What is the property of water that allows raindrops to form?
Raindrops are held together by surface tension. This is the ability of water to form an outer skin that holds it together. It is caused by weak hydrogen bonds.
Precipitation. Continued cooling of the water vapor in the clouds causes water droplets to grow. Eventually, droplets join other droplets and form drops too heavy to stay in the clouds. The heavy droplets begin to fall as rain. The movement of raindrops from the atmosphere to the Earth is precipitation. Snow may form instead of raindrops if the water vapor condenses below the freezing point. Some areas lose more water to evaporation than they gain…
Water vapor and clouds are the stages of the water cycle. The sun (without it water cycle count repeat.) shines on the water causing gas to form above the ground and in the air. This is called water vapor. Water vapor accumulates and forms clouds. Once dense enough from all the water vapor it will then precipate as raindrops.
