Z is the crust as it is at the first. The solution has been written wrong because it is from planets question.

Ans 7:

Class : Class 4
Solution (living and non-living beings) is wrong as it is not related to the questions (Earth's various layer). SOF trainer kindly look into this. thanks

Ans 8:

Class : Class 4
They have given the solution of another topic in the topic of Earth and Universe.

Ans 9:

Class : Class 6
The solution is mistaken in the end but the answer is b because surface means top and top of y which is mantle is crust and crust makes most of the Earth as it ids the largest portion.

The correct answer is C. I am disappointed with the SOF Olympiad. I recommend to not enroll the students for any of the Olympiad, as the material is not adequate and there are too many errors which will confuse children to make their concepts. We are pressurizing our children to take this exam and perform. But actually it will confuse our children instead of making their concept strong.

Ans 32:

Class : Class 3
ok, why is the answer to almost all questions in these chapters are wrong. They tried to copy the book but they (mistakenly) wrote the wrong answer. The correct answer should be E (made it myself cuz the answer is not there) Surface of Z is the crust. Man, these SOF people need to first read what they have written then upload it so we can study for our test. Even the Admin (Who has the master answer) has no words to say!!!!!!

Ans 33:

Class : Class 4
the question should be incorrect and the solution is wrong

All of you're worrying. The answer is B as per the MTG olympiad book. there the options were:W and X are liquid layersLayer above Y is crustLayer Z makes most of the earth's volumeall of theseTHE OPTION B LAYER ABOVE Y IS CALLED CRUST is correct in the book.As that is the ground and above the ground is the sky and atmosphere which is called crust and here its written SURFACE ABOVE Y IS CRUST because Y is land and above land is crust. All of you were thinking they told Y as crust and that's wrong but they said Surface above Y which is Z . They're correct.

Ans 38:

correct answer is 'c' as the middle 2 part are the cores of the earth

!Read This! You need to read this answer before writing your answer. Everyone is right It should be updated but do not write the wrong answer correct and the correct answer wrong and the wrong answer correct! They are bigger than us and they know more than us. So, the conclusion is that the B option is correct and the else options are wrong.

Ans 40:

Class : Class 4
Y is mantle, not crust and Z is the crust, so Z is also not ans.

Ans 41:

Class : Class 7
The solution of this answer is wrong. Don’t follow the solution.

Ans 42:

Class : Class 9
The answer is B because they are saying the SURFACE of Y is called Crust .Right , because Crust is called the surface of Mantle .

Answer is A as :W inner coreX outer core Y mantleZ crustThey have not specified alsoAnd crust does not make up most of the Earth's volumeIt is a logical type of questionIf W is core then also C is wrong as W is making up most of the Earth'svolume so answer is A only

Ans 61:

Class : Class 6
The answer is C and not B because they told to select the correct option. Y is mantle and the option B they told crust. As Z is crust and covers most of the earth surface, it should be C.

Ans 62:

Class : Class 5
guys, calm down. we do not stand on the crust, we stand on the earth. so z is the earth, y is the crust, x is the outer core and w is the inner core.If you go and see the information of the exam, the have not mentioned mantle, so what ever information is given, you have to follow it to get the answer. So the answer is B.

Ans 63:

Class : Class 10
The solution is related to the chapter of plants.

Ans 64:

Class : Class 6
crust is the topmost layer

Ans 65:

Class : Class 6
Z is the crust. So answer should be C. Please update the solution as the solution also seems to be wrong. Diagram shows four layers and outer layer will be crust.

It should be written as New moon and Full moon as anyone could be confused that the dark side is the moon. I also put gibbous with the same thought. If it would have been marked then it would have been easier to say that the answer is the crescent moon.

Ans 2:

Class : Class 9
@Lakshana, @Saarth Agrawal and @Prath exactly

Ans 3:

Class : Class 5
It should be mentioned NEW MOON AND FULL MOON or either Waning or waxing

Ans 4:

Class : Class 6
I got confused and wrote gibbous thinking that the dark side of the moon is visible. You should name the other moon phases with waning and waxing or name the full moon or the new moon
