The Moon and Tides Observation

The line separating the illuminated part of the moon from the non-illuminated part is called the terminator of the moon. The phases of the moon change according to the position of the earth, the sun, the moon. The time required to return to the month of the month or to each stage of the cycle is 29.5 days (the month we are watching). The phases of the moon will gradually weaken the new moon, crescent moon, the first season, waxing, full moon, weakening, the third quarter (or the last moment), and the new moon and the new moon will gradually weaken. The new moon is the first stage of the month cycle.

When the moon is full or new, the moon and sun's attraction combine. At this time, the climax is very high and the low tide is very low. This is called a spring boom. The spring tide is particularly strong (it has nothing to do with the spring season). When the earth, the sun, the moon are lined up, they will happen. The gravity of the moon and the sun contribute to the tide. With a quarter of the moon, the sun and the moon work at right angles so that the bulges cancel each other. As a result, there is a slight difference between high tide and low tide, which is called small tide. The tidal low is especially tidal. They occur when the gravity of the moon and the sun are perpendicular to each other (with respect to the Earth). A tidal wave occurred during a quarter of the satellite

What is the low tide? When the tide range reaches the minimum, the interval between spring tide and low tide is 7 days. When the sun and the moon look at the earth from a right angle - between each new moon and the full moon - in the phases of the first quarter and last month - a small tide will occur. Then, when the moon is pulling the ocean, the gravity of the sun resists the gravity of the moon. Xiaochao occurs twice a month, once a month in the first quarter, once a month in the previous quarter.

What is some background tidal of spring? The sun, the earth and the moon are arranged more or less along the lines of the space around each new moon and full moon. And the gravity of the sun increases the gravity of the moon, so the tension of the tide rises. Indeed, the average solar tide is about 50% of the average monthly tide. Why does super moon draw a more extreme tide? If the new moon or full moon is closely aligned with the near point (the point closest to the Earth on the lunar orbit orbit), there is a super moon and an oversized spring tide. Some people call the spring tide of these surrounding areas. However, in recent years these nearly new or complete satellites are called super satellites, and some may be called super moon surges.
