Revision IA1 Part 1

What is the first step in the sequence leading to climate change as mentioned in the image?

• Enhanced greenhouse effect

• Increased CO2 release

• Tree cover loss

• Climate change

What is the ultimate environmental impact of tree cover loss and land clearing?

• Soil erosion

• Climate change

• Water pollution

• Air quality improvement

What is the role of longwave radiation in the greenhouse effect?

• It cools the Earth's surface.

• It is absorbed by greenhouse gases, warming the atmosphere.

• It is reflected back into space.

• It is used in photosynthesis.

What is the impact of additional greenhouse gases in the enhanced greenhouse effect?

• They decrease Earth's temperature.

• They increase Earth's temperature.

• They have no impact on Earth's temperature.

• They decrease solar radiation.

What is the primary source of radiation in the greenhouse effect?

• Moonlight

• Solar radiation

• Starlight

• Earth's core

What is the significance of the natural greenhouse effect?

• It has no impact on life

• It makes the planet uninhabitable

• It makes the planet habitable

• It decreases biodiversity

What is the consequence of increased CO2 concentrations in the atmosphere?

• Enhanced greenhouse effect

• Decreased global temperatures

• Increased biodiversity

• Reduced air pollution

What happens to the natural biodiversity of the forest when it is cleared?

• It increases

• It remains the same

• It is replaced by a monoculture

• It becomes more diverse

What is the impact of the enhanced greenhouse effect mentioned in the text?

• Cooling of the climate

• Warming of the climate

• Stabilization of the climate

• No impact on the climate

How is carbon sequestered in the natural carbon cycle?

• Through the burning of fossil fuels

• Through photosynthesis

• Through industrial processes

• Through animal respiration
