The moon rotates around the Earth and makes one round about 28-32 days. During this time it changes its form many times.
The moon has mane shapes, for example it can be a thin moon or full moon. This is called the phases of moon. The phase of moon is a satellite illumination of the sunlight which changes periodically.

12 times a year the moon is perfectly round and glowing in the night sky.
This is called a FULL MOON.
10 слайд
People can always see the moon in the night sky in all its forms because the sunlight falls on the moon and is reflected from its surface.
11 слайд
But 3-4 times a year the moon in the Full Moon becomes dark red.
This is called a LUNAR ECLIPSE.
12 слайд
This happens when the Sun, the Earth and the Moon stand in one line.
And the orbit motion of the Moon and the Earth coincide at this point.
At this moment, the Earth is covering the moon from the Sun by its shadow as more of the moon 4 times.
A Lunar Eclipse lasts about 108 minutes.
