Question

questions: please use complete sentences. (points will be deducted for incomplete sentences.)1. describe the process that causes the moon to appear as different phases.____the moon appears in different phases because of therelative __________(size or positions) of the earth, moon, andsun. the sun shines on the moon and we see__________________(the same or different) portions of themoon from earth.2. how long does it take the moon to go through one full cycle of phases (use your book as needed)?it takes about ________(27.3 or 29.5) days for the moon to gothrough one full cycle of phases.3. why do we always see the same side of the moon from earth? be sure to explain how the moon is moving through space.for every ____________(rotation or revolution) the moonmakes around the earth, it completes one__________(rotation or revolution) on its axis.4. the moon and earth both rotate and revolve. describe the difference between rotation and revolution.the moon ____________(revolves or rotates) on its axis(spinning motion) and ____________(revolves or rotates)around the earth.

Explanation:

1. Moon phases form because the changing positions of Earth, Moon, and Sun mean we see different sunlit portions of the Moon from Earth.
2. The synodic month, the time for a full lunar phase cycle as observed from Earth, is approximately 29.5 days.
3. We always see the same side of the Moon because its orbital revolution around Earth matches its rotational period on its axis, a state called tidal locking.
4. Rotation is spinning on an internal axis, while revolution is orbiting around another celestial body.

Answer:

1. THE MOON APPEARS IN DIFFERENT PHASES BECAUSE OF THE RELATIVE POSITIONS OF THE EARTH, MOON, AND SUN. THE SUN SHINES ON THE MOON AND WE SEE DIFFERENT PORTIONS OF THE MOON FROM EARTH.
2. IT TAKES ABOUT 29.5 DAYS FOR THE MOON TO GO THROUGH ONE FULL CYCLE OF PHASES.
3. FOR EVERY REVOLUTION THE MOON MAKES AROUND THE EARTH, IT COMPLETES ONE ROTATION ON ITS AXIS.
4. THE MOON ROTATES ON ITS AXIS (SPINNING MOTION) AND REVOLVES AROUND THE EARTH.
