global warming

• What are the two terms discussed in the video?

  Global warming and climate change
• What is the atmosphere's role for Earth?

  It acts as a protective layer of gases
• How does the atmosphere regulate Earth's temperature?

  It acts like an insulating blanket or greenhouse
• How does the temperature on the Moon compare to Earth?

  It varies from +100 to -200 degrees
• What happens to the sun's heat energy when it reaches Earth?

  Some is absorbed, most is re-emitted or reflected
• What occurs to energy absorbed by gas particles in the atmosphere?

  It is re-emitted in random directions
• What is the greenhouse effect?

  It keeps heat energy close to Earth
• What gases are considered greenhouse gases?

  Carbon dioxide, methane, and water vapor
• How has the strength of the greenhouse effect changed over time?

  It has grown and shrunk repeatedly
• What is the main cause of current global warming?

  Human activities releasing carbon dioxide and methane
• How much has the Earth warmed in the past 100 years?

  Almost one degree Celsius
• What does climate change refer to?

  Effects of global warming on climate
• What are some consequences of global warming?

  More common and severe weather events
• What causes sea level rise due to global warming?

  Melting ice and expanding ocean water
• What will happen due to rising sea levels?

  Seasonal flooding and submersion of land
• How does climate change affect wild organisms?

  Species may not survive changing conditions
• 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?

  It is likely to fall dramatically
• What are the main differences between global warming and climate change?

  • Global warming refers to the increase in Earth's average temperature.
  • Climate change encompasses the broader effects of global warming on weather patterns.
• What processes contribute to the greenhouse effect?

  1. Absorption of heat by greenhouse gases.
  2. Re-emission of heat in random directions.
  3. Repeated collisions with gas particles.
• What are the potential impacts of climate change on weather events?

  • Increased frequency of droughts.
  • More severe hurricanes and floods.
  • Changes in long-term weather patterns.
• What are the two main reasons for sea level rise?

  1. Melting ice from higher temperatures.
  2. Expansion of warming ocean water.
• How might species respond to changing climates?

  • Some may adapt to new conditions.
  • Others may migrate to cooler areas.
  • Many may face extinction due to rapid changes.
