Which of the following increases atmospheric loss by thermal escape? a. increasing the mass of the gas particles b. increasing the temperature of the atmosphere c. increasing the escape velocity of the planet d. all of the above

B. increasing the temperature of the atmosphere

Explanation:

Generally, atmospheric loss can be defined as the loss of the gases in the atmosphere to outer space. This process usually occur through either thermal escape or non-thermal escape. Atmospheric loss of gases to outer space by thermal escape occurs when the molecular velocity due to thermal energy is considerably high. One of the factors that can lead to increase in thermal energy and ultimately increase in atmospheric loss is increase in the temperature of the atmosphere. Therefore, the correct answer is option B.
