the greenhouse effect and our planet (Earth & Space Science)

• Greenhouse Effect


  Gases allow light to shine through the atmosphere then trap the heat, acting like a greenhouse
• Greenhouse Gases


  • Carbon dioxide (CO2)
  • Methane (CH4)
  • Nitrous oxides (NOx)
  • Ozone
  • Fluorinated gases (CFCs, HCFCs)
• Naturally Occurring Sources of Greenhouse Gases

  • Evaporation
  • Respiration
  • Volcanism
  • Decay
  • Swamps
• Man-made Processes Increasing Greenhouse Gases

  • Industrial Revolution
  • Burning fossil fuels
  • Transportation
  • Electricity
  • Deforestation
  • Livestock Farming
  • Landfills
  • Fossil fuel production
  • Agriculture
  • Refrigeration & Cooling
  • Aerosols
• Increase in greenhouse gases due to human activity

  Leads to global warming and climate change
• Climate Change


  • Global warming caused by increase of greenhouse gases
  • Leads to a rise in Earth's average temperature
  • Glaciers and ice caps will melt
  • Sea levels rise and cause flooding
  • Changes in salinity of water
  • Loss of glacier meltwater for drinking, irrigation, and hydroelectric power
• Carbon dioxide is the most common greenhouse gas emitted by human activities, such as burning fossil fuels and deforestation.
• The Earth's atmosphere is made up of gases, including nitrogen, oxygen, carbon dioxide, water vapor, methane, ozone, neon, helium, argon, krypton, hydrogen, xenon, and radon.
• Oxygen makes up about 21% of the air we breathe
• Methane is a potent greenhouse gas with a much stronger warming effect than carbon dioxide, although it stays in the atmosphere for a shorter time.
• Nitrous oxide is another powerful greenhouse gas that is emitted from agricultural and industrial activities.
• Nitrogen makes up about 78% of the air we breathe
• Oxygen makes up about 21% of the air we breathe
• The concentration of carbon dioxide in the atmosphere has increased significantly since the Industrial Revolution, leading to an overall increase in the Earth's temperature.
• Other greenhouse gases include methane, nitrous oxide, ozone, and fluorinated gases like CFCs and HCFCs.
• Sources of greenhouse gases can be natural or man-made, with industrial processes being one of the main contributors.
• Nitrogen makes up about 78% of the air we breathe
• Sources of greenhouse gases can be natural or man-made, with industrial processes being one of the main contributors.
• Methane is another potent greenhouse gas produced through agricultural practices like livestock farming and rice cultivation.
• Greenhouse gases are naturally occurring substances that trap heat from the sun within the earth's atmosphere, contributing to the natural greenhouse effect.
• Human activities have increased the concentration of these gases in the atmosphere, leading to an enhanced greenhouse effect and global warming.
• Nitrous oxide is another powerful greenhouse gas that contributes significantly to global warming.
• Methane is another potent greenhouse gas produced through agricultural practices like livestock farming and rice cultivation.
• Water vapor is also considered a greenhouse gas because it traps heat within the earth's atmosphere.
• Fluorinated gases are synthetic chemicals used in refrigerants, solvents, and foam insulation materials.
• Water vapor is an important component of the Earth's atmosphere, accounting for approximately 70-80% of its mass.
• Carbon dioxide is released into the atmosphere through human activities such as burning fossil fuels, deforestation, and agriculture.
• Human activity has increased the concentration of CO2 in the atmosphere through the use of fossil fuels, deforestation, and other processes.
• Greenhouse gases are important for maintaining life on Earth, but their concentration has increased dramatically over the past century due to human activities like burning fossil fuels and deforestation.
• Water vapor is naturally present in the atmosphere but can also be produced by evaporation or condensation processes.
• Human activity is responsible for most of the recent increase in atmospheric CO2 levels.
• Human activity such as burning fossil fuels, deforestation, and agriculture contribute to the release of these gases into the environment.
• Agriculture


  • crops
  • clothing
  • trade
• Reducing Greenhouse Gases


  • I drive less
  • fly less
  • reduse, reuse, recycle
  • plant trees
  • use less electricity
  • eat less meat
• Changes in precipitation
