The meaning of it is that the high tides are a little lower, and the low tides are a little higher than average. This results in the occurrence of high tides in the seas or the oceans.Īfter the seven days of spring tide, the moon and sun are at right angles to each other. During these events, the gravitational pull experienced by the Earth is very high because it experiences the pull from both the sun as well as from the moon. As we have studied earlier, Spring tides occur when there is a full moon or new moon. The most prominent effect of spring tide is on the tides that take place in the oceans or seas. It exerts a tidal force on the whole earth. The moon's pull is stronger than the sun.īecause it is much closer to the earth than the sun. The sun and moon both exert gravitational force on the earth. The greater gravitational force between the objects is close to each other. The moon's gravitational pull on the earth is the major tidal constituent. The forces that contribute to tides are called tidal constituents. The various reasons why spring tides occur are mentioned below: "It is a tide of the greater-than-average range around the times of new moon and full moon." - Merriam-Webster. The highest spring tides (equinoctial springs) occur at the equinoxes." Or "A spring tide is an unusually high tide that happens at the time of a new moon or a full moon." - Collins dictionary. "Either of the two tides that occur at or just after the new moon and full moon when the tide-generating force of the sun acts in the same direction as that of the moon, reinforcing it and causing the greatest rise and fall in tidal level. Some of the standard and recognised definitions are mentioned below: The term spring is derived from the concept of the tide "Springing forth". This tide occurs at a couple of inches to normal spring tides. It usually occurs three and four times in the year. This is popularly known as a "King Tide" which refers to the "springing forth" of the tide during a new and full moon. A tide that comes just after a new or full moon when there is a huge difference between high and low water. Due to the change of the tides, large quantities of water move towards or away from shore, causing tidal currents. It is caused by the gravitational pull of the moon and the sun. At the time of high tide, the sea is closer to the land, and at the low tide, it is farther away from, and more of the beach can be seen. Tides emerge in the sea and go towards the coastlines. Tides are the waves that occur through the regular change in the sea level caused by the moon and the sun. This topic will help you in Geography and Geology or Earth Sciences whenever you read about Oceanography. In this article, we will be talking about some of its types, such as spring and neap tides, the definition of spring tide or neap tide definition, perigean tide and all the related concepts. When these tides occur, the waves move towards the shores and affect the coastlines as well as the maritime activities of the nations. In oceans, the rise and fall of the water is a regular and common phenomenon. Can you imagine some gravitational pull of the Sun and the Moon can affect the natural world here on Earth? This phenomenon is known as a tide that occurs in the ocean.
