Sun affects ocean currents

Sun affects ocean currents. The sun heats the atmosphere creating winds and movement in the sea surface through friction Wind blows hard that cause movement in the water surface creating ocean currents. Sun alters density of the ocean surface water by changing its temperature and its salinity

BLIZZARD

BLIZZARD. What is blizzard?. A blizzard is a storm which is a combination of wind and blowing snow resulting in low visibility. It is a lot stronger than a snowstorm and can sometimes happen when it is not snowing, as the wind picks up snow from other areas. Low Visibility. Strong winds.
