Final answer:
During a thermal inversion, the temperature increases with altitude due to the inversion of the thermal lapse rate.
Step-by-step explanation:
According to the question, during a thermal inversion, the temperature increases with altitude. This is because of the inversion of the thermal lapse rate. Normally, air temperature decreases with an increase in altitude, but during an inversion, warmer air is held above cooler air, causing the temperature profile to be inverted.
