Which of the following human activities is a major contributor to the release of greenhouse gases, a primary cause of climate change?

  1. Deforestation

  2. Industrialization

  3. Transportation

  4. Agriculture


Correct Option: B
Explanation:

Industrialization, particularly the burning of fossil fuels for energy production, is a significant source of greenhouse gas emissions, contributing to the increase in global temperatures.

What is the primary greenhouse gas emitted by human activities that contributes to global warming?

  1. Carbon Dioxide (CO2)

  2. Methane (CH4)

  3. Nitrous Oxide (N2O)

  4. Sulfur Dioxide (SO2)


Correct Option: A
Explanation:

Carbon Dioxide (CO2) is the most significant greenhouse gas emitted by human activities, primarily through the burning of fossil fuels, leading to the enhanced greenhouse effect and global warming.

Deforestation, often driven by human activities such as agriculture and urbanization, can lead to which of the following consequences?

  1. Increased Carbon Sequestration

  2. Reduced Biodiversity

  3. Enhanced Local Climate

  4. Improved Soil Fertility


Correct Option: B
Explanation:

Deforestation results in the loss of forest ecosystems, leading to reduced biodiversity, as many species rely on forests for their survival.

The burning of fossil fuels, a major human activity, releases harmful pollutants into the atmosphere. Which of these pollutants is primarily responsible for acid rain?

  1. Carbon Monoxide (CO)

  2. Nitrogen Oxides (NOx)

  3. Sulfur Dioxide (SO2)

  4. Hydrocarbons (HC)


Correct Option: C
Explanation:

Sulfur Dioxide (SO2) emitted during the burning of fossil fuels is a primary contributor to acid rain, as it reacts with water vapor in the atmosphere to form sulfuric acid.

Which human activity is a significant source of methane (CH4), a potent greenhouse gas with a global warming potential 25 times higher than carbon dioxide?

  1. Industrial Manufacturing

  2. Transportation

  3. Agriculture (Livestock)

  4. Residential Heating


Correct Option: C
Explanation:

Agriculture, particularly livestock farming, is a major source of methane emissions due to the enteric fermentation process in animals and the management of manure.

The process of converting natural ecosystems, such as forests and wetlands, into agricultural land is known as:

  1. Reforestation

  2. Deforestation

  3. Afforestation

  4. Rewilding


Correct Option: B
Explanation:

Deforestation refers to the conversion of natural ecosystems, primarily forests, into agricultural land or other non-forest uses.

Which human activity is a significant contributor to the emission of nitrous oxide (N2O), a greenhouse gas with a global warming potential 298 times higher than carbon dioxide?

  1. Industrial Processes

  2. Transportation

  3. Residential Heating

  4. Agriculture (Fertilizers)


Correct Option: D
Explanation:

Agriculture, particularly the use of nitrogen-based fertilizers, is a major source of nitrous oxide emissions due to the microbial processes involved in nitrogen cycling.

The term 'carbon footprint' refers to:

  1. The amount of carbon stored in a forest

  2. The amount of carbon dioxide released by an individual or organization

  3. The amount of carbon dioxide absorbed by a plant

  4. The amount of carbon dioxide released by a vehicle


Correct Option: B
Explanation:

Carbon footprint refers to the total amount of greenhouse gases produced to directly and indirectly support human activities, usually expressed in equivalent tons of carbon dioxide (CO2e).

Which of the following human activities is a major contributor to the release of black carbon, a type of particulate matter that can have significant climate and health impacts?

  1. Industrial Manufacturing

  2. Transportation (Diesel Engines)

  3. Residential Heating (Wood Burning)

  4. Agriculture (Crop Burning)


Correct Option: B
Explanation:

Transportation, particularly diesel engines in vehicles, is a major source of black carbon emissions due to incomplete combustion of fuel.

The process of capturing and storing carbon dioxide from the atmosphere or industrial sources to reduce its impact on the climate is known as:

  1. Carbon Sequestration

  2. Carbon Capture and Storage (CCS)

  3. Carbon Offsetting

  4. Carbon Pricing


Correct Option: B
Explanation:

Carbon Capture and Storage (CCS) involves capturing carbon dioxide from industrial sources or the atmosphere and storing it underground or in geological formations to prevent its release into the atmosphere.

Which human activity is a significant contributor to the emission of hydrofluorocarbons (HFCs), potent greenhouse gases with high global warming potentials?

  1. Industrial Refrigeration and Air Conditioning

  2. Transportation

  3. Agriculture

  4. Residential Heating


Correct Option: A
Explanation:

Industrial refrigeration and air conditioning systems are major sources of HFC emissions due to their use as refrigerants.

The term 'climate change' refers to:

  1. Short-term fluctuations in weather patterns

  2. Long-term shifts in temperature and precipitation patterns

  3. Seasonal variations in climate

  4. Extreme weather events


Correct Option: B
Explanation:

Climate change refers to long-term shifts in temperature and precipitation patterns, often attributed to human activities and the increase in greenhouse gas concentrations in the atmosphere.

Which human activity is a significant contributor to the emission of sulfur hexafluoride (SF6), a potent greenhouse gas with a global warming potential 23,900 times higher than carbon dioxide?

  1. Industrial Processes (Electrical Equipment)

  2. Transportation

  3. Agriculture

  4. Residential Heating


Correct Option: A
Explanation:

Industrial processes, particularly the production and use of electrical equipment, are major sources of SF6 emissions.

The term 'global warming' refers to:

  1. The increase in average global temperatures

  2. The rise in sea levels

  3. The melting of glaciers and ice caps

  4. The increase in extreme weather events


Correct Option: A
Explanation:

Global warming refers to the long-term increase in Earth's average surface temperature, primarily due to the accumulation of greenhouse gases in the atmosphere.

Which human activity is a significant contributor to the emission of perfluorocarbons (PFCs), potent greenhouse gases with high global warming potentials?

  1. Industrial Processes (Aluminum Production)

  2. Transportation

  3. Agriculture

  4. Residential Heating


Correct Option: A
Explanation:

Industrial processes, particularly aluminum production, are major sources of PFC emissions.
