Water vapor needs a surface to condense onto. Dust particles, salt particles from the ocean, or other microscopic particles known as condensation nuclei provide the surface for water vapor to condense and form cloud droplets. When the water vapor condenses onto condensation nuclei, it forms cloud droplets. These droplets continue to accumulate and collide with each other, forming visible clouds. The type of cloud that forms depend on various factors such as temperature, humidity, and atmospheric pressure. Common types of clouds include cumulus clouds or the puffy and cotton-like clouds, stratus clouds or the layered clouds, cirrus clouds or the thin and wispy clouds and cumulonimbus clouds or the towering and thunderstorm clouds.

Answer (1)
A 1) cloud is a visible condensation of water that is suspended in the air. Clouds form as 2) water vapor in the atmosphere rises and then cools. The 3) air heats water, which causes it to 4) evaporate into the air. Warmer air rises and cooler air sinks. As the warmer air containing water vapor rises, it is cooled. As the water vapor cools, it 5) condenses into water droplets onto particles, such as dust, in the air. As more and more air cools, more droplets form and create different visible 6) clouds.
