Question

Choose the correct option. Statement 1: The shape of the moon changes every day and the various shapes seen during a month are called phases of the moon. Statement 2: Moon has no light of its own. We see only that part of the moon, which reflects the light of the sun to us. The position of the moon changes due to its revolution around earth and hence the portion of the moon reflecting the light of the sun to us.

Answer 1

Hint : In this question we will come to know all the facts about the moon, its shape, light, positions of the moon, whether the moon changes due to its revolution around earth. And some facts and information about the moon.

Complete Step By Step Answer:
Statement 1 explanation:
Changing shape of the moon, also called phases of the moon, is caused by changes in the part of the moon illuminated by the sun facing the moon.
We see the moon because of the sunlight reflected towards the earth. At any time, the sun can illuminate only half part of the moon. The other half of the moon does not receive any sunlight because of its spherical shape. Depending on the relative positions of the sun, moon, and the earth, different proportions of the semi-sphere-shaped illuminated half of the moon faces the earth, causing the shape of the moon visible from the earth to change.
On a full moon day, when the moon appears as a complete circle, the earth is positioned directly between the moon and the sun. Because of this the illuminated surface of the moon fully faces the earth, making the moon appear round. At the other the earth is positioned away from the direct connecting sun and moon. Further the earth from this line, smaller is the illuminated part of the moon directed towards, and visible from earth. On a new moon day, the earth is positioned farthest from this line joining the sun and moon. AS a result, the moon is seen as a thin crescent only.

Statement 2 explanation:
Unlike a lamp or our sun, the moon does not produce its own light. Moonlight is actually sunlight that shines on the moon and bounces off. The light reflects off old volcanoes, craters, and lava flows on the moon’s surface.
The perceived brightness of the moon from Earth depends on where the moon is in its orbit around the planet. The moon travels once around Earth every 29.5 days, and during its journey, it is lit from varying angles by the sun.
The moon is at its brightest when it is 180 degrees away from the sun from our perspective (picture the sun, Earth, and moon in a straight line). At this time, the full half of the moon's surface facing the sun is illuminated and is visible from Earth. This is what is known as a full moon.
Here, both the Statements are correct.

Note :
One good fact about this question is you do not have to remember the complete theory, just you have to go through both the explanations, and you will come to know all about both the statements. And just remember that the phases of the moon occur because it revolves around the Earth and the light from the Sun continuously changes due to the presence of Earth between the Moon and the Sun.
