!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.

The Toppest layer is the crust not the mantle. Y shows below Z ,and Zealand means mantlemail which is below the crust

they have given an incorrect solution,dog,elephant and wood are not related to this question.

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.

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.

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

the correct answer is bb b b b b b b b.

## Ans 29:

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

## Ans 30:

Class : Class 8
The diagram is also not labelled correctly

## Ans 31:

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.

## Ans 32:

Class : Class 4
correct answer is 'c' as the middle 2 part are the cores of the earth

## Ans 33:

Class : Class 6
crust is the topmost layer

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.

Class : Class 8
Dumb question

## Ans 36:

Class : Class 7
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 37:

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.

Class : Class 4

## Ans 39:

Class : Class 6
Z is the crust as it is at the first. The solution has been written wrong because it is from planets question.

## Ans 40:

Class : Class 8
The answer is B because they are saying the SURFACE of Y is called Crust .Right , because Crust is called the surface of Mantle .

The solution is completely wrong!Does anyone know the email ID,mobile no. or address of anyone working with SOF? We could inform them and then if that person can do it well and good or that person could tell the correct person.We need the solution to be correct.

Class : Class 5

## Ans 46:

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.

Class : Class 7

## Ans 48:

Class : Class 6
Z is crust and Y is mantle

## Ans 49:

Class : Class 8
Solution is wrong

## Ans 50:

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 51:

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

## Ans 52:

Class : Class 6
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 53:

Class : Class 7
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 54:

Class : Class 5
They have given the explanation of some other question in the solution though, B is the correct answer.

Class : Class 1

Class : Class 3
Y is mantle.

What a silly answer! Are dogs, trees and pumpkins growing inside the layers of the earth that they have given such a silly solution? What cheek!

## Ans 62:

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
