Question

Explain the physical change that causes clouds to form?

Answer 1

A cloud is a visible mass of minute liquid droplets, ice crystals, or other particles floating in the atmosphere of a planetary body or comparable space, according to meteorology. The droplets and crystals might be made of water or a variety of different substances. On Earth, clouds develop when the air is chilled to its dew point, or when it receives enough moisture (typically in the form of water vapour) from a neighbouring source to raise the dew point to the ambient temperature.

Complete answer:
Condensation is the physical transformation of water from vapour to liquid in cloud formation. Cloud formation is a physical change that occurs when water evaporates in the process of evaporation and then condenses in the air to create clouds. Precipitation returns this water to the ground. This procedure is performed over and over. As a result, cloud formation is a physical change.
Clouds are clumps of solidified liquid droplets, solid particles, or crystalline particles suspended or floating in the air that have a light colouring. These are found in the troposphere, stratosphere, and mesosphere, which make up the earth's homosphere. Based on the density of the atmosphere and climatic circumstances, they emerge in a variety of forms, including sheet or ripple form. Clouds arise when water droplets in vapour form are absorbed into the air by evaporation, mostly from water bodies such as oceans and rivers, and then travel in a condensed form through the air. When the amount of air in the atmosphere grows, the atmosphere rises with it. It cools off after a time.
The ability of the air to contain all of the water vapour inside itself decreases as the temperature drops. It then transforms into microscopic water droplets or ice crystals, forming a cloud.
When it comes to the place where clouds originate and their shape, there are two sorts of clouds. There are two types of clouds: high clouds and low clouds. On the top portion of the sky, high clouds develop. Low clouds originate at the bottom of the sky, usually within a kilometre or two of the Earth's surface. They're also known as fog. Between low and high clouds, middle-level clouds develop.

Note:
Tropospheric clouds have the potential to influence global climate change. They may deflect incoming solar rays, resulting in a cooling impact where and when these clouds form, or they may trap longer wave radiation that reflects back up from the Earth's surface, resulting in a warming effect. The major variables that impact the local heating or cooling of Earth and the atmosphere are the height, shape, and thickness of clouds. Clouds that develop above the troposphere are too few and too thin to have any impact on global warming. The major source of uncertainty in climate sensitivity is clouds.
