Question

Quizplus · Accepted Answer

Aerosols are very small liquid or solid particles that are suspended in the atmosphere. They can come from natural sources (e.g. dust, sea salt, pollen) or human activities (e.g. combustion, industrial processes). Aerosols are important because they play a role in the Earth's climate by scattering and absorbing sunlight, which can affect the amount of solar radiation that reaches the Earth's surface and change the balance of energy in the atmosphere. They also impact air quality and human health, as some aerosols can be harmful when inhaled.
