Explanation: When the sun heats up the air in the atmosphere, the air becomes less dense, hot and rises upward. As the hot air rises, the heavier (more dense) cool air moves downwards and fills the atmosphere. This creates circulation patterns known as convection currents in the atmosphere.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
