Question

explain the phases of moon for class 8th

Answer 1

The 8 phases (in order) are:

(1)New moon

(2)Waxing Crescent

(3)First Quarter

(4)Waxing Gibbous

(5)Full moon

(6)Waning Gibbous

(7)Third Quarter

(8)Waning Crescent

1. New Moon

This is the beginning portion of the moon’s phases. A new moon happens when the moon is located between the sun and the Earth. We typically cannot see a new moon since the dark side of the moon is facing the Earth.

2. Waxing Crescent

During the Waxing Crescent phase, the moon travels east in the sky. The waxing crescent phase of the moon begins once we can see a tiny sliver of the moon after a new moon. There are times when you might be able to see the rest of the moon as well, even if it is dark because of a phenomenon called “earthshine” in which the Earth reflects sunlight to the moon.

3. First Quarter

The next phase of the lunar cycle is the first quarter. During this phase happens when you can see half of the moon that is illuminated. The name “first quarter” comes from the fact that at this stage the lunar cycle is 1/4 of the way completed. Not everyone will see the same halves of the moon lit up during this phase, primarily because it depends on your location.

4. Waxing Gibbous Moon

This phase essentially covers the time between the first quarter phase and the full moon phase. the words waxing gibbous describe what the phase is pretty well. Waxing means growing larger, and the word gibbous refers to the shape, so waxing gibbous essentially means “growing shape”. The moon will get more and more illuminated until the moon is fully illuminated, which starts the next phase.

5. Full Moon

As you probably already know, a full moon is when the entire moon face is completely illuminated by the sun. Full moons occur when the sun and moon are on opposite sides of Earth. Technically the moon is only 100% illuminated by the sun for a few moments, but this phase also covers when the moon looks full but isn’t.

When the moon is at its closest point to the Earth in its orbit it is called a supermoon, and at its farthest point, it is called a micro-moon. Another cool thing that occasionally happens during a full moon is when the moon passes through our Earth’s shadow, called a lunar eclipse. During a lunar eclipse, the moon will be a reddish color, like the picture above shows.

6. Waning Gibbous Moon

Like we covered above, waxing means increasing and waning means decreasing. So, in this case, the waning gibbous moon means that the shape is decreasing. The waning gibbous phase lasts until the moon is half illuminated.

7. Third Quarter Moon

This phase is basically the exact opposite of the first quarter moon. This is when the moon is half lit up in the sky, and it also signals when the lunar phase is 3/4 of the way completed.

8. Waning Crescent Moon

This is the final stage of the lunar cycle. This phase starts when the sun illuminates less than half of the moon and continues on until the New Moon phase. During this phase, we can also see the effect of “Earthshine”, just like we can during the new moon phase

Answer 2

Answer:

The phrases of moon are as below:

• New Moon
• Waxing Crescent
• First Quarter
• Waxing Gibbous Moon
• Full Moon
• Waning Gibbous Moon
• Third Quarter Moon
• Waning Crescent Moon

Explanation:

The side of the moon that faces the sun will be illuminated as it circles around the planet Earth. Because of the sun's brightness, the moon will be illuminated. The moon phases are the various shapes of the lighted part of the moon that can be seen from our planet, Earth.

• New Moon: This is the initial part of the phases of the Moon. The new moon occurs when the Moon is situated between the Sun and the Earth. We usually cannot see the new moon because the dark side of the Moon is towards the Earth.
• Waxing Crescent: During the Waxing Crescent phase, the Moon travels east across the sky. The waxing crescent phase of the Moon begins when we can only see a small portion of the Moon after the new moon.
• First Quarter: The next phase of the lunar cycle is the first quarter. It is during this phase when you can see the half moon that is illuminated. The name "first quarter" comes from the fact that this stage accounts for 1/4 of the completion of the lunar cycle.
• Waxing Gibbous Moon: This phase essentially covers the time between the first quarter phase and the full moon phase. The words waxing gibbous describe what the stage is very well. Waxing means to grow up, and the word gibbous refers to size, so waxing gibbous essentially means "increasing size".
• The full moon: A full moon occurs when the entire Moon face is completely illuminated by the Sun. When the Moon is at its closest point to Earth in its orbit it is called a supermoon, and at its farthest point it is called a micromoon.
• Waning Gibbous Moon: As we mentioned above, waxing means increasing and waning means decreasing. So, in this case, a decreasing gibbous moon means that the size is decreasing. The diminishing gibbous state lasts until the moon is half illuminated.
• Third Quarter Moon: This phase is basically the exact opposite of the first quarter moon. It occurs when the moon is half illuminated in the sky, and also indicates that the lunar phase is about 3/4th of its completion.
• Waning Crescent Moon: This is the last phase of the lunar cycle. This phase begins when the Sun illuminates less than half of the Moon and continues till the new moon phase.
