Green House Effect Explained

Green House Effect is defined as , “the trapping of the sun’s warmth in a planet’s lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet’s surface.”

Green House Gases

It is caused by gases in the atmosphere that trap energy from the sun. These heat-trapping gases are called greenhouse gases. The most common greenhouse gases are water vapor, carbon dioxide, and methane. Without the greenhouse effect, Earth would be too cold for life to exist.

Global Warming

Land, oceans, and plants absorb, or soak up, energy from sunlight. They release some of this energy as heat. Greenhouse gases absorb the heat and then send it back toward Earth. Without greenhouse gases, this heat would escape back into space. However with the increased amount of these gases in the atmosphere, the global temperature of the Earth is rising causing Global Warming.

Scientists believe that human activities are increasing the greenhouse effect. When people drive a car or operate a factory they burn coal, oil, and other fossil fuels. This adds extra greenhouse gases to the air, and the extra gases trap more heat. Many scientists think that this has led to Global Warming, or a steady rise in the average temperature of Earth’s surface.

  1. Pooja, thank you for the link.

    The question was posted in the context of the most abundant and harmful greenhouse gas not just the quantity in the atmosphere. So that has been rectified.

    We look forward to hearing from you more on the other quizes as well.

  2. The greenhouse gases in the atmosphere act in much the same way as the glass panels of a greenhouse, which allow sunlight through and trap heat inside. Hence the name.
