asthenosphere and convection

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
