Q 01. Global climates are classified on the basis of:(UPSC-Geologist-2020)
- annual averages in temperature and precipitation only.
- annual averages in temperature only.
- seasonal variations in temperature and precipitation only.
- annual averages and seasonal variations in temperature and precipitation.
- The most widely used classification of climate is the empirical climate classification scheme developed by V. Koeppen.
- Koeppen identified a close relationship between the distribution of vegetation and climate.
- He selected certain values of temperature and precipitation and related them to the distribution of vegetation and used these values for classifying the climates.
- This classification based on average annual and average monthly temperature and precipitation data.
- Koeppen recognised five major climatic groups, four of them are based on temperature and one on precipitation.
|A – Tropical||Average temperature of the coldest month is 18° C or higher|
|B – Dry Climates||Potential evaporation exceeds precipitation|
|C – Warm Temperate||The average temperature of the coldest month of the (Mid-latitude) climates years is higher than minus 3°C but below 18°C|
|D – Cold Snow Forest Climates||The average temperature of the coldest month is minus 3° C or below|
|E – Cold Climates||Average temperature for all months is below 10° C|
|H – HighLand||Cold due to elevation|

- Sambhar Salt Lake, India’s largest inland salt lake, is located 80 km southwest of the city of Jaipur, Rajasthan, surrounded by the Aravali hills on all sides.
- 1990L Sambhar designated as a Ramsar wetland site since it is a key wintering area for tens of thousands of pink flamingos and other birds that migrate from northern Asia and Siberia.
- Avian botulism is caused by the soil bacterium, Clostridium botulinum, and causes paralysis and death in birds.Avian botulism has been recognised as a major cause of mortality in wild-birds since the 1900s.
- Humans can become sick from botulism typically by eating improperly canned or stored foods. Aside from this, humans and pets are primarily at risk only if they eat infected fish, birds or maggots.

|Bryophyta||liverworts, hornworts and mosses. They are characteristically limited in size and prefer moist habitats|
|Pteridophyta||They produce neither flowers nor seeds. They reproduce through spores dispersion.|
|Angiosperms||While they have stems, roots, and leaves. Unlike gymnosperms such as conifers, the angiosperm’s seeds are found in a flower.|

(a) availability of water in their habitat.
(b) size of their mouth cavity.
(c) kind of habitats where they live.
(d) kind of food they eat:
- Cows (Herbivores) eat only plants. Plants contain cellulose which requires a longer time for digestion.
- Tigers are carnivores. They eat only meat and flesh which can be digested in a comparatively shorter period.
- Hence the small intestine of a tiger is shorter than that of a cow’s small intestine.

(a) Flood Control Management (FCM)
(b) Solid Waste Management (SWM)
(c) Integrated Coastal Zone Management (ICZM)
(d) Natural Ecosystem Zone (NEZ)
- FCM will only reduce impact of disasters and SWM will reduce the impact of pollution,
- But by themselves, they’ll not help greatly in achieving sustainable development as compared to Integrated Coastal Zone Management (ICZM)
- Based on the recommendations of the expert committee report of the Prof M. S. Swaminathan, the Ministry of Environment and Forests (MoEF) is making efforts to implement an Integrated Coastal Zone Management (ICZM) Plan for India instead of a uniform Coastal Regulatory Zone (CRZ) framework.
- The MOEF has Launched the Integrated Coastal Zone Management project by establishing a Society of Integrated Coastal Management. (SICOM)
Under the project, SICOM would be implementing the four components as follows:
- National Coastal Management Programme
- ICZM-West Bengal
- ICZM helps in long term and sustained to use coastal natural resources and maintenance of the natural ecosystem.
Q 05. Climate Vulnerability Index Reflect Situation for,

