Factors Influencing Global Temperature Change

Which natural factor can change global temperatures over thousands of years?

• Deforestation

• Volcanic eruptions

• Industrial emissions

• Urbanization

How do greenhouse gases affect Earth's temperature?

• They reflect sunlight away.

• They trap heat.

• They absorb sunlight and cool Earth.

• They increase Earth's albedo.

Which greenhouse gas is most linked to human activities?

What is the main source of carbon dioxide emissions causing global warming?

• Volcanic eruptions

• Burning fossil fuels

• Photosynthesis

• Ocean currents

What is an effect of more greenhouse gases?

• Lower sea levels

• Higher global temperatures

• Frequent volcanic eruptions

• Less solar radiation

Which activity significantly increases methane in the atmosphere?

• Deforestation

• Rice cultivation

• Solar panel installation

• Wind energy production

What is the role of oceans in Earth's climate?

• They absorb and store carbon dioxide.

• They increase Earth's albedo.

• They emit greenhouse gases.

• They reflect sunlight.

What is a result of global warming?

• Less plant growth

• More ice sheets

• Higher sea levels

• Stable weather

How does deforestation affect global warming?

• By increasing Earth's albedo

• By reducing carbon dioxide absorption by trees

• By increasing volcanic activity

• By decreasing methane emissions

What is a long-term effect of increased greenhouse gases?

• Shorter growing seasons

• Increased frequency of solar eclipses

• More intense and frequent heatwaves

• Decreased ocean acidity
