RRB Junior Engineer / DMS / CMA 2019 · Question 3437 of 3719
The correct answer isWaxing phase of the moon. Important Points The revolution of the Moon around the Earth makes the Moon appear as if it is changing shape in the sky. The "phases" of the Moon are caused by the different angles from which we see the bright part of the Moon's surface. There are four major shapes. New Moon: The lighted side of the Moon faces away from the Earth. This means that the Sun, Earth, and Moon are almost in a straight line, with the Moon in between the Sun and the Earth . The Moon that we see looks very dark. First Quarter: The right half of the Moon appears lighted and the left side of the Moon appears dark. During the time between the New Moon and the First Quarter Moon, the part of the Moon that appears lighted gets larger and larger every day, and will continue to grow until the Full Moon. Full Moon: The lighted side of the Moon faces the Earth. This means that the Earth, Sun, and Moon are nearly in a straight line, with the Earth in the middle. The Moon that we see is very bright from the sunlight reflecting off it. Last Quarter: Sometimes called Third Quarter. The left half of the Moon appears lighted, and the right side of the Moon appears dark. During the time between the Full Moon and the Last Quarter Moon, the part of the Moon that appears lighted gets smaller and smaller every day. It will continue to shrink until the New Moon, when the cycle starts all over again. When the shadow is shrinking and progressing towards a full moon, the moon phase is waxing. When the shadow is progressing towards a new moon, the moon phase is waning.
