Weekly Quiz Competition

Question 1
1 / -0

Which one of the following is the best source of generating electricity in India from the viewpoint of sustainable development?

A
Coal

B
Mineral oil and gas

C
Hydro electricity

D
Atomic energy

Solution

Hydroelectricity is the most sustainable method of generating electricity among the four alternatives. Hydropower is the world's largest source of renewable energy and produces negligible amounts of greenhouse gases and played an important role in world's dependency on fossil fuels.
Question 2
1 / -0

Eutrophication in the Chesapeake Bay along the eastern edge of Mary land has resulted in low oxygen levels in the water and alternation of food webs. The cause of this eutrophication appears to be pollution that contains high levels of:

A
nitrogen and carbon

B
nitrogen and phosphorus

C
carbon and phosphorus

D
carbon, nitrogen and phosphorus
Question 3
1 / -0

What is the carbon credit?

A
It is the difference between the carbon emission allowed and actually emitted carbon

B
It is the loan amount by IMF for reducing pollution

C
It is loan given to poor people for buying Modern Stoves

D
All of the above
Question 4
1 / -0

Relative contributions of $$ CO_{2}, CH_{4}, CFCs$$ and $$ N_{2}O$$ towards global warning are:

A
50%, 30%, 10%, and 10% respectively

B
60%, 20%, 14%, and 6% respectively

C
40%, 30%, 20%, and 10% respectively

D
None of the above
Question 5
1 / -0

The minimum area of the land required to completely sustain the life of one person is called his

A
Biota

B
Biome

C
Ecological foot print

D
Niche

Solution

Ecological footprint is the minimum area of land which is required to completely sustain the life on an individual or a population. It actually measures the demands made by a person or group of people on global natural resources.
Question 6
1 / -0

The Delhi Metro is the first ever railway system in the world to be awarded with the prestigious Gold Standard Foundation (GSF) certification standard for

A
providing security to the people

B
using the energy efficiently

C
carrying largest number of passengers

D
All of the above

Solution

GSF standard certification is a globally accepted certifiaction standard for carbon mitigation projects. The Delhi Metro Rail Corporation (DMRC) registered for the certification standard for its energy efficiency measures undertaken in 51 stations in phase II of the DMRC project. The energy efficiency measures were primarily undertaken in the heating. venting and air conditioning (HVAC) systems. lighting system and other energy efficient measures of station buildings; the measures adopted in the HVAC system resulted in reduction in electrical
energy consumption
Question 7
1 / -0

Earth summit was held in

A
Chicago

B
Copenhagen

C
Rio de Janeiro

D
London

Solution

The Earth Summit or UN Conference on Environment and Development (UNCED) was held in Rio de Janeiro during 3-14 June 1992.

G.B. Pant Institute of Himalayan Environment and Development (GBPIHED) released the Report titled "Estimation of retreat of Gangotri glacier" on 7 January 2014. The Report includes-
1. Gangotri glacier is retreating in the Himalayas and its volume and size are shrinking between Gaumukh and Bhojbasa.
2. There is some disintegration in the upper regions of the Gangotri glaciers due to tectonic activities.
3. Retreat of Gangotri glaciers in this decade was higher than in previous decade due to global warning.

All of the above
Question 9
1 / -0

In the context of mitigating the impending global warning due to anthropogenic emissions of carbon dioxide. which of the following can be the potential sites for carbon sequestration?
1. Abandoned and uneconomic coal seams
2. Depleted oil and gas reservoirs
3. Subterranean deep saline formations
Select the correct answer using the code given below:

A
1 and 2 only

B
3 only

C
1 and 3 only

D
1, 2 and 3

Solution

Carbon sequestration may be carried out by pumping carbon into carbon sinks of two types:
A. Natural sinks-ocean, forest, soil etc.
B. Artificial sink-depleted oil reserve, unminable mines. So statement 1 and 2 are correct.
And deep Saline Formations infact have highest capacity for this.So accordingly, answer is "D".
Question 10
1 / -0

Consider the following statements:
1. Climate and Clean Air Coalition (CCAC) to reduce Short Lived Climate Pollutants is a unique initiative of G20 group of countries.
2. The CCAC focuses on methane, black carbon and hydrofluorocarbons.
Which of the statements given above is/ are correct?

A
1 only

B
2 only

C
Both 1 and 2

D
Neither 1 nor 2

Solution

As per the timeline given on their official "About us" page : CCAC was formed in 2012 by UNEP and Ghana, Bangladesh etc. countries. So first statement is wrong. Second statement is right-they focus on Short Lived Climate Pollutants such as methane, black carbon and hydrofluorocarbons.
