) pathway has an important role in the control of immune responses. dysregulation of jak-stat signaling is associated with various immune disorders.
