How does the surface of continents and oceans affect the climate?

The proximity of the seas and the ocean is one of the most important factors in climate formation. Air masses are formed over the ocean, containing a large amount of water. Due to the constant circulation of the atmosphere, masses enter the mainland (due to the pressure difference). As it moves along the mainland, the air mass gives up part of its moisture. The further it moves inland, the less moisture remains in it and the central regions of the mainland do not receive it at all. The closer the territory is to the sea, the more likely it is to form a marine climate with a sufficient amount of precipitation.
