The moon - the most close located to a star and fifth largest satellite of the Solar system. Distance between centers Earth and Moon on average about 384,467 km. To space measures this interval is very small therefore the planet and its satellite have considerable impact at each other.
What is inflows and otliva
The seas and oceans twice a day depart from the coast (outflow) and approach him (inflow) twice. On some reservoirs there are practically no inflows whereas on others the difference between an outflow and inflow on the coastline can make also up to 16 meters. Generally inflows are semidiurnal (twice a day), but in some places they daily allowance, that is, change of water level happens only once a day (one outflow and one inflow).
Inflows and otliva are most strongly noticeable in shores, but actually they pass on all thickness of oceans and other reservoirs. In passages and other bottlenecks of an otliva can reach very high speed – to 15 km/h. Generally on such phenomenon as inflows and otliva, the Moon influences, but somewhat the Sun also is involved in it. The moon is much closer to Earth, than the Sun therefore its influence on the World Ocean is even stronger than the planet in spite of the fact that the natural satellite much less, and both celestial bodies turn exactly around a star.
Influence of the Moon on inflows
If continents and islands did not prevent influence of the Moon on water, and all Earth's surface covered the ocean of equal depth, then inflows would look as follows. The site of the ocean, next to the Moon, at the expense of force of an attraction would rise towards to the natural satellite, at the expense of centrifugal force an opposite part of a reservoir would rise too, it will be inflow. Falling of water level would happen in the line which is perpendicular to a strip of influence of the Moon, in that part and there would be an outflow. The sun can have some impact on the World Ocean too. In a new moon and a full moon when the Moon and the Sun are located on one straight line with Earth, the attractive force of both stars develops, causing thereby the strongest inflows and otliva. If these celestial bodies are perpendicularly each other in relation to Earth, then two forces of an attraction will counteract each other, and inflows from otliva will be the weakest, but all the same in favor of the Moon. Existence of various islands and continents brings a big variety the movement of waters at otliva and inflows. On some reservoirs an important role is played by the course and natural obstacles in the form of sushi (islands) therefore water inflows and flows unevenly. Waters change the situation not only according to force of an attraction of the Moon, but also depending on a land relief. In this case at water level change it will begin to flow on a line of least resistance, but according to influence of a night star.
