The importance of tides is immense in human life and other areas. The number of fish in the river increased due to low tides. The tidal waves can be controlled to create a higher force as compared to wind energy. generate link and share the link here. There has been a constant focus on developing renewable energy resources to avoid over-consumption of non-renewable resources. Many marine fish move into the river during high tide. Thus, it is the moons gravitational force that pulls the ocean towards itself, causing a high tide. The large continents on the planet, however, block the westward passage of the tidal bulges as the Earth rotates. spits etc. The tides help to create low floodplains of rivers. o Tides influence salt and fresh water mixing in estuaries. Fishing The high tides also help in fishing. A wave has two major parts: the raised part is called as the crest while the low-point is called as the trough. Important Geophysical phenomena such as earthquakes, tsunamis, Volcanic activity, cyclones, etc., geographical features and their location- changes in critical geographical features (including water bodies and ice-caps) and in flora and fauna and the effects of such changes. The influence of spring tide on human life is greater than the neap tide. Creeks and inlet formation are caused by tides. When a tide enters the narrow and shallow estuary of a river, the front of the tidal wave appears to be vertical owing to the piling up of water of the river against the tidal wave and the friction of the river bed. Rise and fall of the oceans water level because of the gravitational forces of the sun and the moon are referred to as Tides. It is free to move all over the earth. Through the tide the freshwater of the river becomes salty. The successive high and low tides are approximately of the same height. Every 24 hours, there are two high tides and two low tides. This phenomenon occurs due to the centrifugal force of the earth and the gravitational force of the moon and the sun. Tides can play an important role in the mitigation of pollution in water. Many more fish come closer to the shore during the high tide. These types of tides are strong tides. Tides are the rise and fall of sea water caused by the sun and moon's gravitational influences. Tides are one of the most important geographical phenomena that are happening frequently in water bodies on earth. Neap tides happen during quarter moons when tides are weakest). Therefore most of the time tides occur in the ocean. Today its Indias top website and an institution when it comes to imparting quality content, guidance and teaching for IAS Exam. Tides are very important in controlling the depth and flow of water to help ships navigate easily near the shores. Strong tidal bores disrupt fishing zones in estuaries and gulfs. There are different types of it, such as spring tides, neap tides, high tides, and low tides. Like spring tides, these tides also occur, Once in a month, when the moons orbit is closest to the earth, Two weeks later, when the moon is farthest from earth, Tidal heights are very important, especially harbours near rivers and within estuaries having shallow.

These powerful water movements are leveraged for generating electricity that can be catered to meet energy needs in different parts of the world. Tides can be defined as the alternate rise and fall of the ocean water. These are very fertile. For the UPSC examination you have to know all the tribes and what are their . The effects of neap tide on human life are less. Tides are used to generate electrical power (in Canada, France, Russia, and China). Due to the gravitational force of the moon, the seawater swells up and down at regular intervals. There is only one high tide and one low tide during each day. Tidal energy: One of the most significant importance of tides is producing tidal energy. InsightsIAS Headquarters, Always try to link the subject matter of Paper 1 and Paper 2. As a result of the tide, the river bed becomes deep. Tidal bores affect the river mouths ecology as well. The article below briefs the Formation of Tides followed by detailed explanations which is useful for UPSC Geography Syllabus. Tides are long waves that move across the ocean which is one large body of water. Tide changes proceed via the following stages: Tides vary in their frequency, direction and movement from place to place and also from time to time. Scientific studies have revealed facts about the nature and intensity of tides that can be used most effectively for the benefit of modern civilization. They bring saltwater to the shore and their constant movement prevents the port from freezing. London and Calcutta[Tidal Ports] have become important ports owing to the tidal nature of the mouths of the Thames and Hooghly respectively.

Animals can get hit by the leading edge of the tidal wave and might lose their lives in the rush of the silty water. The tidal-bore affected estuaries are the rich feeding zones and breeding grounds of several forms of wildlife. It is covered in both the General Studies paper in the UPSC Prelims and the GS Paper 1 in the UPSC (Main) examination. Tides generally help in making some of the rivers navigable for ocean-going vessels. During high tide, the level of water goes up generating long waves that move across the shores. The gravitational pull causes the rise and fall of the water surface in oceans that happens at a periodic interval according to the rotation of the earth. Ports and rivers are often ice-free in tidal saltwater. Tides Tide are the periodical rise and fall of the sea levels, once or twice a day, caused by the combined effects of the gravitational forces exerted by the sun, the moon and the rotation of the earth. This is called secondary tide. The occurrence of tides is generally observed in large water bodies like seas and oceans due to their vastness and spread and to a small extent in small water bodies like rivers and lakes. When it comes to the Mains exam, PYQs become even more important. It is caused by the combined effects of : Tides occur due to a balance between all these forces.

London and Calcutta [Tidal Ports] have become important ports owing to the tidal nature of the mouths of the Thames and Hooghly respectively. The river must be shallow and have a narrow outlet towards the sea for a tidal bore to occur. Many more fish come closer to the shore during the high tide. Flood plains are very fertile. Rogue waves are very high and limited in area; When the highest part, or crest, of the wave, reaches a particular location, high tide occurs; low tide corresponds to the lowest part of the wave, or its trough. Spring Tides are the result of the sun and moon working together to exert more pull on the earths oceans. This causes the moon and the sun to attract the earth from opposite directions. Due to experiencing high and low tides, some plants and animals are adapted to live both inside and outside water in such regions. Tidal bores of considerable magnitude can capsize boats and ships of considerable size. When the channel becomes deeper, it is seen as a positive surge. This helps the navigators and fishermen plan their activities. As a result, the water in the opposite place also swells, that is, the tide is created. Electricity can be generated by exploiting the huge energy potential of the tides. Energy of tides is much more than the rogue waves or storm breakers. Tides may be grouped into various types based on their frequency of occurrence in one day or 24 hours or based on their height. A Spring tide occurs on a full moon or new moon days.
