The cause of wind, tide and sea currents

Wind, tides and sea currents are all natural phenomena commonly seen on Earth. But where do they come from, not everyone knows, everyone remembers. So let's find out where the wind, tide and sea come from!

The cause of the wind

Wind is a phenomenon in nature formed by the movement of air on a large scale.

Wind is a phenomenon in nature formed by the movement of air on a large scale. The air always moves from where the air is high to where the pressure is low. This movement of air generates wind.

The cause of the tide

The tide is the phenomenon of sea water, river water . up and down in a period of time dependent on astronomical changes. The gravitational change from the Moon (the main part) and from other celestial bodies such as the Sun (small part) at any point on the Earth's surface while the Earth rotates creates a phenomenon of rising water ( high tide) and sprinting (ebb tide) at certain times in a day.

The cause of the tide is due to the flattened spherical hydrograph but is pulled up in two opposite regions forming the ellipsoid shape. A peak of the ellipsoid directly opposite the Moon is the first large water domain, caused by the gravitational force of the Moon. The second largest water area is opposite the first large water body through the center of the Earth, created by centrifugal force.

The tide is the phenomenon of sea water, river water . up and down in a period of time dependent on astronomical changes.

Between the two big countries is net. Once the angular velocity (rotation speed) of the Earth remains constant, the largest centrifugal force lies in the place where the maximum turning radius is that of the Earth's equatorial region. However, the turning radius is not necessarily the radius of the Earth at the Equator, because: The Earth does not completely rotate around its axis, nor does the Moon completely revolve around the Earth, but: The Earthly System - The moon revolves around the central point of this system. Because the Earth's mass is much larger than that of the Moon, the focus of the Earth-Moon system lies in the Earth's heart, on the path connecting their center. In short: The Earth has just turned and shook.

Causes of sea currents

Water blocks in the seas and oceans are always moving. One of the forms of movement is the phenomenon of flowing streams like the rivers on the continent.These flows are collectively referred to as ocean currents or ocean currents. For large currents in the oceans, they are called positive deposits .

Regarding the cause of sea currents, scientists have affirmed that: the regular wind system of atmospheric circulation (such as Tin phong, temperate West wind, polar east wind, monsoon) is the driving force weak cause of flow in the sea and ocean.

Other factors such as the difference between seawater temperature at different latitudes, concentration of dissolved salts, etc. are also influential, but not significant.
