why tides are high duruing full moon and new moon day?
Answers
Answer:
Explanation:
As far as I've known, sea tides are higher on a Full moon day. And that is due to the "gravitational pull" of the moon. But we know that moon is visible because of reflection of sun's rays. So, even on a new moon's day, the moon is still there, but it's not visible.
Answer:
There are two main gravitational causes of tides: the Moon, and to a lesser extent the Sun.
When the moon is full or the moon is new, the Earth, Moon and Sun are roughly aligned, and the Lunar tide combines with the Solar tide to give a "Spring tide" that has a larger range.
When the moon is at first quarter, or third quarter (i.e a half moon), the solar tide and the lunar tide are acting against each other, and you get a "neap tide" with a lower range than a spring tide.
The size of the tide on a particular day at a particular location is strongly affected by the local shape of the coast and sea floor, Some places only have one tide each day, or tides of different size, due to these effects.
Note the name "Spring tide" is not from the season. You get Spring tides every New and every Full moon. It comes from an old English word meaning "to bulge". The tide "bulges" during New and Full moon.
