Greenhouse Effect
1 Definition
  • The greenhouse effect is a natural process in which some gases in the atmosphere trap heat from the Sun.
  • This trapped heat keeps Earth warm enough for life.
  • Main greenhouse gases include carbon dioxide (CO₂), methane, and water vapor.
2 Uses
  • The natural greenhouse effect helps maintain a suitable temperature for plants, animals, and humans.
  • Without it, Earth would be too cold and much water would stay frozen.
  • It supports farming and ecosystems by keeping climate conditions stable.
3 Effects
  • When greenhouse gases increase too much, extra heat gets trapped.
  • This causes global warming and changes in weather patterns.
  • Examples include heat waves, irregular rainfall, and stronger storms.
4 Impact
  • Melting glaciers and rising sea levels can affect coastal areas.
  • Crop production may decrease in some places due to droughts or floods.
  • People, animals, and plants can face health and habitat risks.
