Difference Between Neap Tide and Spring Tide

Neap Tide vs Spring Tide

A tide is the rise and fall of the larger bodies of water. It occurs because of the gravitational forces between the Earth, the sun, and the moon. The varying circulations of the current of the sea water cause it to be brought up onto a landmass. Places in the ocean can experience two high and low tides in each day called a semidiurnal tide. Other locations experience only one high tide and low tide called a diurnal tide. Characteristics of a tide change through different stages. When the sea level rises and covers the foreshore, known as a flood tide, and when the water reaches its highest point it is called a high tide or high water. After a period of time, the sea level recedes showing the intertidal zone again. This is called the ebb tide. And, finally, when the water stops falling back, the stage is called a low tide.

One of the earliest explanations of tides comes from Galileo Galilei. In 1632, he wrote a book named “Dialogue Concerning the Two Chief World Systems.” However, the theory was heavily disputed. It said that the movement of the Earth around the sun caused the tides. Johannes Kepler tried to correct the mistake by suggesting that the moon is the one causing the tides based on the idea of observations in the past. However, this was rejected by Galileo. The idea was corrected when Isaac Newton explained that tides are caused by the gravitational attraction of masses. In a book he published in 1687, named “The Principia,” he used his theory of universal gravitation to prove the phenomenon is caused by the lunar and solar attractions.

There are different kinds of tides depending on the alignment of the sun and moon. These two kinds are the neap tide and the spring tide. Spring tides occur on the new moon and the full moon. In this case, the gravitational attraction of the moon and sun is combined making it stronger. The high tides become higher than usual, and the low tides become very low. The alignment also causes an increased speed in tidal currents which also contributes to changes in the characteristics.

A neap tide occurs when the moon, the Earth, and the sun are at right angles. This causes the attraction to cancel each other and lessens the other affecting factors as well. The angles also cause the range high tide and the low tide to have minimal differences.

Summary:

1.A tide is the variation in the surface levels of the larger bodies of water. It is caused by the gravitational attraction of the sun, the moon, and the Earth. There are different stages of tides: high tide, flood tide, ebb tide, and low tide. The earliest explanation of the phenomenon came from Galileo Galilei, and the idea was corrected throughout the course of history.
2.There are also different kinds of tides that exist depending on the position of the sun, moon, and Earth. One is the neap tide which occurs when the three are at right angles, canceling the effects of one another and causing the stages of the tide to have smaller differences. The other, called a spring tide, happens when the three bodies are aligned. The effects stack up and result in a greater difference in the stages of the tides.
