1.)The regular rise and fall in the level of the ocean water is called tide.Tides are the chief and the most observable effect of the moon's gravitational pull on the earth.
On the side of the earth where the moon is, the gravity of the moon causes a bulge to occur on the solid part of the earth.The bulge is only about few inches atmost,but because the water in the ocean is free to move,it behaves as of it is pulled away from the earth.
2.)Twice each month,that i, during full moon and new moon,high tides and low tides are respectively higher and lower that usual.At sich times,the sun,the moon, and the earth are in line with each othernThe gravitational pull of the sun,althrough weaker (only about 7 percent) because of its great distance,coordinates with the gravity of the moon.Tides produced in the case are called springtides.
3.)Twice a month also, the high tide are lower that usual and the low tides are higher that usual.This happens when the sun,moon, and thw earth are at rigth angles with each other (during the first and last phases).The gravitational pull pf the sun and the moon seems to cancel each other.The tides produced in this case are called neaptides.
Rather, the term is derived from the concept of the tide "springing forth." Spring tides occur twice each lunar month all year long without regard to the season. Neap tides, which also occur twice a month, happen when the sun and moon are at right angles to each other.
