Question

Explain global warming and effect of greenhouse gases.

Answer 1

Global warming is the unnatural rise in the temperature of the earth’s surface due to increased amounts of green house gases in the earth’s atmosphere. Green house gases such as carbon dioxide, methane and water vapour trap the solar radiation and keep our planet warm without which Earth would have been too cold to support life. Green house effect becomes a cause of concern only when there is an increase in the amounts of these gases which leads to a rise in the earth’s surface temperature beyond normal levels. This can lead to the destruction of habitats and disturb life on earth.
