A lunar eclipse can only occur during a full moon because the lunar eclipse causes the Moon to pass directly behind the Earth and into its shadow. This can occur only when the Sun, Earth, and Moon are aligned exactly, or very closely with the Earth in the middle.
The phases of the moon, whether full, half, gibbous, or new, depend upon the relative positions of three things: the sun, the moon, and the person who is observing the moon. There is always one half of the moon being fully illuminated by the sun, just as there is always half of the Earth being illuminated by the sun (not counting eclipses). If you happen to be positioned where you can see the whole illuminated half of the moon, then the moon appears as a full moon.
the gravitation of the moon is greater and the tides can either become bigger or smaller
During a full lunar eclipse, the visible half of the moon's surface is in the Earth's shadow while the rest does not receive sunlight because it is facing away from the Sun. Lunar eclipses occur during full moon phases.
High tides are the biggest when the moon is Full or when the moon is a New Moon. The gravitational pull of the Moon is greatest at these phases which makes a bigger bulge in the ocean causing high tide. But it also depends on the time of year when the tides are low or high.
About 2. The lunar tidal cycle is 12 hours & 25 min. (Note that not all tides are lunar.)
Several problems can and do occur during such periods.Lack of communication, such as roads. Lack of amenities, schools, public libraries etc. Lack of services and utilities, gas, electricity, water, sewage, etc..

No, it cannot. Lunar eclipses (they really aren't even true eclipses) can happen only during full moon.
yes
Lunar eclipses always occur at the full moon, while solar eclipses can only happen during a new moon. thats a horrible answer , you could get that from watching twilight once.
No. About 50% of all lunar eclipses are total; the remainder are partial or penumbral.
Lunar eclipses occur precisely at the full moon.
Solar eclipses happen during NEW moons, when the Moon blocks the light of the Sun. Lunar eclipses happen during FULL moons, when the Earth blocks the light of the Sun.
Every year
Yes.
Yes
Solar eclipses occur when the Moon is in the direct path between the Sun and Earth. Lunar eclipses occur when the Earth is in the direct path between the Sun and the Moon.
No. During the 20th Century, they averaged about 2.3 per year.
Lunar eclipses can only occur at the full moon.
