Climate Change quix

• Climate change is a long-term alternation of the earth's weather pattern and average temperatures.
• Global Warming results in an increased concentration of greenhouse gases in the atmosphere.
• Greenhouse gases including carbon dioxide(CO2), mathane( CH4), and nitrous oxide (N20).
• Greenhouse effect is trapping the heat and leading to a rise in temperatures worldwide.
• Feedback loop is where the earth warms faster because of the melting snow and ice or from other processes.
• Surface Albedo is where snow and ice reflect sunlight back out to the atmosphere.
• Ocean acidification is caused by the absorption of the excess carbon dioxide that threatens marine ecosystems and biodiversity.
• Carbon neutral is achieving balance between the amount of carbon dioxide emitted and the amount removed from the atmosphere
• Carbon footprint is having an extra greenhouse released bt an individual company or country.
• Mitigation efforts having activities that aim to decrease the emission of greenhouse gases and lessen the severity of climate change.
• Carbon sequestration is the process of capturing and storing carbon dioxide from the atmosphere to mitigate global warming.
• how many ice ages does Earth have?

  5
• What are some effects of a warmer earth?

  melting ice, islands disappearing, floods.
• What is the blanket of the earth?

  Atmosphere
• Eccentricity. How does the earyh's orbit change over a cycle of 100,000 years?

  Circular far away from the sun. Olypticcal closer to the sun.
• how old was the ice in the bottom of their ice core?

  800,000 years
• What is trapped inside of the ice?


  ancient atmosphere and concentration of CO2
• These do not cause global warming

  Pollution, acid rain, ozone hole, nuclear radiation.
• Natural causes- cycles because of the earth's orbit and tilt
• When should the next ice age start?

  30,000 years
• Natural causes- volcanic eruption, asteroid strikes, ocean currents, solar activity, natural resources of greenhouse gases.
• Greenhouse gases- a gas that absorbs heat and acts like a blanket of the earth ( Examples: carbon dioxide CO2, methane CH4, nitrous oxide N20, and water H20)
• Human causes of climate change- release of extra greenhouse gases
• Human Causes of climate change- CO2 from fossil fuels, N20 and CH4 from livestock, farming, landfills, and factories.
• What can the changing tilt or wobble affect?

  changing days and nights
• What do trees normally do to help the situation?

  Capture and accumulate carbon dioxide
• What do fires and farming do?

  release carbon dioxide
• How is the natural greenhouse effect different from the enhanced greenhouse effect?

  more heat escapes into space
• Greenhouse effect- warming of earth's surface and lower atmosphere because of greenhouse gases.
• What is holding the heat in?

  carbon dioxide( CO2), Water (H20), methane (CH4), greenhouse gases
• Sunlight photons- energy particles coming as visible light from the sun, provide light and heat to the earth.
• Infrared photons- particles of heat energy
• Albedo means how well a surface reflects sunlight
• More rocks means more heat
• High albedo- high reflection and low heat
• Low albedo- sunlight absorbed as heat, less energy reflected back into space
• Paleoclimate data- evidence we have of what the climate was like in the past (from tree rings, fossils, rocks, and ice cores).
• species must adapt or go extinct including humans
• Glaciers and sea ice melting, so sea levels are rising
• Changes in weather- heat waves, rainfall amounts, maybe more extreme weather
