P is made up of iron so a is wrong

Ans 11:

Class : Class 4
P is the molten part made up of nickel and iron(p is not molten). R is the hottest part of Earth which is solid( P is the hottest part of Earth which is solid).Q is connected to surface with the help of volcanoes( R actually has magma in it ). Minerals and oil deposits are found in the part S. and option D is only corect

ans is d

Ans 14:

Subject :NSO    Class : Class 5

Ans 1:

Class : Class 8
a is correct because there willbe soil erosion without trees

Ans 2:

Class : Class 7
B is the answer!

Ans 3:

Class : Class 9
B is the correct answer

Ans 4:

Class : Class 6
I think the answer should be b as after a forest gets destroyed by a forest fire ,new trees will grow as the remain of the trees will decompose and make the sol fertile.

Ans 5:

Class : Class 7
i think the answer should be B because the statement 'New trees will grow quickly to replace the burnt ones as the ash of the burnt trees will make the soil more fertile' is also true

Ans 6:

Class : Class 7
BBBB IS THE ANSWER

Ans 7:

Class : Class 2
ddddddd

Ans 8:

Class : Class 7
the answer is B.

Ans 9:

Class : Class 7
I agree with Ishan as trees cannot grow very quickly...But I did B at my first attempt

Ans 10:

Class : Class 9
I think the answer is B

Ans 11:

Class : Class 9
Actually, forest fires lower the level of nitrogen in the soil. Since nitrogen quantities in the soil is extremely important for plant growth, lowered level of nitrogen is a big barrier in plant growth

Ans 12:

Class : Class 5

Ans 13:

Class : Class 5
The question and choices given are a bit tricky. The correct answer is A because the language of (iv) is deceptive and says "new trees will grow quickly to replace the burnt ones". You have to understand that "new trees" won't grow quickly, you can only sow small plants not trees.

Ans 14:

Class : Class 9
I think B is correct option as ash acts as a fertilizer for plants (even if in small quantities). Master Answer (Admin, Revisewise) EXPLAIN the answer to all of us.

Ans 15:

Class : Class 4
I think B is the correct answer

Ans 16:

Class : Class 8
WHAT! B is correct, not A. The answer is B, NOT A!

Ans 17:

Class : Class 9

Ans 18:

Class : Class 6
Come on Snigdha! The CORRECT ANSWER IS (B)! Ash makes soil fertile 'cause it's organic , dude! How will trees not grow?(P.S.- please don't think about Ash in Pokemon. Please, don't)🤦‍♂️🤦‍♂️

Ans 21:

Class : Class 6

Ans 22:

Class : Class 8

Ans 23:

Class : Class 5

B B B B B B . B B B B B B BB BB B B B B B . IS THE ANSWER

Ans 27:

Class : Class 5

Ans 28:

Class : Class 5
How ??? It should be b.As ash is an organic matter. the process of nitrogen fixation will make the soil fertile . Please tell .Why????

Ans 29:

Class : Class 9
Ash is an organic matter so the answer should be B

Ans 30:

Class : Class 7
THe AntwerpThe answer is (A) because if forest fire occurs there will not be any trees and soil erosion can happen and All the ashes including soil may erode and then how can it make the soil fertile

Ans 31:

Class : Class 5
It is certainly B as ashes of any organic matter makes soil fertile.

Ans 32:

Class : Class 6
B should be the correct answer

Ans 33:

Class : Class 9
Answer is B as ash is an organic

Ans 34:

Class : Class 7

Ans 35:

Class : Class 7
The answer should be B.

Ans 36:

Class : Class 8
B IS THE CORRECT ANSWER AS BURNING OF WASTE CROPS AFTER HARVESTING OF GRAINS IS STANDARD METHOD OF INCREASING SOIL FERTILITY

Ans 37:

Class : Class 5
yes B is the answer as the ash contains minerals from the other trees.. i agree that the process of nitrogen fixation will make the soil fertile.........

I DONT UNDERSTAND WHY IS IT D

Ans 9:

Class : Class 9
The correct answer is D

Ans 10:

Class : Class 2
It is D. Imagine it this way. There is a heavy rock on the seesaw and we sit closer to the middle. It will be hard for us to go down and rock up. But if we sit at the edge of the seesaw, we will go down and the seesaw will go up.

Why C is incorrect answer? During Summer month at noon there will be shadow exactly under feet.

Ans 2:

Class : Class 7

Ans 3:

Class : Class 9
yes c is correct kindly rectify

Ans 4:

Class : Class 6
The answer should be C.

Ans 5:

Class : Class 6
I think it's option B, as at noon we do have a shadow although it's very small, it's not like there's no shadow at all. If my answer is wrong, kindly rectify

Ans 6:

Class : Class 8
I suppose that option'B' is the correct answer. If my thinkings are wrong, then please kindly make me understand with a reason i understand in simple words. If my answer is correct then please, please, please comment on it. My goal here is not to give long lectures, but to find the correct answer to this question.

Ans 7:

Class : Class 9
It should be (b) because (c) shows that there is no shadow at noon, however even in summer, there is a small shadow at noon. Therefore the answer should be (b).
