Final answer:
Yes, atmospheric conditions can affect the size of the chemically hazardous area.
Step-by-step explanation:
Yes, atmospheric conditions can affect the size of the chemically hazardous area. Changes in atmospheric composition, such as an increase in greenhouse gases like carbon dioxide, can lead to changes in temperature and weather patterns. These changes can impact the dispersion and concentration of hazardous chemicals in the atmosphere, potentially increasing the size of the hazardous area.
