Creative Writing: The Fall of Black Tide

Despite enjoying the luxury, he still despised them. When did Casey eat food in the kitchen in the square? "How are you?" She said with a voice and she moved from room to room to gather what was needed on that day. She soon came out of a big house and saw Cayce talking to a stable boy.

We live in a moment in the age of the universe. We humans come and go, and everything around us is usually the same. In the poem "Tide elevation, tide waterfall" by Henry Wadsworth Long Fellow, he wrote an article about the travelers who came to the coast, the tide slowly washed away footprints. This poem seems to be a simple work about a man on vacation, but in fact it has a deeper meaning and conveys more information. The poem began at the end of the sunset day, "travelers hurried to the town."

People living along the sea are accustomed to rising and falling daily tides. In the early years of history it was clear that the tide had to be relevant to the moon, as the daily delay of the high tide was the same as the daily lag of the rising of the moon. But a satisfactory explanation for the tide is waiting for the gravity theory provided by Newton. The gravity that the moon exerts at several points on the earth is shown in Figure 1. These forces are slightly different from each other because the earth is not a point, but it has a certain size: all parts are not equal to the moon, and they are not exactly the same direction as the moon. Furthermore, the earth is not completely rigid. As a result, the earth is slightly warped by the difference in attraction of the moon (called differential dynamics) at various places on the earth.

The tsunami is a periodic increase and decrease in large water areas. Wind and water flow to the surface water, causing waves. The gravity of the moon inflates the sea in the direction of the moon. The other bulge also occurs on the other side. The earth will also be pulled towards the moon (and away from the distant water). Due to the interaction of the sun, the moon and the earth, the sea level varies every day. When the moon orbits the earth, when they go round the sun, gravity may combine and the sea of ​​the world may go up and down. At this time the earth is rotating, so twice everyday tides occur.
