What causes lunar eclipses?

Answer 1

A lunar eclipse occurs when the Moon passes through some part of the Earth's shadow. This only happens when the Earth, Moon and Sun are aligned. The Earth passes between the Sun and the Moon, casting its shadow on the Moon
A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow).
A lunar eclipse occurs when a satellite, usually a moon, moves so that the planet is between the sun and the satellite so that the planet blocks the light from the star from reaching the satellite.

Answer 2

The phase of the moon (new, half, full, etc) is a function of how much of its lit surface we can see from the earth. Half the moon is always sunlit, half is dark, but as the moon orbits the earth, more or less of the lit face is pointed towards us here on earth.

The moon's synodic period around the earth is about 29.5 days, which coincides with the length of a month. Once in each of its synodic periods, its lit face is directly oriented towards earth -- a full moon.

Because the synodic period is less than some calendar months, on relatively rare occasions we can have two full moons within one month. The second of those full moons is referred to as a "blue moon" -- thus the phrase, once in a blue moon, which means "rarely."

Answer 3

The maria? Maria is latin for "sea." These huge dark areas of the lunar surface were the result of massive ancient impacts, most likely, the energy from which caused molton rock to flow into the resulting basins. We suspect this because they are fairly round in shape, though overlapping.

Answer 4

The primary cause of lunar phases are the earth's revolutions.

Answer 5

By the Earth getting exactly between the Sun and the Moon.

Answer 6

The moon's revolution around the Earth (the Earth blocks the sun). That also creates a solar eclipse (except the moon blocks the sun).
