Tides and benefits for life

Of course all of us have often visited the beach or the sea, which is certainly a beautiful view of the sea isn't it? Among us all probably not many know that sea water can also experience the phenomenon of tides. Well, the tides are caused by the influence of the gravitational force of the moon and how does the tide occur? Look, we review a little, namely:
#Certainly salty sea water, sea water is also a liquid that easily changes shape when subjected to gravitational force. The shape of the sea surface can be different due to the influence of the gravity of the moon in a different place and on a different sea, either the broad ocean or the smaller strait. This results in an increase in sea levels |tides| and the presence of sea level |receding|. What is certain is that we generally know that the earth rotates, so in one day a place experiences twice the tide and twice receding.

Tides can be affected by the gravity of the moon or the gravity of the sun. But the gravity of the moon has a greater influence than the gravity of the sun because the distance of the moon is closer to the earth. The situation of high tide sea water occurs twice, namely during the full moon and the new moon. In the hemisphere that experiences a full moon, the distance of sea water to the center of the moon is closer than the center of the earth with the center of the moon.
#The same thing happens in the hemisphere that has experienced a new moon, the distance of sea water to the center of the moon is farther than the center of the earth with the center of the moon. This causes the moon's gravitational force to be stronger than the earth to attract sea water. Sea water becomes slightly higher against the surface of the earth, this is what is called tidal sea water.
So the question is when does the situation or condition of the sea water recede? This situation occurs in the hemisphere that does not experience than the full moon or the new moon or called the Perbani pairs [Indonesian language] Increasing sea levels in parts that experience the full moon or new moon certainly take than the quota of sea water from other hemispheres, therefore will cause other hemispheres to experience receding sea level. #When the situation is halfway through the month, receding sea water occurs more because the earth is located right in the middle between the parts that experience the full moon and the new moon.

The effect of the benefits of the phenomenon of tidal water is, it can be used as water transportation other than being used as a source of electric power, can be used as a hobby activity of water sports, can also be used for the manufacture of food salts and as a driving boat for fishermen, as a livelihood seashore. And also the effects of the tides can occur beautiful waves for Nature tourism.
