I think the answer key of these three questions are given wrong.
Q1) How does the karst topography and erosion by ground water be explained by Sun. so it should be d) Neither 1 or 2.
Q2) Ploughing and cultivating soils by human beings – Anthropogenic process. so answer should be c) 1 and 3 only.
Q3) In relatively large amounts, the soil supplies nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur; these are often called the macronutrients.
In relatively small amounts, the soil supplies iron, manganese, boron,
molybdenum, copper, zinc, chlorine, and cobalt, the so-called micronutrients.
Source-
Plant nutrition – Wikipedia
so answer a) 1 and 4 only. -
Its really strange, Carbon is probably the Macroest of all macro elements
-
4/5 but why is Carbon not a macro nutrient, i mean its THE most macro of all macros in all biological matter 😛

Bhai kon si class ki NCERT ka konsa chaper hai.

Hi di, how’s your preparation ?
Coming to question, weathering means ”wear away or change the appearance or texture of (something) by long exposure to the atmosphere.”
Weathering is normally associated with rocks, but soil too is derived from rock and is considered earth matter, part of earth’s crust. Hence, by ploughing soil, humans enable new interactions of soil particles with atmosphere, helping chemical reactions and physical changes to take place affecting texture of soil.
I hope you got it. -
Yeah I have the same doubt.

Iron is not a macro plant nutrient but it’s micro… -
Sir, Please explain 5th question. I have confusion with the options.
-
Thanks..
-
Does ploughing help in weathering actually?..It disturbs the composition of soil..yes ..but weathering is breakdown of rock particles no?..
-
weathering is on rocks no?..rocks turn soil by weathering..so ploughing is right?..Not sure

NCERT Class 11th Physical Geography Chapter 6 Geomorphic process.
Biological weathering Pg.51
“Human beings by disturbing vegetation,
ploughing and cultivating soils, also help in
mixing and creating new contacts between air,
water and minerals in the earth materials.” -
It is Class 11 Biology. Chapter 12.

Q.5 I think iron is not a macro nutrient. -
great, thanks – can I ask which NCERT ?

NCERT on macro and micro nutrients https://uploads.disquscdn.com/images/16604f46e25438556acb365b78753abe657da665aa3dcb3ba25583909c9d55f0.jpg

Iron is definitely a micro nutrient bro, the answer here is wrong. Whether, carbon is a macro nutrient or not is however debatable, according to NCERT the macro nutrients are N, P, K, Ca, S and Mg. However, in a few sources on the internet, Carbon , Hydrogen and Oxygen are also mentioned as macro nutrients derived from the air, now only god knows what upsc expects.

A natural harbor is a landform where a part of a body of water is protected and deep enough to furnish anchorage.
Based on this definition, it is obvious that natural harbors are slightly inland, therefore, it does not have access to the ocean easily and there can be hurdles while connecting to the ocean (therefore ‘1’ is wrong). And also, since it is protected by storms (‘2’ is also wrong). Hence answer will be 3 only nodi ji. -
NCERT says so and Humans are after all biological organisms. 🙂

by Ploughing and cultivating soils by human beings,,,,,soil gets exposed to atmosphere and chemical attack..hence weathering,,,
ploughing is not mentioned directly in link,,,but logically we can come to conclusion,,, -
A natural harbor is a landform where a part of a body of water is protected and deep enough to furnish anchorage. so it is not directly conected. Having a protected harbor reduces or eliminates the need for breakwaters as it will result in calmer waves inside the harbor.
-
If humans have died and then their spoiling body weathered some rock. it would have been biological but this is simply anthropogenic.

