Group S Phases Of The Moon

Phases Of The Moon

The Moon the Moon was probably made 4.5 billion years ago when a large object hit the Earth and blasted out rocks that came together to orbit round the Earth. They eventually melted
together,cooled down and became the Moon. For another 500 million years pieces of rock kept striking aginst the surface of the Moon.

The phases are named after how much of the moon we can see, and whether the amount visible is increasing, or decreasing each day.

People in different hemispheres see the moon in a slightly different way.
In the Southern Hemisphere, people see the moon 'upside down' so the side which is shining (sunlit) seems the opposite from the Northern Hemisphere.

Countries in the different hemispheres see the Moon from a completely different vantage point from each other.
In the northern hemisphere the first quarter looks like a growing D, while in the southern hemisphere it looks like a C.
In the northern hemisphere the last quarter looks like a C, while in the southern hemisphere looks like a D.

What causes the different phases of the Moon?

The phases of the Moon depend on its position in relation to the Sun and Earth. As the Moon makes its way around the Earth, we see the bright parts of the Moon's surface at different angles. These are called "phases" of the Moon.
