10000 Questions for Prelims 2020 | Prelims 2020 Marathon
Dear Friends,
Let is share and post / paste here questions of various test series . If we crowd source enough, we know that questions will come from here. There was a thread of crowd sourced questions in the past, where @wunwun @burger @pizza and all had contributed and that year we had many questions come from there.
Let us start this initiative. Also please follow the convention followed last year by @neyawn Sir, let us number the questions in a serial number.
Here I am starting

Select correct
a) 1 and 2 only
b) 2 and 3 only
c) 2 and 4 only
d) None of t
With reference to the ‘LADIS’ – Least Available Depth Information System, consider the following statements
1. LADIS will ensure that real-time data on least available depths is disseminated for ship/barge and cargo owners so that they can undertake transportation on National Waterways.
2. It is designed by the Inland Waterways Authority of India (IWAI) to facilitate the day-to-day operations of inland vessels.

B is correct.
Divisions of the Ocean Floors
The ocean floors can be divided into four major divisions: (i) the Continental Shelf; (ii) the Continental Slope; (iii) the Deep Sea Plain; (iv) the Oceanic Deeps.
Besides, these divisions there are also major and minor relief features in the ocean floors like ridges, hills, sea mounts, guyots, trenches, canyons, etc.
Continental Shelf
The continental shelf is the extended margin of each continent occupied by relatively shallow seas and gulfs. It is the shallowest part of the ocean showing an average gradient of 1° or even less. The shelf typically ends at a very steep slope, called the shelf break. The width of the continental shelves varies from one ocean to another. The average width of continental shelves is about 80 km.
The shelves are almost absent or very narrow along some of the margins like the coasts of Chile, the west coast of Sumatra, etc.
Continental Slope
The continental slope connects the continental shelf and the ocean basins. It begins where the bottom of the continental shelf sharply drops off into a steepslope. The gradient of the slope region varies between 2-5°. The depth of the slope region varies between 200 and 3,000 m. The slope boundary indicates the end of the continents. Canyons and trenches are observed in this region.
Continental rise
The continental rise is an underwater feature found between the continental slope and the abyssal plain. This feature can be found all around the world, and it represents the final stage in the boundary between continents and the deepest part of the ocean. The environment in the continental rise is quite unique, and many oceanographers study it extensively in the hopes of learning more about the ocean and geologic history.
Abyssal plain
An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 metres (9,800 ft) and 6,000 metres (20,000 ft). Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth’s surface. They are among the flattest, smoothest, and least explored regions on Earth. Abyssal plains are key geologic elements of oceanic basins (the other elements being an elevated mid-ocean ridge and flanking abyssal hills).

With reference to Biofertilisers, consider thefollowing statements:1. These are biologically active substances thatare applied in soil to enrich the soil with nitrogen, phosphorous, organic matter.2. Nostoc and Anabaena are free living photosynthetic organisms capable of fixing atmospheric nitrogen.3. Mycorrhizal fungi acts as bio-fertliser and areknown to occur naturally on the roots of foresttrees and crop plants.Which of the statement(s) given above is/are correct?a) 1 onlyb) 1 and 2 onlyc) 2 and 3 onlyd) 1, 2 and 3

Correct.
Using Biofertilizer is one of the energy efficient and pollution free method is to exploit the ability of certain microorganisms like bacteria, algae and fungi to fix atmospheric nitrogen, solubilize phosphorus, decompose organic material or oxidize sulphur in the soil. When they are applied in the soil, they enhance growth and yield of crops, improve soil fertility and reduce pollution. Thus bio-fertilizers are living or biologically active products or microbial inoculants of bacteria, algae and fungi (separately or in combination) which are able to enrich the soil with nitrogen, phosphorus, organic matter etc.
Blue green algae (BGA or cyanobacteria) like Nostoc and Anabaena are free livingp photosyntheticorganisms also capable of fixing atmospheric nitrogen. In the flooded rice fields blue green algae serves as a nitrogen biofertilizer.
Mycorrhizal fungi acts as biofertilizer and occur naturally on roots of forest trees and crop plants. Mycorrhizal fungi are hosted by the trees in their roots to receive nutrients from the soil. These fungi provide essential nutrients like nitrogen, phosphorus and potassium from soil in exchange for carbon from the tree.
