This pattern is the result of the different amounts of solar heating the place gets depending upon the topography. Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals. This is because cool air holds less water vapor than warm air, so the vapor condenses into either liquid or ice. When a cloud forms at relatively warm temperatures, the particles are usually tiny liquid drops. At very low temperatures, the particles are usually ice.
Clouds can exist in a variety of shapes and sizes.
Clouds are active elements that play a crucial role in determining climatic conditions on our planet. One important area in which clouds play a role is in the energy balance of the Earth, Another important role of clouds in the Earth system involves water transport. Clouds are made of ice or liquid water, and they help redistribute water through the air, returning it to the surface as rain or snow. If the bases of the clouds are between surface to 7,000 feet the clouds are known as Low-level clouds. Low clouds are mostly composed of water droplets.
