Vedclass · Answer

(B) The greenhouse effect is a natural process that warms the Earth's surface.When the Sun's energy reaches the Earth's atmosphere,some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.Without these naturally occurring greenhouse gases,the Earth's average surface temperature would be approximately $-18^{\circ} C$,which is significantly colder than the current average of about $+15^{\circ} C$.

The temperature of the Earth without the greenhouse effect would be: (in $^{\circ} C$)
