Clues

  • A gas that helps to trap “heat” in the atmosphere. Carbon dioxide, methane and water vapour are greenhouse gases. (10, 3)
  • A relationship between two variables, so that if one variable changes, so does the other. This can be positive or negative. (11)
  • A series of enzyme-catalysed reactions carried out in the green parts of plants. Carbon dioxide and water combine to form glucose. This process requires light energy from sunlight. (14)
  • Changes that happen to the global weather patterns as a result of global warming. (7, 6)
  • Layer of gases that surrounds the earth. (10)
  • The increase in the Earth’s average temperature likely to be caused by increased amounts of carbon dioxide in the atmosphere. (6, 7)
  • The release of gases and/or molten rock by volcanoes. (8, 8)
  • The substances and their proportions that make something up. For example, the proportions of today’s atmosphere is 78% nitrogen, 21% oxygen, 1% argon and other gases. (11)
  • When gases in the atmosphere absorb energy transferred by infrared waves from the Earth, which causes the atmosphere to be warmer than it otherwise would be. (10, 6)
  • When one thing can be shown to be causing another thing. (6, 4)
