Q136 / 160 · AP EAMCET 2023 (19 May Shift 1) · Physics

The temperature of the earth without green house effect will be

A
$0^{\circ} \mathrm{C}$
Correct answer
B
$-18^{\circ} \mathrm{C}$
C
$-10^{\circ} \mathrm{C}$
D
$-24^{\circ} \mathrm{C}$

Solution

Without natuarally occurring greenhouse gases; Earth's average temperature would be near $-18^{\circ} \mathrm{C}$.

Hence, the correct answer is option: 'B'.