- 12 Satte are Assam, Manipur, Meghalaya, Mizoram, Nagaland, Tripura, Arunachal Pradesh, Sikkim, West Bengal, Himachal Pradesh, Uttarakhand and Jammu and Kashmir.
- Assam and Mizoram are Most Vulnerable States in this Report.
- The vulnerability score was calculated based on eight parameters such as percentage of area in districts under forests, yield variability of food grain, population density, female literacy rate, infant mortality rate, percentage of population below poverty line (BPL), average man-days under MGNREGA (Mahatma Gandhi National Rural Employment Guarantee Act), and the area under slope > 30%.
Q. Which of the following practices are adopted for river basin water resources management? (UPSC-IES-2020)
1. Soil conservation in catchments of river valley projects and flood-prone rivers
2. Soil and land use surveys
3. Control of shifting cultivation
(a) 1, 2 and 4
(b) 1, 3 and 4
(c) 2, 3 and 4
(d) 1, 2 and 3
- Deforestation can’t be “practice adopted” in river basin water resources management, infact has to be ‘practice discouraged/reduced’. So go by elimination method.
Q. Which one of the following gases is colourless with strong odour, irritates mucous membranes at common levels, can cause cough, fatigue and interference with lung functions at higher concentration? (UPSC-IES-2020)
(a) Carbon monoxide
- Here we shall focus the word in question colourless with strong odour.
- Here all the gases are colourless but when we check strong odour – it’s Ozone.
- Ozone irritates the mucous membranes of the nose, throat and airways
- 1987: Montreal Protocol designed to stop the production and import of ozone depleting substances and reduce their concentration in the atmosphere to help protect the earth’s ozone layer.
- It outlawed CFCs and HCFCs.
- But then industries started using HFCs as replacements.
- While Hydrofluorocarbons (HFCs) may not harm Ozone layer but they’re greenhouses gases responsible for globalwarming so,
- 2016: Kigali Agreement (capital city of Rwanda) aims to phase out Hydrofluorocarbons (HFCs) by mid-2040s.
Q. Which of the following are the suggested ways of reducing NOx emissions from stationary sources? (UPSC-IES-2020)
1. By reducing the peak temperature.
2. By increasing the availability of N2 for reaction with O2.
3. By minimizing the availability of O2 for reaction with N2.
(a) 1 and 2 only
(b) 1 and 3 only
(c) 2 and 3 only
(d) 1, 2 and 3
- NOx gases are usually produced from the reaction among nitrogen and oxygen during combustion of fuels, such as hydrocarbons. So, if #2 is done (increasing the availability of N2 for reaction with O2.) then it’ll further increase NoX emission. So go by elimination method!
Q. Which one of the following is a hygienic way of disposing solid waste and is more suitable if the waste contains more hazardous material and organic content? (UPSC-IES-2020)
- Focus on words of hazardous material and organic content.
- First option Composting is not possible due to Hazardous Word.
- Option (c) Oxidation and Option (d) Subgrading is not suitable for hazardous material and organic content.
- Incineration is burning the waste under controlled conditions. Here, pathogens and toxins can be destroyed by high temperatures, so it’s more suitable among the given options.
- Waste management in India falls under the purview of the Union Ministry of Environment, Forests and Climate Change (MoEF&CC).
- 2016 this ministry released the Solid Waste Management (SWM) Rules, 2016 to replace Municipal Solid Wastes (Management and Handling) Rules, 2000
Q. NEPA stands for: (UPSC-IES-2020)

- more than 100 nations around the world have enacted national environmental policies modeled after NEPA.
Q. Basel Convention provides: (UPSC-IES-2020)
(a) Indian standards for pollution measurement and prevention
(b) International guidelines to control the transboundary movements of hazardous wastes between different countries
(c) Indian standards for the disposal of municipal and industrial wastes
(d) International standards to categorize pollution in air and wastewater
- 1989: United Nations’ Basel Convention: Prohibiting Trans bountrieng Moments of Hazardous Waste
- 2019: more reforms under. Now BASEL prohibits export of hazardous wastes from member states of the European Union, Organization for Economic Cooperation and Development (OECD), and Liechtenstein to all other countries.
