Question

Without Greenhouse effect the average temperature of earth surface would have been

• A. ${18}^{\circ }\text{C}$
• B. ${18}^{\circ }\text{C}$
• C. ${18}^{\circ }\text{C}$
• D. $-8^{\circ }\text{C}$

Answer 1

The correct option is C ${18}^{\circ }\text{C}$

The greenhouse effect is a naturally occuring phenomenon that is responsible for heating of Earth’s surface and atmosphere. Without a greenhouse effect, the average temperature at earth’s surface would have been around $-{18}^{\circ }\text{C}$, rather than the present average of $+{15}^{\circ }\text{C}$.
