The moon is a major influence on the Earth’s tides, but the sun also generates considerable tidal forces. Solar tides are about half as large as lunar tides and are expressed as a variation of lunar tidal patterns, not as a separate set of tides. When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides—both commonly called spring tides. One week later, when the sun and moon are at right angles to each other, the solar tide partially cancels out the lunar tide and produces moderate tides known as neap tides. During each lunar month, two sets of spring tides and two sets of neap tides occur (Sumich, J.L., 1996).

Music has become a very dense part of the life of a modern person. She surrounds us everywhere: in the store, in the subway, and just on the street you can hear her motives. We are so accustomed to it that sometimes it not only coincides with our mood, but also makes it. It's hard for me to say what kind of music I like. But of course I give preference to rock, such songs, in my opinion, are filled with deep meaning and emotions. My favorite is folk-rock, each song is a little story about love, about life. When, after a hard day, I just want to be alone a little, I listen to classical music. It will penetrate the very soul, thus awakening in it an endless thirst for life.
