Question : The concept of "carbon sequestration" refers to:
Option 1: The process of capturing and storing carbon dioxide
Option 2: The release of carbon dioxide into the atmosphere
Option 3: The conversion of carbon dioxide into oxygen
Option 4: The absorption of carbon dioxide by plants
Correct Answer: The process of capturing and storing carbon dioxide
Solution : The correct answer is (A) The process of capturing and storing carbon dioxide
The concept of "carbon sequestration" refers to the process of capturing carbon dioxide (CO2) from the atmosphere or other sources and storing it in a way that prevents its release back into the atmosphere. This process helps to mitigate climate change by reducing the concentration of greenhouse gases, specifically CO2, in the atmosphere.
Carbon sequestration can occur naturally through processes such as photosynthesis, where plants absorb CO2 and store carbon in their tissues. It can also be achieved through technological methods, such as carbon capture and storage (CCS), where CO2 emissions from power plants or industrial processes are captured and stored underground or in other long-term storage facilities.
The goal of carbon sequestration is to reduce the amount of CO2 in the atmosphere, as it is a major contributor to global warming and climate change. By capturing and storing carbon dioxide, it helps to mitigate the impacts of greenhouse gas emissions and work towards a more sustainable and low-carbon future.
Question : The term "carbon offsetting" refers to:
Option 1: Reducing carbon emissions through technological advancements
Option 2: Investing in renewable energy projects to compensate for carbon emissions
Option 3: Capturing and storing carbon dioxide underground
Option 4: Using carbon capture and storage (CCS) technology in power plants
Question : The concept of "carbon footprint" refers to:
Option 1: The total emissions of greenhouse gases by a country
Option 2: The impact of carbon dioxide on human health
Option 3: The amount of carbon stored in forests
Option 4: The carbon content in fossil fuels
Option 1: The total amount of carbon dioxide emitted by a person, organization, or activity
Option 2: The amount of carbon stored in a forest
Option 3: The distance traveled by a vehicle
Option 4: The carbon emissions from a power plant
