S1: The real cause for the rise and fall of the sea level was not known to men for a long time.
P: They found out that the Moon is a satellite and it travels a regular path around the Earth.
Q: As time passed and knowledge increased, men began to learn more about the heaven and the stars and the planets.
R: They noticed that the Moon rose each day about an hour later than it rose the day before and the peak of the high tide also comes about an hour later each day.
S: Some imagined that the Earth itself was alive and the rising and falling of the tide was caused by the breathing of the Earth's big body.
S6: So they concluded that the Moon and the tide are connected in some way.
