Ans 1:

Ans 3:

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 4:

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 5:

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 6:

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

Ans 7:

Class : Class 5
solution given is wrong

Ans 8:

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

Ans 9:

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 10:

Class : Class 4
crust is the topmost layer

THe solution is fully wrong, somebody report it direct to SOF founder.

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!

The diagram is also not labelled correctly

Ans 15:

Class : Class 7
The Toppest layer is the crust not the mantle. Y shows below Z ,and Zealand means mantlemail which is below the crust

Ans 16:

Class : Class 6
Z is crust and Y is mantle

Ans 17:

Class : Class 5
This is wrong

Ans 18:

Class : Class 5
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 19:

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

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

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.

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.
