Which of the following is NOT a greenhouse gas?

  1. Carbon Dioxide (CO2)

  2. Oxygen (O2)

  3. Methane (CH4)

  4. Water Vapor (H2O)


Correct Option: B
Explanation:

Oxygen is not a greenhouse gas because it does not absorb and trap heat in the atmosphere like other greenhouse gases such as CO2, CH4, and H2O.

What is the main driver of climate change?

  1. Solar Radiation

  2. Volcanic Eruptions

  3. Human Activities

  4. Ocean Currents


Correct Option: C
Explanation:

Human activities, particularly the burning of fossil fuels, are the primary cause of climate change. These activities release greenhouse gases into the atmosphere, leading to an increase in global temperatures.

What is the term used to describe the long-term average of weather conditions in a particular area?

  1. Climate

  2. Weather

  3. Atmosphere

  4. Biosphere


Correct Option: A
Explanation:

Climate refers to the long-term average of weather conditions, including temperature, precipitation, wind patterns, and humidity, in a specific region over an extended period.

Which of the following is a consequence of rising sea levels due to climate change?

  1. Increased Coastal Erosion

  2. Reduced Biodiversity

  3. More Frequent Droughts

  4. Decreased Storm Intensity


Correct Option: A
Explanation:

Rising sea levels can lead to increased coastal erosion, as higher water levels cause waves to reach further inland and erode shorelines.

What is the term used to describe the process by which plants absorb carbon dioxide from the atmosphere during photosynthesis?

  1. Carbon Sequestration

  2. Carbon Capture

  3. Carbon Fixation

  4. Carbon Storage


Correct Option: C
Explanation:

Carbon fixation is the process by which plants, algae, and some bacteria convert carbon dioxide into organic compounds during photosynthesis.

Which of the following is a renewable energy source?

  1. Fossil Fuels

  2. Nuclear Energy

  3. Hydropower

  4. Natural Gas


Correct Option: C
Explanation:

Hydropower is a renewable energy source that generates electricity from the energy of flowing water.

What is the term used to describe the phenomenon where the Earth's surface absorbs more heat than it reflects?

  1. Albedo

  2. Greenhouse Effect

  3. Global Warming

  4. Climate Change


Correct Option: A
Explanation:

Albedo refers to the fraction of solar radiation reflected by the Earth's surface back into space. A lower albedo means more heat is absorbed by the Earth's surface, contributing to global warming.

Which of the following is a type of cloud that is associated with thunderstorms?

  1. Cumulus

  2. Stratus

  3. Cirrus

  4. Nimbostratus


Correct Option: D
Explanation:

Nimbostratus clouds are thick, dark gray clouds that often bring steady precipitation and are associated with thunderstorms.

What is the term used to describe the process by which heat is transferred from the Earth's surface to the atmosphere?

  1. Convection

  2. Conduction

  3. Radiation

  4. Advection


Correct Option: A
Explanation:

Convection is the process by which heat is transferred from the Earth's surface to the atmosphere through the movement of air currents.

Which of the following is a type of climate model used to predict future climate conditions?

  1. General Circulation Model (GCM)

  2. Regional Climate Model (RCM)

  3. Earth System Model (ESM)

  4. Ocean-Atmosphere Model (OAM)


Correct Option: A
Explanation:

General Circulation Models (GCMs) are computer models that simulate the Earth's climate system and are used to predict future climate conditions.

What is the term used to describe the process by which the Earth's climate system returns to its equilibrium state after a disturbance?

  1. Climate Feedback

  2. Climate Variability

  3. Climate Sensitivity

  4. Climate Resilience


Correct Option: A
Explanation:

Climate feedback refers to the process by which the Earth's climate system responds to a change in external forcing, such as an increase in greenhouse gas concentrations.

Which of the following is a type of natural climate variability that occurs in the Pacific Ocean?

  1. El Niño-Southern Oscillation (ENSO)

  2. North Atlantic Oscillation (NAO)

  3. Indian Ocean Dipole (IOD)

  4. Pacific Decadal Oscillation (PDO)


Correct Option: A
Explanation:

El Niño-Southern Oscillation (ENSO) is a type of natural climate variability that occurs in the Pacific Ocean and affects global weather patterns.

What is the term used to describe the process by which the Earth's climate system adjusts to long-term changes in external forcing?

  1. Climate Adaptation

  2. Climate Mitigation

  3. Climate Resilience

  4. Climate Stabilization


Correct Option: A
Explanation:

Climate adaptation refers to the process by which societies and ecosystems adjust to the impacts of climate change.

Which of the following is a type of geoengineering technique proposed to mitigate climate change?

  1. Carbon Capture and Storage (CCS)

  2. Solar Radiation Management (SRM)

  3. Weather Modification

  4. Ocean Fertilization


Correct Option: A
Explanation:

Carbon Capture and Storage (CCS) is a geoengineering technique that involves capturing carbon dioxide from industrial sources and storing it underground.

What is the term used to describe the process by which the Earth's climate system reaches a new equilibrium state after a change in external forcing?

  1. Climate Stabilization

  2. Climate Mitigation

  3. Climate Resilience

  4. Climate Adaptation


Correct Option: A
Explanation:

Climate stabilization refers to the process by which the Earth's climate system reaches a new equilibrium state after a change in external forcing, such as a reduction in greenhouse gas emissions.
