Particulate Matter
Tiny solid and liquid particles suspended in the atmosphere are called aerosols. These particles can come from various sources such as industrial activities, dust, volcanic eruptions, and wildfires, and can affect air quality and climate.
Liquid droplets can enter the atmosphere through processes like evaporation, condensation, and aerosolization. For example, water droplets can evaporate from bodies of water and enter the atmosphere as water vapor, which can then condense to form clouds. In addition, liquid droplets can be aerosolized through activities such as combustion or volcanic eruptions, leading to their suspension in the atmosphere.
Clouds are primarily composed of water droplets or ice crystals formed from water vapor in the atmosphere. While hydrogen is present in trace amounts in Earth's atmosphere, it is not a major component of clouds.
When water vapor molecules in the atmosphere stick to particles in the air and become a liquid, it is called condensation. This process occurs when the air cools down, causing the water vapor to lose energy and turn into liquid droplets.
Gaseous
Water droplets and clouds form through a process called condensation, where water vapor in the air changes into liquid droplets as it cools. This can happen when warm air rises, cools, and reaches its dew point, causing the vapor to condense onto tiny particles like dust or salt in the atmosphere. As more droplets gather, they form clouds.
Liquid droplets in air are called mists, smaller droplets are aerosols. Solid particulates are dust, smaller sized ar fumes.
Clouds are composed of water droplets or ice crystals that have condensed around tiny particles in the atmosphere, such as dust, pollutants, or salt. They also contain air and varying levels of moisture.
condenses
Rain exists in the liquid phase, as it is water droplets that have condensed and fallen from the atmosphere.
The suspended liquids in the atmosphere are called aerosols. Aerosols can include liquid droplets, solid particles, or a combination of both, and they play a role in various atmospheric processes such as cloud formation and air pollution.
Clouds are composed of water droplets or ice crystals that have condensed from water vapor in the atmosphere. While they are formed from gases, clouds are considered visible collections of water in liquid or solid form, rather than a gas.
