Physical Features: Phases of the Moon

• P1 - Time for the Moon to orbit around the Earth once

• P2 - Direction of the Moon’s rotation around the Moon

• P3 - Time for the Moon to complete its cycle of phases.

• P4 - Cause of Phases

• P5 - General Direction of the Moon’s rising

• P6 - Change in phase over time

• P7 - Phase and Sun-Earth-Moon positions

• P8 - Phase - location in sky - time of observation relationship

• P9 - Effect on Moon phase with Change in location on Earth
