Question

thermal inversion occurs when a layer of warm air forms over a layer of cool air. which of the following are characteristics of thermal inversion? choose 2 answers: a the morning ground is covered in frost. b particles are suspended in dense fog. c in low areas and valleys, inversions are less likely. d the abundance of oxygen in the air decreases.

Explanation:

Thermal inversion traps cooler air near the surface. Frost can form on the ground in the morning due to the cold air being trapped. Also, particles can be suspended in dense fog as the inversion layer prevents normal air - mixing and dispersion. Inversions are more likely in low areas and valleys, and thermal inversion doesn't directly cause a decrease in oxygen abundance.

Answer:

A. The morning ground is covered in frost.
B. Particles are suspended in dense fog.
