The increasing amount of carbon dioxide in the air is slowly raising the temperature of the atmosphere, because it absorbs
✓ Correct answer: d) The infrared part of the solar radiation.
ExplanationGreenhouse Effect is a naturally occurring phenomenon that warms and covers the lower atmosphere of the planet, keep- ing it at a temperature where life may survive.The earth’s cooling and warming are balanced by them.Without this, the current 15 degrees Celsius average temperature of the earth’s surface would be -19 degrees Celsius.Human-induced greenhouse gas emissions upset the natural balance & lead to increased warmth.Option (d) is correct: Carbon dioxide absorbs the infrared (IR) radiation emitted by the Earth’s surface.When sunlight reaches the Earth it warms the surface, which then re-emits this energy as infrared radiation.CO₂ molecules absorb this IR radi- ation, trapping heat in the atmosphere and causing the tempera- ture to rise.The increasing amount of carbon dioxide in the air is slowly raising the temperature of the atmosphere because it ab- sorbs the infrared part of the solar radiation.It absorbs energy with a wavelength of 15 μm (micrometres).111
