HOW TO MAKE THE GRAPHIC ANIMATE?

• The four major moon phases are "New" , "1st Quarter" , "Full" and "Last or 3rd Quarter". These phases have to do with the relative positions of the sun, the moon and the earth in the moon's 29 day monthly orbit of the earth.
• The revolution of the Moon around the Earth makes the Moon appear as if it is changing shape in the sky. This is caused by the different angles from which we see the bright part of the Moon's surface. These are called "phases" of the Moon. Of course, the Moon doesn't generate any light itself; it just reflects the light of the Sun. The Moon passes through four major shapes during a cycle that repeats itself every 29.5 days. The phases always follow one another in the same order.
