Earth is different from all the planets in the solar system. About 70% of it is submerged. At such places where the sea meets the ground floor, the sea water keeps descending regularly there.
The action of landing on the ground floor of sea water regularly is called tide ebb. The process of climbing over water is called tide and the process of coming down. Sometimes this tide ebb comes at a very rapid pace and affects the coastal areas.
What is Tides and Why it comes –
The main reason for the ebb and ebb of the earth is the moon and the sun. If a deep study is done, then it will be known that the gravity of the sun and moon are responsible for this.
That is, the moon and the sun have a role in the arrival of tide ebb. It is important to note that the moon draws that part more towards it than the central part of the earth.
Because of this, this part of the Earth rises slightly towards the moon. In the same way, the moon again pulls the middle part more towards it than the distant part of the earth.
Due to this, the distant part of the earth emerges outwards. Actually, this emergence is the emergence of part of the sea.
In this way one part of the sea rises towards Chand and another part emerges away from Chand. When the moon revolves around the earth and the earth is that of the sun, at this time the level of sea water rises and decreases. Because of this, tide ebb is born.
Tide types –
Tides can be divided into two types. It can be known by different names according to the height and the moon.
- By height –
- Long tide: The time when the tide water attains the highest height at the time of tide cycle, it is called the high tide.
- Short tide : The water level that remains at the time of tide cycle is called low tide.
- By location –
Depending on the location of the moon, there can be two types of tides.
- Spring Tide: At the time of Amavasya or full moon and new moon, the moon and sun come in a line, at that time a very high gravity of gravity is produced, which is called Spring Tide.
- Neap tide: The time when the moon and the sun are not in the same line, that is, they form a right angle in the center of the earth. At that time the value of this gravity is very low, and tidal ebb is not very strong. It is called neap tide.
In addition to the above tide, the tide can also be defined in other ways, the details of which are given below.
- Daily tide (dural tide): It happens daily. It occurs at some place on the earth when the moon is away from the equator. This tide is commonly seen in the Gulf of Mexico.
- Semi-daily tide (Semi dural tide) : Semi dural tide comes four times a day, which consists of 2 long tides and 2 short tides. The point to note is that the height of the second high tide is equal to the height of the first high tide. Such tides come when the moon shines directly on the equator.
- Mixed tide : Mixed tide also has two long tides and two short tides. However, the height of long tides is not equal. Therefore, the height of any tide is not equal to any other tide. Mixed tide often occurs when the moon is north or south from the equator.
- Metrological Tides : All the above types of tides are due to the force of gravity only, but there are also tides, which also depend on other natural factors. This includes air pressure, rain, glacier melting etc. Such a tide is called metrological tide.
- Anaerobic and equatorial linear tides : When the Moon’s inclination is perpendicular to the Tropic of Cancer, the tides that are produced at that time are called the tidal waves. Their height is not the same. At which time the inclination of the moon falls on the equator or equator. So the tides generated at that time are called equatorial tides. Their condition is not the same.
South Hampton Tide
Jowar reflux usually occurs about twice a day. But South Hampton, located on the southern coast of England, has four times a day tide.
The biggest reason for this is that South Hampton is connected by two seas, one is the English Channel and the other is the North Sea, there are two tides from these two seas.
Therefore, due to tides due to English Channel twice and North Sea twice, tides come here 4 times a day.
Tide related facts –
It is a very important thing to know about jowar reflux, because many types of competitions ask questions related to it. Here are some special things related to it,
- Elevated water waves are generated at the time of tide, this is called tidal wave. Such waves occur twice every 24 hours in a tidal ebb of the oceans.
- The attraction power of the Sun is less than the attraction power of the Moon, less than about 2½ times.
- Note that on the full moon and Amavasya, there is a high tide in the oceans, because on this day the earth moon and sun live in a straight line. On this day, the high tide comes twice in 24 hours and 52 minutes.
- There is an interval of 12 hours 26 minutes in the arrival of two tides.
- Short tides are 20% lower than normal tides.
- The highest tide in the world comes in the Bay of Fundy.
Importance of Tidal Energy in Human Life –
Like other natural phenomena, tides have a great importance in human life. It has some special advantages, which are described below.
- Jowar is being used in the field of generating energy these days. With its help, a high amount of energy can be prepared, which is useful in various fields.
- The tide of the sea is completely cleared by the tide.
- With this help, navigation is facilitated in any sea. Due to this, the depth of any sea remains intact and the ships can swim easily.
- With its help, electricity is prepared in many places.
- Due to the tide, there is continuity in the flow of the sea and the sea does not freeze.
- Due to the tides, there is lavishness in the sea, that is, the salinity of the sea water remains intact.
In this way, people get many benefits from the tide.
