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.

I think this question is totally wrong- W is Inner core,X is outer core,Y is mantle and Z Crust so how can they(SOF) is saying that 'B' is the correct option
Ans 14:
Class : Class 4

Ans 15:
Class : Class 4
Z IS THE CRUST AND Y IS THE MANTLE OS THE CORRECT ANSWER IS C AS CRUST TAKES MOST OF EARTHS SPACE
Ans 16:
Class : Class 5
The solution given is wrong. There is no explanation of why B is correct as Layer Y should actually be Mantle.
Ans 17:

Ans 18:

We have report SOF about this problem. I don't know why is it showing the wrong answer when ever I do this question. Who ever sees this question please report.I don't know why I cant report error. SOF is so bad.

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.
Ans 20:
Class : Class 5
the correct answer is bb b b b b b b b.
Ans 21:
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.

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.

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

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.

Dumb question
Ans 48:
Class : Class 4
Y is mantle, not crust and Z is the crust, so Z is also not ans.
Ans 49:

If you count from the centre or the layer after centre , the answer will be Mantle.

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!!!!!!
