Study Notes
Lunar Cycle and Phases of the Moon
- The Moon moves completely around Earth in a four-week lunar cycle.
- The amount of the Moon's face illuminated by sunlight depends on the angle the Sun makes with the Moon.
Phases of the Moon
- The position labeled 'New' in the image represents the side of the Moon facing away from the Sun, resulting in no illumination.
- The position labeled 'Full' in the image represents the entire face of the Moon illuminated by sunlight.
Relationship Between Sun and Moon
- The Sun's movement affects the phases of the Moon, as the changing angle of the Sun with the Moon alters the amount of illumination.
- The Sun's movement is not directly related to the Moon's movement around Earth.
Sun's Movement
- The Sun does not move 1/12 of its path around the sky each day.
Moon's Illumination
- The amount of the Moon's face illuminated by sunlight depends on the angle the Sun makes with the Moon, not the angle the Earth makes with the Moon.
