  • Q4
    What is one negative impact of deforestation on climate?
    Increased biodiversity
    Improved air quality
    Decreased soil erosion
    Increased greenhouse gas emissions
    30s
  • Q5
    How does deforestation contribute to climate change?
    It lowers global temperatures
    It creates more oxygen in the atmosphere
    It increases the number of trees
    It reduces the Earth's ability to absorb carbon dioxide

  • Q6
    What effect does deforestation have on the carbon cycle?
    It reduces methane emissions
    It increases carbon dioxide levels in the atmosphere
    It stabilizes carbon levels
    It decreases oxygen production
    30s
  • Q7
    What is one potential impact of deforestation on global temperatures?
    Cooling of the Earth's surface
    Stable temperatures across the globe
    Decreasing sea levels
    Rising global temperatures
    30s
  • Q8
    How can meteorite impacts influence the climate of Earth?
    They only affect the ocean currents.
    They always cause global warming.
    They have no effect on climate.
    They can release large amounts of dust and chemicals into the atmosphere, blocking sunlight and causing temporary cooling.

  • Q9
    How can a meteorite impact potentially influence the atmosphere of Earth?
    It only affects water vapor levels.
    It has no effect on atmospheric gases.
    It removes oxygen from the atmosphere.
    It can release greenhouse gases upon impact, potentially leading to a warming effect.
    30s
  • Q10
    What is a possible short-term climate effect of a significant meteorite impact?
    It creates stronger winds only.
    It has no effect on temperatures.
    It can cause a rapid drop in temperatures due to the blockage of sunlight.
    It results in an immediate increase in plant growth.

  • Q11
    How does albedo affect climate and how does urbanization change albedo levels?
    Urban areas typically have lower albedo than natural landscapes, leading to higher temperatures.
    Urbanization increases albedo by replacing vegetation with concrete.
    Albedo has no effect on climate.
    Higher albedo in cities decreases temperatures.

  • Q12
    What is the relationship between urbanization and local climate?
    Urbanization can create urban heat islands, where temperatures are higher than in surrounding rural areas.
    Urbanization cools down the local climate.
    Urban areas have the same temperature as rural areas.
    Cities do not affect local climate at all.

  • Q13
    Why is albedo important for understanding climate change?
    Albedo has no relevance to climate change.
    Albedo determines the size of clouds in the atmosphere.
    Higher albedo means less solar energy is absorbed, helping to cool the Earth.
    Albedo affects how much solar energy is absorbed or reflected by the Earth, influencing global temperatures.
    30s
  • Q14
    What role does vegetation play in the Earth's albedo and climate?
    Vegetation typically increases albedo by reflecting sunlight and also helps cool the environment through evapotranspiration.
    Vegetation has no impact on local climate.
    All vegetation has the same albedo effect regardless of type.
    Vegetation decreases albedo, absorbing more heat.
    30s
  • Q15
    How can changes in albedo due to urbanization impact global warming?
    Higher albedo helps cool the planet overall.
    Lower albedo in urban areas can contribute to increased global warming by absorbing more heat.
    Urbanization has no effect on global warming.
    Lower albedo reduces the amount of heat absorbed by the Earth.
