The Lunar cycle takes 28 days. That's how long it takes to go from one full moon round to the next.
no it always changes
the reason you only see one side of the moon is because the rotation of the moon and the revolution speed of the moon are the same
The moon looks the same where ever it can be seen at a given time.
It doesn't
The moon is always a sphere but the moon does not look the same every week when observed from Earth. This is because we see sunlight hitting the moon at different angles as it orbits our planet.
Yes you muppet
Yes. Everyone on earth for whom the moon is visible sees the same phase at the same time.
Because the moon takes the same time to rotate once on its axis - as it does to go around the earth. Therefore we see the same side of the moon every time.
the same
The answer to that truthfully is: "Mere coincidence".
lol because
The same as usual
