Hi, @forumiasacademy 

SFG 2.0 Test 16, 3rd August

Please clarify following

Question 10

Statement 1. Sedimentary rocks are formed at earth's surface by the hydrological system.

The process should be weathering or erosion by agents ( which also include water) followed by deposition, settling and compaction.

Hydrologic system would include only one agent of weathering or erosion and not all. Also statement does not indicate settling and compaction which is necessary for sedimentation, and whole process is called lithification.

Hydrologic system is not mention in NCERT or wikipedia.


Question 29

Statement 1. Earth's interior underwent stratification which gave rise to a layered structure.

Word stratification is used for mainly sedimentary rocks. The layering of earth's exterior is specifically called "differentiation" due to density difference. 

Please clarify if we can use stratification


Question 32

Statement (a) Mass movements are aided by gravity.

There us difference between causative factor and aid factor. Gravity is one and only causative factor for mass movements. Aid would mean that mass movement can happen even without gravity, which is not true.

Similarly in question 9 

Which of the following can aid in physical weathering of a rock?

Word "aid" create confusion. Shouldn't it uses which of the following can cause physical weathering of a rock?


Thanks

q10:

Statement is correct. 

Sedimentary rocks are formed on the Earth’s surface by the hydrological system.

Formation involves: Weathering of preexisting rock, Transportation to a new site, Deposition of the eroded material, Lithification. Hydrological system includes all agents and their interrelated processes as well.

Q 29:

Stratification is arrangement into different groups or layers. The word stratification is correct here.

The stratification of Earth into its geologic layers was brought about by the formation of the Earth's iron core. The iron core was generated by a combination of radioactive decay and gravitation, which raised the temperature enough for molten iron to form. The migration of molten iron to the center of the Earth displaced the less dense materials toward the surface.

The statement is correct. Gravity is the main force responsible for mass movements. 

An advise: I think you are reading too much into words. UPSC will also use common words randomly. And if you read too munch into it, you may end up attempting very less questions.

I think you just have to read the whole unit in Laxmikanth that deals with the centre-state relations and all.

Is the power of a Governor to declare an area as a "disturbed area" under AFSPA a discretionary power or can he/she only make such a declaration on the advice of the state CoM?
787 views
@dragon_rider Generally, it is done with the aid and advice of the CoM. However, there can be cases where the CoM in a State does not want an area to be notified contrary to what the Central Government wants. In such cases, even if the Governor goes ahead and declares the area as disturbed contrary to the express advice of his council, his exercise of discretion cannot be challenged. This is because as per A. 162(2), if any question arises as to whether a matter is within the Governor's discretion or not, the Governor's decision on that point is final and binding. So, if the Governor makes such a call, it would be open for the State government to contest it on very limited grounds by way of judicial review. They would have to show that the Governor's decision was made with no application of mind, completely contrary to established principles of law, and the procedure in which the decision was taken was manifestly arbitrary. The court would not substitute its own views on the matter for those of the Governor's views. As long as the procedure adapted by the Governor is not vitiated by malice/ contrary to established principles, his decision cannot be assailed.

Consider the following statements regarding Basel III Norms:

1. Tier 1 and Tier 2 capital of a bank must be a minimum of 8% of its risk-weighted holdings

. 2. The Minimum Capital Adequacy Ratio including the Capital Conservation Buffer, is 10.5%.

DOubt :

Both statement will be correct only becoz it says BASEL 3 and not RBI's BASEL 3 norms for scb correct ???

Can someone explain the difference between the formation of geostrophic winds at tropopause and jet streams?

537 views

from what I have understood:

Convectional rise of air > high pressure at equatorial tropopause > Air descends at poles and creates low pressure at polar tropopause > pressure gradient + high speed + Coriolis force  = high-speed winds parallel to the pressure gradient.

Now, what are these winds called? Geostrophic or Jetstreams? If any one, how is the other one formed?

And if the jet stream is a subset of geostrophic, what other geostrophic winds are there?

@panbhi26967 Thanks for the Political Parties doubt --> Just found out that there are no provisions in RPA for EC to regulate internal democratic matters of a Party. It can only call for the Memorandum and Rules of the Party and an Undertaking that the party will stand by constitution etc etc.

Could someone explain the line on Deputy Chairman? Does this mean that once the member is elected as the Dy. Chairman is elected, he/she is immune to ADL?

@tanvi_vats If he "voluntarily leaves" - that is gives up the membership of the party from which he is elected. He cannot join any other political party. He cannot be expelled by his political party. If a normal MP voluntarily leaves - will be disqualified.

@vikhcu2073 But according to ADL, in case an MP/MLA "voluntarily leaves" they might be disqualified; in this case the Dy Speaker is an exception then, is that what you are trying to say?
