• What are the two terms often associated with environmental issues discussed in the video?

  Global warming and climate change
• What is the primary difference between global warming and climate change?

  Global warming refers to temperature increase
• What role does the atmosphere play for life on Earth?

  It acts as an insulating blanket
• How does the temperature of the moon compare to Earth?

  The moon has extreme temperature variations
• What happens to the sun's heat energy when it reaches the Earth's surface?

  Some is absorbed, most is re-emitted
• What is the process by which heat energy stays close to Earth?

  Absorption and re-emission by gas particles
• What are greenhouse gases responsible for?

  Global warming
• How has the strength of the greenhouse effect changed over Earth's history?

  It has grown and shrunk repeatedly
• What gases are primarily responsible for the current increase in the greenhouse effect?

  Carbon dioxide and methane
• What is the current trend in Earth's temperature over the past century?

  It has increased by almost one degree
• What does the term climate refer to?

  Long-term weather patterns
• What are some consequences of global warming on weather events?

  More common and severe rare weather events
• What are the two reasons for sea level rise due to global warming?

  Melting ice and expanding ocean water
• How does melting ice contribute to sea level rise?

  It flows into the ocean, increasing volume
• What are some adaptations species might make due to climate change?

  Adaptation or migration to better regions
• What is likely to happen to biodiversity in the coming decades?

  Biodiversity is likely to fall dramatically
• What should viewers do if they enjoyed the video?

• What impact does climate change have on wild organisms?

  Species may not survive changing conditions
• What is the role of the atmosphere in temperature regulation?

  It maintains a stable temperature
• What happens to energy that is re-emitted by gas particles in the atmosphere?

  It is sent in random directions
• How does the accumulation of greenhouse gases affect global temperatures?

  It causes an increase in global temperatures
• What is considered the most important limited resource for humans?

  Land
• Why do humans use land?

  For building, farming, and resource extraction
• What is the consequence of using more land for human activities?

  Less land is available for other organisms
• What are the knock-on effects of converting land?

  It damages the environment further
• What are the main uses of land by humans?

  • Building towns and cities
  • Quarrying for resources
  • Farming
  • Dumping waste
• What is the term for cutting down forests?

  Deforestation
• What is the primary reason for deforestation?

  To clear land for farming
• What is one use of crops grown from deforested land?

  To raise cattle
• What are biofuels?

  Plant-based fuels
• What is logging?

  Clearing forests for wood
• Where is deforestation currently happening a lot?

  Tropical regions
• What are the three main problems caused by deforestation?

  1. Increased carbon dioxide in the atmosphere
  2. Release of carbon from burning trees
  3. Loss of biodiversity and habitats
• How does deforestation contribute to global warming?

  By increasing carbon dioxide levels
• What happens when forests are burned during clearing?

  They release stored carbon as carbon dioxide
• What is the effect of habitat destruction on biodiversity?

  It reduces biodiversity
• What are peat bogs?

  Acidic and waterlogged areas of land
• Why can't microorganisms decay plants in peat bogs?

  Too acidic and waterlogged conditions
• What substance is formed in peat bogs?

  Peat
• How does peat help with global warming?

  It stores carbon instead of releasing it
