Z is crust and Y is mantle

Ans 5:

Class : Class 4
Z is the crust as it is at the first. The solution has been written wrong because it is from planets question.

Ans 6:

Class : Class 4
If you count from the centre or the layer after centre , the answer will be Mantle.

Ans 7:

Class : Class 5
the correct answer is bb b b b b b b b.

Ans 8:

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

Ans 9:

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 10:

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 11:

Class : Class 3
Y is mantle.

Ans 12:

Class : Class 4
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 13:

Class : Class 4
The options are wrong.The solution given by sof is wrong.

Ans 14:

Class : Class 5
Options for this question are wrong. Need to update the question.

Ans 15:

Class : Class 5

Ans 16:

Class : Class 5
The Toppest layer is the crust not the mantle. Y shows below Z ,and Zealand means mantlemail which is below the crust

Ans 17:

Class : Class 5
Answer is b

Ans 18:

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 19:

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 20:

Class : Class 6
Y is mandle

Ans 21:

Class : Class 5

Ans 22:

Class : Class 4
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 23:

Class : Class 4
they have given an incorrect solution,dog,elephant and wood are not related to this question.

Ans 24:

Class : Class 5
