Answer :
Final answer:
Mold and moss commonly grow on the exterior of a home due to excessive moisture and shade, with high humidity also being a contributing factor, especially in poorly ventilated areas. Such growth can lead to health problems due to allergens and irritants.
Explanation:
The common cause of mold and moss growth on the exterior of a home is excessive moisture and shade. These conditions are ideal for moss and mold because they thrive in damp and poorly lit environments. An environment with high humidity can also foster the growth of these organisms, especially in areas of a home that lack proper ventilation. Just as molds are known to grow in indoor settings like showers and basements, they can similarly affect the outside of a home in damp and shaded areas. Notably, if mold spores land on a wet or damp spot, they can start growing, becoming potential contributors to health problems due to the allergens and irritants they produce.
