Which one of the following pairs is mismatched?

Options

  1. ABiomass burning - Release of CO ₂
  2. BFossil fuel burning - Release of CO ₂
  3. CNuclear power — Radioactive wastes
  4. DSolar energy — Green house effect

Correct answer

D. Solar energy — Green house effect

Step-by-step solution

Solar energy is not responsible for green house effect instead it is a source of energy for the plants and animals. Green plants prepare their food by the use of this solar energy. CO ₂ gas is mainly responsible for green house effect. Excess of this gas forms a thick layer around the earth and prevents re-radiation of entering sun rays to atmosphere. Thus functions like the glass panels of a green house (or the glass windows of a motor car). This is so called green house effect.
