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.

Shivesh Senthilkumar from vels vidyashram, chennai

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.

Ans 28:

Sunishka Khatri from Global Indian International School, Pune
Class : Class 6
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.

Diya Jasmina from Samsidh MLZS, Bengaluru
Class : Class 4
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 34:

Shailaja Divakar from Chennai public school global school, London

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.

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.

Ans 4:

Saarth Agrawal from Podar International School , Mumbai
Class : Class 6
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 5:

Advait Avadhoot Joshi from Arya Gurukul Nandivli, Kalyan
Class : Class 5
It should be mentioned NEW MOON AND FULL MOON or either Waning or waxing

Ans 6:

Lakshana from SBOA School and Junior College, Chennai

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
