What is the role of sunlight in the formation of photochemical smog?

• It cools down the pollutants, reducing smog formation

• It acts as a catalyst in the chemical reactions that produce smog

• It has no significant role in smog formation

• It dissolves the pollutants in the atmosphere

• Paint

• Cleaning supplies

• Pine and floral scents

• M&M's

What is the primary difference in the origin of "good" ozone compared to "bad" ozone?

What health effects can be caused by PANS (Peroxyacetyl nitrates)?

• Irritates eyes, nose, and throat

• Improves respiratory function

• Reduces risk of heart disease

• burnt scrambled eggs

Which of the following is a method to reduce photochemical smog?

What weather condition is necessary for a thermal inversion to occur?

• Windy conditions to mix the air

• Windless to prevent mixing of air

• Heavy rainfall

• High humidity

What natural features act as barriers to deter vertical mixing of air, contributing to the formation of thermal inversions?

• Rivers & plains

• Valleys & nearby mountain ranges

• Forests & wetlands

• Deserts & plateaus

Why are thermal inversions dangerous in large cities, high traffic areas, and industrialized regions?

• They allow for better dispersion of pollutants.

• They cause a decrease in air temperature.

• They trap pollution below the warm layer and prevent it from dissipating.

• They increase the humidity levels in the air.
