What is the primary greenhouse gas responsible for global warming?

  1. Carbon Dioxide (CO2)

  2. Methane (CH4)

  3. Nitrous Oxide (N2O)

  4. Water Vapor (H2O)


Correct Option: A
Explanation:

Carbon Dioxide (CO2) is the primary greenhouse gas responsible for global warming. It is released into the atmosphere through human activities such as burning fossil fuels and deforestation.

What is the term used to describe the gradual increase in the Earth's average temperature?

  1. Global Warming

  2. Climate Change

  3. Greenhouse Effect

  4. Ozone Depletion


Correct Option: A
Explanation:

Global Warming refers to the gradual increase in the Earth's average temperature due to the accumulation of greenhouse gases in the atmosphere.

Which human activity is a major contributor to air pollution?

  1. Driving Cars

  2. Using Electricity

  3. Recycling Waste

  4. Planting Trees


Correct Option: A
Explanation:

Driving cars, particularly those powered by fossil fuels, releases harmful pollutants such as carbon monoxide, nitrogen oxides, and particulate matter into the air.

What is the process by which harmful substances are removed from the environment?

  1. Bioremediation

  2. Phytoremediation

  3. Georemediation

  4. Ex situ Remediation


Correct Option: A
Explanation:

Bioremediation is the process of using microorganisms to break down and remove harmful substances from the environment.

Which of the following is a renewable source of energy?

  1. Solar Energy

  2. Wind Energy

  3. Hydropower

  4. Natural Gas


Correct Option: A
Explanation:

Solar Energy is a renewable source of energy that is generated from the sun's rays.

What is the term used to describe the loss of biodiversity?

  1. Habitat Fragmentation

  2. Extinction

  3. Endangered Species

  4. Invasive Species


Correct Option: B
Explanation:

Extinction refers to the complete disappearance of a species from the Earth.

Which human activity is a major contributor to deforestation?

  1. Agriculture

  2. Mining

  3. Urbanization

  4. Reforestation


Correct Option: A
Explanation:

Agriculture, particularly large-scale farming, is a major contributor to deforestation as forests are cleared to make way for crops and livestock.

What is the term used to describe the process of restoring degraded ecosystems?

  1. Reforestation

  2. Afforestation

  3. Habitat Restoration

  4. Ecological Restoration


Correct Option: D
Explanation:

Ecological Restoration refers to the process of restoring degraded ecosystems to their natural state.

Which of the following is a major cause of water pollution?

  1. Industrial Waste

  2. Agricultural Runoff

  3. Sewage Discharge

  4. Oil Spills


Correct Option: B
Explanation:

Agricultural Runoff, containing fertilizers and pesticides, is a major cause of water pollution as it can contaminate rivers, lakes, and groundwater.

What is the term used to describe the process of reducing greenhouse gas emissions?

  1. Carbon Capture and Storage

  2. Renewable Energy Transition

  3. Energy Efficiency

  4. Afforestation


Correct Option: A
Explanation:

Carbon Capture and Storage involves capturing carbon dioxide from industrial sources and storing it underground to prevent its release into the atmosphere.

Which of the following is a major cause of soil degradation?

  1. Erosion

  2. Salinization

  3. Desertification

  4. Acidification


Correct Option: A
Explanation:

Erosion, caused by factors such as wind and water, is a major cause of soil degradation as it removes the fertile topsoil.

What is the term used to describe the process of reducing waste generation?

  1. Recycling

  2. Composting

  3. Waste Reduction

  4. Zero Waste


Correct Option: C
Explanation:

Waste Reduction refers to the practice of reducing the amount of waste produced at the source.

Which of the following is a major cause of marine pollution?

  1. Plastic Waste

  2. Oil Spills

  3. Sewage Discharge

  4. Agricultural Runoff


Correct Option: A
Explanation:

Plastic Waste, particularly single-use plastics, is a major cause of marine pollution as it can accumulate in oceans and harm marine life.

What is the term used to describe the process of protecting and managing natural resources?

  1. Conservation

  2. Preservation

  3. Restoration

  4. Sustainability


Correct Option: A
Explanation:

Conservation refers to the practice of protecting and managing natural resources to ensure their long-term availability.

Which of the following is a major cause of air pollution in urban areas?

  1. Vehicle Emissions

  2. Industrial Emissions

  3. Power Plants

  4. Construction Activities


Correct Option: A
Explanation:

Vehicle Emissions, particularly from cars and trucks, are a major cause of air pollution in urban areas as they release harmful pollutants such as nitrogen oxides and particulate matter.
