Other important processes that form precipitation are riming, when a supercooled liquid drop collides with a solid snowflake, and aggregation, when two solid snowflakes collide and combine. The precise mechanics of how a cloud forms and grows is not completely understood, but scientists have developed theories explaining the structure of clouds by studying the microphysics of individual droplets.
Forces. of attraction between the particles hold them together and keep them in place. The particles in solids are arranged in a regular way. The particles in solids move only by vibrating about a ...
Jun 15, 2023 · When a droplet starts sliding on a solid surface, the friction between the droplet and the solid surface behaves in a manner comparable to solid–solid friction [1]: a threshold of static friction force must be overcome to initiate the slide of the droplet, and after that, a lower kinetic force can maintain the droplet movement (Fig. 1a).
1. The sun – The sun heats the ground, which then heats the air just above it, causing it to rise upwards in the sky (warm air rises). This tends to produce cumulus clouds. 2. Hills and mountains - When air is travelling towards a mountain or hill, it cannot go into the hill and so it rises upwards along the terrain.
Mar 28, 2023 · As a result, cloud droplets are constantly forming and dissipating. When more water condenses on nuclei than evaporates from them, clouds form and grow. Conversely, if there is more evaporation than condensation, clouds dissipate. This is why clouds appear and disappear as well as constantly change shape. Learning Lesson: Smoking Clouds.
Sep 25, 2024 · The Short Answer: Clouds are created when water vapor, an invisible gas, turns into liquid water droplets. These water droplets form on tiny particles, like dust, that are floating in the air. A camera on NASA’s Terra satellite captured this image of clouds over the Southern Indian Ocean.

Feb 4, 2019 · Step 1: Change Water Vapor into Liquid Water. Although we can't see it, the first ingredient -- water -- is always present in the atmosphere as water vapor (a gas). But in order to grow a cloud, we need to get the water vapor from a gas to its liquid form. Clouds begin to form when a parcel of air rises from the surface up into the atmosphere.
