From where does the heat come in the environment?

A. Insolation

B. Radiation

C. Condensation

D. Convection

Answer: Option A

Solution(By Examveda Team)

Earth receives its heat from sun in the form of Insolation (short wavelength) and radiates it back in the form of long wavelength waves. Our atmosphere is transparent to short wave radiations but traps long wave radiations that is why it is heated from below.
