Sep 29, 2025 · 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.

Jul 1, 2025 · When more water condenses on nuclei than evaporates from them, clouds form and grow. Conversely, if there is more evaporation than condensation, clouds dissipate.

Eventually, enough moisture will condense out of the air to form a cloud. Several types of clouds form in this way including cumulus, cumulonimbus, mammatus, and stratocumulus clouds.

Clouds form because moist air rises, expands, and cools to the dew point, causing water vapor to condense onto microscopic particles in the atmosphere.

Clouds appear when there is too much water vapour for the air to hold. The water vapour (gas) then condenses to form tiny water droplets (liquid), and it is the water that makes the cloud …

Apr 29, 2025 · Clouds begin to form when moist air rises and cools, causing water vapor to condense. Cloud droplets need tiny particles in the air called condensation nuclei to form. New …

Jul 11, 2023 · The shape of a cloud is determined by air temperature, density and movement. Differences in temperature and density prevent water-laden air from mixing with the …

Jun 10, 2025 · To understand how clouds get their shape, it helps to understand the basics of how they form. When air rises and cools, the water vapor it holds condenses into tiny water …

When the sun warms the planet and heats oceans, rivers, lakes, and other water bodies at ground level, water vapor rises away from the surface of the Earth. As it moves up, it gets colder, and …

Sep 12, 2025 · Clouds are formed when relatively moist air rises. As a mass of air ascends, the lower pressures prevailing at higher levels allow it to expand.
