Answer:
Weight is a measure of gravitational pull.
Weight is a type of force which attracts things towards the center of earth. Weight is measured in Newton. Weight depends on the gravity of earth. Weight changes due to change in height. Value of gravity is higher at the center of earth and six times lower at the moon because of no gravitational force of earth.
New moon, quarter moon, full moon are what we call the lunar phases. These are consequences of the motions of the Sun, Earth and moon. Three dimensional models are useful because the face of the moon that catches the light of the Sun depending on their position at any given time could be depicted well. Circular models would be the best visuals for the lunar phases.
