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.

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

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 when the invisible water vapor in the air condenses into visible water droplets or ice crystals. For this to happen, the parcel of air must be saturated, i.e. unable to hold all the water …

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 …

Feb 13, 2023 · Clouds form when moist air in the atmosphere rises through evaporation due to heating the Earth’s surface. The water vapor eventually condenses into water droplets as the …

Jul 11, 2023 · Moisture is always present in the air as water vapour, but when it condenses into liquid droplets or solid ice particles, these particles scatter light, making them visible as clouds. …

Aug 8, 2025 · When the Sun heats the Earth, water evaporates to form water vapor. The warm, moist air then rises into the atmosphere (hot air being lighter rises). As the saturated air …
