Why is the water near the equator clear and translucent, and the water far from the equator not tran

In order to explain this problem, we need to consider some factors that affect the transparency of seawater, including suspended matter, nutrients in the water body, plankton in the water body, circulation and mixing of the water body, etc.

First, the water near the equator is generally clearer than far from the equator, mainly because the water in the equatorial region flows faster, resulting in less suspended matter and plankton in the water column, which makes the water clearer and clearer.

Secondly, the nutrients in the water body can also affect the transparency of the seawater. The more nutrients there are, the more phytoplankton and zooplankton grow in the seawater, and these organisms consume oxygen in the water, making the water turbid. As a result, it is easier for the sea to remain clear in places with fewer nutrients.

Finally, the circulation and mixing of water bodies can also affect the transparency of seawater. In places where there is less circulation and mixing, suspended matter and plankton in the water body are more likely to settle, making the water body clearer. In places where circulation and mixing are strong, suspended matter and plankton in the water body are more likely to be stirred, making the water body more turbid.

In summary, the reasons why the sea water near the equator is clear and translucent and the sea water far from the equator is impermeable are multifaceted, including the flow of water bodies, nutrients, circulation and mixing.

About tides: Tidal phenomena are a natural phenomenon in coastal areas that refers to the gravitational force of sea water by celestial bodies, mainly the Moon and the Sun.

The density of seawater varies with changes in salinity, temperature, pressure, and when the temperature decreases, the salinity increases, or the pressure increases, the density of seawater increases. Seawater is denser than freshwater; The density of seawater varies little with time and space. The density of seawater is high, and the buoyancy is also large, and it is not easy to sink in seawater than in freshwater; Antarctica is cold, salinity is high, and sea water is dense.

The temperature, salinity, and pressure of seawater are all related to the density of seawater. The effect of temperature and salinity on density is that when the temperature is the same, the higher the salinity, the greater the density; With the same salinity, the higher the temperature, the less dense it is. But in general, the salinity of seawater does not vary much horizontally or vertically, so seawater temperature is the main factor affecting seawater density.

Because of the high precipitation in the equatorial region, the salinity is lower than that in the subtropical sea, so the temperature and salinity of the ocean surface near the equator compared with the adjacent sea area are high and salinity is low. In Antarctica, the sea temperature is extremely low, so it is dense.

Warm currents pass through and precipitation is high in equatorial regions.
