Why doesn't a solar eclipse occur during each full moon?
In the first place, solar eclipses happen at New Moon. Apart from that, the Moon has an orbit that is inclined to the plane of the Earth's orbit, and an eclipse can only occur when it is crossing that plane. If it is not, the Moon passes above or below the Sun and there is no eclipse.
What we commonly call a solar eclipse can occur ONLY at the time of the new moon. In order for the solar eclipse to occur, one of the nodes of the lunar orbit must be aligned with the sun at the time of new moon; hence, a solar eclipse doesn't occur at every new moon. Solar eclipse can only happen at new moon.
High tides occur during Solar Eclipse, moderately high tide occur during Lunar Eclipse and Low Tide occur during Quarter Moon.. More Basic information... Tide - rise and fall of ocean water due to the gravitation, location and distance of sun, moon and earth... "Best Friends Listen to what you don't say" -Samantha Norman Hope I can help :)
Why does a lunar eclipse occur when there is a full moon and a solar eclipse occur when there is a new moon?
Tides are affected by both the moon and the sun. Each month the highest high tides occur when the moon and sun are in rough alignment and thus "pulling" together on the oceans. During a solar eclipse the alignment of sun and moon are not significantly different from what we get during other months when the highest monthly tides occur without an eclipse.
