As the wind blows over the surface of still water, it creates friction that lifts some of the water away from the surface. In this way, sea currents are formed. If the amount of water displaced is very small, the surface tension pulls back the water to restore a smooth surface. If the amount of the wind is greater than small breeze then more friction is created and the surface becomes rougher and the frictional drag between water and air become greater.
Antidiuretic hormone stimulates water reabsorbtion by stimulating insertion of "water channels" or aquaporins into the membranes of kidney tubules. These channels transport solute-free water through tubular cells and back into blood, leading to a decrease in plasma osmolarity and an increase osmolarity of urine.
