Question

Укажите главную причину возникновения поверхностных океанических течений А) постоянные ветры Б) различия в плотности воды В) различия в химическом составе воды Г) вращение Земли вокруг Солнца

Answer 1

Вращение земли вокруг солнца

Answer 2

The main cause of the formation of surface ocean currents is A) constant winds. The wind exerts a force on the surface layer of water, causing it to move in the direction of the wind. The water also deflects to the right or left due to the Coriolis effect, which is caused by the rotation of the Earth. The Coriolis effect is stronger at higher latitudes, so the water moves more perpendicular to the wind direction near the poles than near the equator.

The other factors, such as B) differences in water density, C) differences in water chemical composition, and D) rotation of the Earth around the Sun, have less influence on the surface currents. Differences in water density and chemical composition can create vertical currents that move water up or down in the ocean, but they do not affect the horizontal movement of water much. The rotation of the Earth around the Sun affects the seasonal changes in the ocean temperature and salinity, which can alter the density and pressure gradients of water, but it does not directly cause the surface currents.
