The currents are generated from the forces acting upon the water like the earth's rotation, the wind, the temperature and salinity differences and the gravitation of the moon.The depth contours, the shoreline and other currents influence the current's direction and strength Ocean currents can flow for thousands of kilometers.They are very important in determining the climates of the continents, especially those regions bordering on the ocean.Ocean currents can be generated by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes.
During the day,the land heats faster than the sea.The air over the land rises.Cooler air from the sea blows towards the land to replace the rising air.The cool air from the sea becomes the sea breeze.In the daytime, the land heats up quicker than the water,this causes the warmer air to rise resulting in a slight decrease of air pressure overland. the cooler air over the ocean moves inland (sea breeze). At night just the reverse happens because the land cools more rapidly than the water,thus you get a land breeze towards the ocean.
2) continents heat up faster than the oceans, and they cool down faster too. It’s why London has an average January low temperature of 2C while Winnipeg's is closer to -20C, even though they’re at almost the same latitude. There are a few reasons for the land-ocean cooling differences, and they all have to do with how heat is absorbed and transported.
(1) Specific Heat Capacity. Water has a higher heat capacity than land. So it takes more heat to raise the temperature of one gram of water by one degree than it does to raise the temperature of land. 1 calorie of solar energy (any type of energy really) will warm one gram of water by 1 degree Celcius, while the same calorie would raise the temperature of a gram of granite by more than 5 degrees C. The Engineering Toolbox has specific heat capacities of common materials.
(2) Transparency. The heat absorbed by the ocean is spread out over a greater volume because the oceans are transparent (to some degree). Since light can penetrate the surface of the water the heat from the sun is dispersed over a greater depth.
(3) Evaporation. The oceans loose a lot of heat from evaporation. In the evaporative heat loss experiment, While there is some evaporation from wet soils and transpiration by plants, the land does not have anywhere near as much available moisture to cool it down.
(4) Currents. Not only do the oceans absorb heat over a greater depth, but they can also move that energy around with their currents. The solar energy absorbed at the equator gets transported towards the poles, while the colder polar water gets transported the other way. Currents help average out ocean temperatures.