Can you enlighten about option 1 and 2 of question 4

Q5
Few Facts about some port:- Among major ports, Mumbai is the biggest. Kandla is a tidal port. Marmugao enjoys the second position by value of the tonnage of the bulk of which is export of Iron core. Vishakhapatnam is the deepest land-locked and protected port. Chennai has an artificial harbour, Kolkata is a riverine port, Haldia has a fully equipped containerised berth. -

Doubts in Q2. Option B, please enlighten.
-
Carbon , O2 and H2 are Macro-nutrients …..derived from air and water
Pls check :
https://en.wikipedia.org/wiki/…Yes VSKP is the Largest Natural harbour of India.
Can you enlighten about option 1 and 2 of question 4

Bhai 1st question ka 1st option pata nahi tha. Issliye skip kiya tha. But tumhara logic sahi hai. But I would say 2nd option generally sahi ho jayega. I mean due to intense cold river Indus ek time peih freeze ho jayegi. That is what I think.
-
3/5 time -00:01:51
-
Bhai kahi peih ‘macro’ likha hai kahi peih ‘essential’ category meih dala hai. H,C and O koh
-
same here.
i think biological weathering > caused by living organisms > hence human s too included?
also doubtful abt 2nd questn exogenic -
No.
-
River flow is not always the result of Sun’s heat. For example — There are perennial rivers like Indus which will keep flowing even in the winters though with less intensity and continue to erode. This was my logic while marking. I may not be right here.
Rest we are on same page. 🙂
-
hahahaha
-
😀
-
Q-1,Sun heat causes all forces like mechanical weathering, rain, river flow, wind
Q.4- Visakhapatnam is natural but not the deepest harbour of India, so I have doubt,
Q5-same doubt here. -

#5. I have doubt about this question. How Carbon is excluded from macro nutrients and iron is included in this.
You can see the wikki for reference where iron is mentined as micro and carbon as macro nutrients.
https://en.wikipedia.org/wiki/Plant_nutrition -
2/5..Aaj toh hava nikal gyi..
-
Apparently carbon, hydrogen and oxygen are also macronutrients according to many sources on the interweb. Was always under the impression that the macro nutrients were only N, P, K, Ca, S and Mg (thanks to our outdated NCERTs). Anyhow, learned something new today, thanks forumias!

1st question ka second option. Any insight why it is not wrong?
-
I too had a similar doubt Murinder, I don’t think second option comes under Biological activity.
The option is not correct in my considered opinion. 🙂
-
2 of 5
-
the macronutrients: nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), sulfur (S), magnesium (Mg) ( https://www.google.co.in/?gfe_rd=cr&ei=PSufWN_HHPPs8Aer6LjYBA#q=macro+plant+nutrients )
These are Macro Nutrients. The answer for Question no. 5 should have been only 1 and 4. and not 1,3 and 4.

Thanks forumias,I will

Bhai its Proime Ministor. Aur aaj forumias neih quiz 20:02 peih upload kiya . Lol
-
Prime Minister ke naam ka post mortem kar diye tum? 😛
-
Lol ,yeih hindi to english wala transition sahi hai. Thanks for telling – Carbon,Oxygen and Hydrogen are essential component of plant’s life cycle. I was not able to recollect. Now I will remember it.
-
Carbon,actually, doesn’t come under any of these categories. Carbon,Oxygen and Hydrogen are essential component of plant’s life cycle.
Plant can survive in absence of some macro or micronutrients. But without C,H,O, a plant can’t survive.
So yes, option a ही होना चाहिये.

Yes boss I also think so.
In relatively large amounts, the soil supplies nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur; these are often called the macronutrients. In relatively small amounts, the soil supplies iron, manganese, boron, molybdenum, copper, zinc, chlorine, and cobalt, the so-called micronutrients. -
Bhai toh carbon bhi toh nahi hai. Option should change na.
-
2nd question ka second option. Anyone?
-
5th answer option should be (a), Carbon is not a macro nutrient, calcium is.

Good.

It is not.
Macro: Nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), sulfur (S), magnesium (Mg) the micronutrients (or trace minerals): boron (B), chlorine (Cl), manganese (Mn), iron (Fe), zinc (Zn), copper (Cu), molybdenum (Mo), nickel (Ni). and cobalt (Co)
