Write a brief note on Neap Tide.

When the Sun, Earth and Moon are not in a straight line, the Sun and Moon are not exerting combined force, i.e., they are not ‘pulling’ together and the gravitational pull is much less. At half moon, that is, when the Sun and Moon are ‘pulling’ at right angles, the force exerted is at its least and the difference between high and low tide is not large. These tides are called Neap Tides.
