How do surface currents develop?

Answer 1

Deep ocean currents are caused by 3 things:

• change in temperature
• change in salinity by evaporation
• change in salinity by freezing

Because colder water and saltier water are more dense, they sink, and the motion causes deep currents.

Answer 2

Global winds drag on the water's surface, causing it to move and build up in the direction that the wind is blowing. And just as the Coriolis effect deflects winds to the right in the Northern Hemisphere and to the left in the Southern Hemisphere, it also results in the deflection of major surface ocean currents to the right in the Northern Hemisphere (in a clockwise spiral) and to the left in the Southern Hemisphere (in a counter-clockwise spiral). These major spirals of ocean-circling currents are called "gyres" and occur north and south of the equator. They do not occur at the equator, where the Coriolis effect is not present.

Answer 3

Surface currents develop primarily due to the combination of wind, Earth's rotation (Coriolis effect), and differences in water temperature and salinity. Winds blowing across the ocean surface generate friction, causing the water to move in the direction of the wind. The Coriolis effect then deflects this movement, leading to the formation of large-scale circulating currents.

Answer 4

of course i can answer this question... what am i stupid?

haha yeah i have no idea

Answer 5

surface currents develop from friction between the ocean and wind that blow across its surface.
