I think that c is correct as the moon is behind the earth , so there will be no light reaching the moon . Thus, it will be new moon .

Ans 7:

Class : Class 5
moon does not have its own light it reflects of sun and as it is completely blocked by earth the suns light does not reflect and we do not see any phase of the moon .hence ans is c

THE MOON IS NOT STRAIGHT TO THE EARTH. MOON HAS SLIGHT SLANTING REVOLUTION. THAT IS WHY WE HAVE DIFFERENT PHASES OF THE MOON. IF THE MOON IS AT THE POSITION OF..... SUN---EARTH---MOON.......SO THAT WILL BE FULL MOON. FULL MOON IS GIVENN AT OPTION B. SO MOST OF US LIKE ME DID B BUT IT IS SHOWING C AS THE CORRECT ANSWER. BUT AS I THINK THAT EVERYTHING HAS A REASON.1. THE SOLUTION IS THE MEANINGFUL WAY IT IS GOOD. BUT IF YOU OPPOSE THIS, SO 2. THAT THE CHART IS SHOWING THAT....... SUN-----EARTH-----MOON. SO ACCORDING TO THE CHART, IT IS A LUNAR ECLIPSE IN WHICH THE MOON IS COMPLETLY BLACK. SO OPTION C HAS A REASON. SHARE YOUR IDEAS ALSO.

IT SHOULD NOT BE C! B IS THE RIGHT ANSWER. IF SUN EARTH MOON= FULL MOON. IF SUN MOON EARTH = NEW MOON. .

Ans 21:

Ans 24:

Class : Class 5
Full moon occurs when light is spread all over the surface of the moon...but in the picture the moon is blocked by earth and the moon will remain dark.Hence,the answer is (c) new moon

Ans 25:

Class : Class 9
How come it is C ? This is insane!!!

Ans 26:

Class : Class 5
It is a full moon and I had enough of your mistakes SOF now, I am going to beat you people.

Ans 27:

Class : Class 5
This is absolutely incorrect. SOF should verify such answers. The question is about the phase of the moon. Even if it is a lunar eclipse it falls on a full moon day. The answer is B

Ans 28:

Class : Class 6
how is this possible

Ans 29:

Class : Class 5

Ans 30:

Class : Class 5
According to any phases of the moon diagram, a full moon will be behind the Earth. Even lunar eclipse will be on a full moon day . New moons position will be the opposite of a full moon,i.e. between the earth and sun

The three dots are not at the same depth. P and Q are at the same depth, but R is slightly above both of them.

Ans 6:

Class : Class 8
r is slightly above them so it has less pressure and there is a block above p so the answer is (C)
