All other options are wrong, as in this countries also these ideals spread from Ancient Greece.
The average temperature of Earth given the solar irradiance is 238.4K.
<h3>How to calculate the temperature?</h3>
The following can be deduced from the information:
Let Earth's albedo =α =0.33
Radius of sun ( Rs) =6.955×10⁵
Value of Boltzmann constant= 5.67×10-⁸
L= 1350
T = average temperature
L= 4σ (Te)⁴ / (1-α)
1 - 0.33 = 4 × 5.67×10-⁸×(T)⁴ / 1350
0.67 × 1350 = 0.0000002268*(T)⁴
(T)⁴ = 3230357142.9
T = 238.4 k
In conclusion, the temperature is 238.4K.
<u>Complete question:</u>
Calculate the average temperature of Earth where the solar irradiance (L) is 1350W/m² and the albedo of Earth is 0.33. Consider Earth to be a perfect black body and the Stefan - Bollzmann constant to be 5.67 × 10^-8 W.

Answer:
Explanation:
Importance of troposphere to life on earth
The study of the troposphere is very important because we breathe the air in this layer of air. ... Tropospheric processes, such as the water or hydrologic cycle (the formation of clouds and rain) and the greenhouse effect, have a great influence on meteorology and the climate.
