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 the greenhouse effect,the heat absorbed by the Earth would escape back into space,causing the planet's average surface temperature to drop significantly. Calculations suggest that without this effect,the average temperature of the Earth would be approximately $-18^{\circ}C$,compared to the current average of about $+15^{\circ}C$. Therefore,the Earth would become much colder,making it difficult for life as we know it to survive.

What would happen if the greenhouse effect were not present?
