Environmental Challenges

What is the main greenhouse gas responsible for climate change?

• Carbon dioxide (CO2)

• Oxygen

• Nitrogen

• Methane

Answer explanation

The main greenhouse gas responsible for climate change is Carbon dioxide (CO2).

How does deforestation contribute to climate change?

• Deforestation has no impact on the environment

• Deforestation leads to an increase in oxygen levels in the atmosphere

• Deforestation reduces the number of trees that can absorb carbon dioxide.

• Deforestation increases the number of trees that absorb carbon dioxide, reducing greenhouse gases

Answer explanation

Deforestation reduces the number of trees that can absorb carbon dioxide, leading to an increase in greenhouse gases in the atmosphere.

What is the primary cause of the rising sea levels?

• Volcanic activity

• Deforestation

• Solar flares

• Melting of glaciers and ice caps

Answer explanation

The primary cause of the rising sea levels is the melting of glaciers and ice caps, leading to an increase in the volume of water in the oceans.

What is the significance of the Paris Agreement in combating climate change?

• The Paris Agreement encourages countries to increase greenhouse gas emissions

• The Paris Agreement aims to limit global warming to well below 2 degrees Celsius.

• The Paris Agreement focuses on promoting fossil fuel consumption

• The Paris Agreement has no impact on global warming

Answer explanation

The Paris Agreement aims to limit global warming to well below 2 degrees Celsius and encourages countries to set and update their own climate targets.

How do fossil fuels impact the environment in terms of climate change?

• Fossil fuels contribute to climate change by releasing carbon dioxide.

• Fossil fuels promote environmental sustainability

• Fossil fuels have no impact on climate change

• Fossil fuels reduce greenhouse gas emissions

Answer explanation

Fossil fuels contribute to climate change by releasing greenhouse gases like carbon dioxide.

What are some renewable energy sources that can help reduce carbon emissions?

• Coal power, nuclear power

• Hydropower, geothermal energy

• Oil power, peat

• petrol power, gas

Answer explanation

Renewable energy sources such as solar power, wind power, hydropower, and geothermal energy can help reduce carbon emissions by providing clean and sustainable alternatives to fossil fuels.

Explain the concept of carbon footprint and its relation to climate change.

• Carbon footprint is the total amount of greenhouse gases emitted by human activities, directly or indirectly, which contribute to climate change by trapping heat in the atmosphere.

• Carbon footprint is the measure of how many trees are planted to offset greenhouse gas emissions.

• Carbon footprint is the amount of oxygen released by human activities, which cools the atmosphere.

• Carbon footprint refers to the weight of carbon dioxide in the atmosphere, which has no impact on climate change.

Answer explanation

Carbon footprint is the total amount of greenhouse gases emitted by human activities, directly or indirectly, which contribute to climate change by trapping heat in the atmosphere.

What role do oceans play in regulating the Earth's climate?

• Oceans release carbon dioxide into the atmosphere

• Oceans cause extreme weather patterns

• Oceans play no role in regulating the Earth's climate

• Oceans regulate the Earth's climate by absorbing heat, distributing it through currents, influencing weather patterns, and absorbing carbon dioxide.

Answer explanation

Oceans regulate the Earth's climate by absorbing heat, distributing it through currents, influencing weather patterns, and absorbing carbon dioxide.

How does climate change affect biodiversity?

• Climate change has no impact on biodiversity

• Climate change leads to a decrease in biodiversity

• Biodiversity benefits from climate change

• Climate change affects biodiversity by altering habitats, disrupting ecosystems, and changing the distribution of species.

Answer explanation

Climate change affects biodiversity by altering habitats, disrupting ecosystems, and changing the distribution of species.

What are some ways individuals can reduce their carbon footprint in daily life?

• Using public transportation, biking or walking instead of driving, reducing energy consumption, recycling and composting, supporting sustainable products

• Throwing recyclables in the trash

• Leaving lights on when not in use

• Using private jets for travel

Answer explanation

Using public transportation, biking or walking instead of driving, reducing energy consumption, recycling and composting, supporting sustainable products are effective ways to reduce carbon footprint.
