Question 1 of 5
1. Question
Carbon Capture Utilization Storage (CCUS) is the process of
Correct
Solution: a)
Carbon capture utilization storage is the process of capturing waste carbon dioxide (CO2) from large point sources, such as fossil fuel power plants, and either transporting it to a storage site where it will not enter the atmosphere, normally an underground geological formation, or reusing it.
In Carbon Capture and Storage (CCS), emissions are forced into underground rocks at great cost and no economic benefit while CCUS aims at using CO2 emissions by exploiting the resource itself and creating new markets around it.

Question 2 of 5
2. Question
Which of the following are the Geoengineering techniques designed to tackle the effects of climate change?
- Artificial treesthat pull the CO2 from the atmosphere using plastic polymers.
- Adding large quantities of lime to the Ocean water to increase the amount of CO2 absorption by the oceans.
- Using unmanned ships to increase above-ocean cloud cover by spraying sea water into the air.
- Floating thousands of tiny mirrors in space between Earth and the sun.
Select the correct answer code:
Correct
Solution: d)
Geoengineering schemes are projects designed to tackle the effects of climate change directly, usually by removing CO2 from the air or limiting the amount of sunlight reaching the planet’s surface.
The first category of scheme – those designed to remove CO2 from the air – include machines (sometimes called “artificial trees”) that pull the gas from the atmosphere using plastic polymers. Other proposals seek to increase the amount of CO2 absorbed by the oceans – for example by adding large quantities of lime to the water.
In the second category – schemes designed to reduce the amount of sunlight reaching Earth – proposals include firing sulphate aerosols into the stratosphere to reflect sunlight back to space; using unmanned ships to increase above-ocean cloud cover by spraying sea water into the air; painting the world’s roofs white to increase reflectivity; and even floating thousands of tiny mirrors in space between Earth and the sun.

Question 3 of 5
3. Question
Which of the following clearly shows the importance of carbon dioxide in earth’s atmosphere?
- It is essential for the growth of plants.
- It is the most abundant gas in the atmosphere after nitrogen and oxygen.
- It absorbs the heat directly incoming from the Sun thus warming the planet.
Select the correct answer code:
Correct
Solution: a)
Statement 1: Green plants use CO2 gas to prepare their food through photosynthesis.
Statement 2: Argon is the next abundant gas.
Statement 3: Carbon dioxide in the atmosphere does not absorb the incoming visible radiations coming from the sun, but Carbon dioxide blocks the out going infrared radiations radiated by earth. By absorbing infrared radiations, the atmosphere gets heated. This is known as Green house Effect. The heated atmosphere keeps the earthworm. Thus carbon dioxide helps in keeping the earth warmer by blocking the infrared radiations.

Question 4 of 5
4. Question
Ocean acts as a large carbon sink on earth due to
Correct
Solution: d)
Oceans are one of the largest carbon sinks on earth because of their large geographical coverage and presence of rich population of phytoplankton and seagrass, which act as carbon sink.
Carbon dioxide readily dissolves in water and the oceans provide a huge reservoir of carbon. Across the world’s oceans there is a continual cycle of equilibration of dissolved carbon dioxide in water with carbon dioxide in the atmosphere.
The difference in partial pressure of the CO2 between seawater and air facilitate gaseous exchange. This allows atmospheric CO2 to dissolve in seawater.
The carbon dioxide which dissolves in our oceans occurs in three main forms. Aside from the normal carbon dioxide form, it is also found as bicarbonate and carbonate ions.

Question 5 of 5
5. Question
Consider the following statements.
- Carbon neutrality refers to achieving net zero carbon dioxide emissions.
- Carbon neutrality can be achieved only by eliminating carbon dioxide emissions altogether.
- Renewable energy always produce zero carbon emissions.
Which of the above statements is/are correct?
Correct
Solution: a)
Carbon neutrality refers to achieving net zero carbon dioxide emissions by balancing carbon dioxide emissions with removal (often through carbon offsetting) or simply eliminating carbon dioxide emissions altogether (the transition to the “post-carbon economy”).
Although both renewable and non-renewable energy both produce carbon emissions in some form, renewable energy has a lesser to almost zero carbon emissions.
