They align twice with the Earth.
Because the position of the moon, earth, and sun are not in the same exact place every month. This means they are a rare occurrence and only happen when the moon, earth and sun are in exact alignment with the earth.
No, spring tides do not only occur in spring. Spring tides happen twice a month, around the new moon and full moon, when the sun, moon, and Earth are aligned. This alignment causes the gravitational pull of the sun and moon to reinforce each other, creating higher than normal tides.
A solar eclipse is when the moon, momentarily blocks out the sun. It happens around once a month
The Moon, Sun and Earth are not perfectly aligned every month. Therefore there is not an eclipse every full Moon. The reason the alignment is usually not perfect is that the Moon's orbit is tilted relative to the plane of the Earth's orbit around the Sun.
Solar eclipses occur when the moon comes between the Earth and the Sun, but the moon's orbit is inclined by about 5 degrees to the Earth-sun plane. As a result, the moon's shadow usually misses the Earth during a new moon (when solar eclipses occur), hence they don't happen every month.
A full moon happens when the earth is between the sun and the moon, around the time in the month when the three bodies come as close to a straight line as they can get. The plane that contains the earth's orbit is not the same plane that contains the moon's orbit. So the sun, earth and moon cannot form a straight line every month during the full moon. If there were a straight line formed every month, then there would be an eclipse of the moon during every full moon. When a full moon happens at one of the two 'nodes', where the moon's orbit passes through the earth's orbital plane, there will also be an eclipse of the moon that month. So, strange as it may seem, there are slight variations on the actual 'fullness' of full moons from month to month.
The plane of the Moon's orbit is tilted to the ecliptic, which is the plane of the Earth's orbit. So 5 times out of six, the Moon is either above or below the direct line from the Earth to the Sun, and no eclipse happens.
My period. -_-
A full moon occurs about once every month when the moon is on the opposite side of the Earth from the sun, causing its face to be fully illuminated. This typically happens around the middle of the lunar cycle.
The moon takes one month to complete a revolution around the earth. A full moon occurs when the moon is on the opposite side of the earth from the sun (opposition). The full moon can only happen at this part of the lunar orbit, and it takes one month to complete the orbit; thus, full moon happens once a month.
That happens when the moon is out 'in front' of us, slightly closer to the sun than we are. When things are in that position and we look at the moon, we're looking at the 'back' of it ... the part that the sun isn't shining on ... so we see nothing.
We don't experience an eclipse every month because the Moon's orbit is tilted about 5 degrees relative to Earth's orbit around the Sun. This tilt means that the Sun, Earth, and Moon do not always align perfectly during the new moon (for solar eclipses) or full moon (for lunar eclipses). Eclipses only occur when the Sun, Earth, and Moon are in a straight line, which happens only a few times a year at specific points in their orbits called nodes. Therefore, while we have new and full moons every month, eclipses are much less frequent.
The full moon occurs whenever the moon orbits the earth opposite the sun. It takes the moon roughly 28 days to orbit the earth, so once every two weeks it is opposite the sun from us (full moon), and two weeks later it is on the same side as the sun and all we see is the moon's "night" side (new moon).
A full moon occurs when the Earth facing side of the moon is fully illuminated by the sun. Why? Because every month the Earth lies between the moon and the sun.
On average a full moon occurs every 29.53 days but it can be 29 days or 30 days hence the average.
Full moons occur approximately every 29.5 days, when the Moon is directly opposite the Sun in the sky, appearing as a complete circle. This happens because of the Moon's orbit around Earth.
