Question

describe all phases of moon with definition

Answer 1

New moon: it is when we cannot see the moon because we are looking at the unlit half of the moon. It occurs when the moon is directly between sun and the earth.
Waxing Crescent: it is when we see the moon in Crescent shape and it increases in size from one day to next. It is usually seen by the people living in West
The first quarter moon (or a half moon):is when half of the lit portion of the Moon is visible after the waxing crescent phase . It comes a week after new moon.
A waxing gibbous moon:occurs when more than half of the lit portion of the Moon can be seen and the shape increases ("waxes") in size from one day to the next. The waxing gibbous:phase occurs between the first quarter and full moon phases.
A full moon:is when we can see the entire lit portion of the Moon. The full moon phase: occurs when the Moon is on the opposite side of the Earth from the Sun, called opposition.A lunar eclipse can only happen at full moon.
A waning gibbous: moon occurs when more than half of the lit portion of the Moon can be seen and the shape decreases ("wanes") in size from one day to the next. The waning gibbous phase occurs between the full moon and third quarter phases.
The last quarter moon (or a half moon) :is when half of the lit portion of the Moon is visible after the waning gibbous phase.
A waning crescent moon:is when the Moon looks like the crescent and the crescent decreases ("wanes") in size from one day to the next.
An old moon: is a moon with only a tiny bit of the moon seen in the corner, about to turn into a new moon.

Answer 2

new moon- when the side of the moon facing us gets no sunlight at all, we cannot see the moon . This phase is called New moon.(day1)

Crescent moon- As the moon moves along its orbit,a small portion of the side facing us gets sunlight. This phase is called crescent moon. (day2)

Half moon- In a week we can see the half of the moon.(day7)

Gibbous moon-After three more days,we see three quarters of the moon. This is called gibbous moon.(day10)

Full moon- In two weeks, the entire side facing us gets sunlight. We can then see the full moon. (day14)

After this the phases reverse
