• Planting trees

• I don’t know yet

What is the impact of deforestation on the greenhouse effect?

• Decreases CO2 in the atmosphere

• Increases oxygen levels

• Raises atmospheric CO2 levels

• I don’t know yet

Which gas is increasing in the atmosphere due to both agriculture and waste treatment?

• CO2

• O2

• CH4

• I don’t know yet

How does deforestation primarily affect greenhouse gas levels?

• By reducing CH4 emissions

• By increasing available oxygen

• By adding more CO2 to the atmosphere

• I don’t know yet

What role does methane (CH4) play in the greenhouse effect?

• It cools the atmosphere

• It has no effect

• It traps heat more effectively than CO2

• I don’t know yet

Why is the enhanced greenhouse effect a concern?

• It decreases global temperatures

• It disrupts natural climate patterns

• It reduces CO2 in the atmosphere

• I don’t know yet

Which greenhouse gas is most abundant in Earth's atmosphere?

• Methane (CH4)

• Carbon dioxide (CO2)

• Nitrous oxide (N2O)

• I don't know yet

How do human activities enhance the greenhouse effect?

• By increasing the albedo effect

• By increasing the levels of greenhouse gases

• By decreasing the Earth's temperature

• I don't know yet

What is the consequence of the enhanced greenhouse effect on weather patterns?

• It makes them more predictable

• It has no significant impact

• It can lead to more extreme weather events

• I don't know yet

Which human activity contributes to rising methane levels?

• Wind power generation

• Increased use of electric cars

• Livestock farming and waste management
