Question

The temperature of the earth without the greenhouse effect will be: Options:

• A. \( 0^\circ C \)
• B. \( -18^\circ C \)
• C. \( -10^\circ C \)
• D. \( -24^\circ C \)

Hint:

The greenhouse effect increases the Earth's surface temperature by trapping infrared radiation emitted by the Earth's surface. Without this effect, the Earth's temperature would be much colder.

Answer 1

The Correct Option is B

The current average temperature of the Earth is around \( 15^\circ C \). The greenhouse effect raises the Earth's temperature by trapping infrared radiation. Without the greenhouse effect, the temperature of the Earth would be significantly lower, approximately \( -18^\circ C \). This is because the Earth would lose more heat to space without the atmosphere's insulating properties.
Conclusion: The temperature of the Earth without the greenhouse effect is approximately \( -18^\circ C \). Final Answer: \[ \boxed{-18^\circ C} \]
