"First Quarter" and "Third Quarter"
(Moon half-illuminated.)
The moon's phases can be seen from the earth, but not by an observer on the moon. Similarly, the earth's phases can be seen from the moon, but not by an observer on the earth.
The different shapes of the moon seen from Earth are called lunar phases. These phases include new moon, first quarter, full moon, and last quarter, which result from the changing positions of the moon, Earth, and the sun.
That is sometimes what the Moon is called. Seen from Venus the Earth and Moon would be seen as a pair of bright planets up to 0.5 degrees apart at opposition, which is the diameter of the Moon as seen from Earth.
The changing views of the moon as seen from Earth are called moon phases. These phases result from the relative positions of the sun, Earth, and moon, causing different portions of the moon to be illuminated.

The changing views of the moon as seen from Earth are due to its phases, which are a result of the changing positions of the moon, Earth, and sun. The moon goes through a cycle of phases, including new moon, crescent, first quarter, gibbous, full moon, gibbous, last quarter, and crescent, as it orbits Earth. These phases are the result of the varying amounts of sunlight that illuminate different parts of the moon's surface as seen from Earth.
The changing shapes of the moon are called lunar phases. These phases are caused by the relative positions of the sun, Earth, and moon, resulting in different portions of the moon being illuminated as seen from Earth.
