RAIN ASHLEY = PINK MEKAI = GREEN Rain is moisture condensed from the atmosphere that falls from the sky in droplets. Rain is made when warm moist air cools and the vapor changes to liquid. Warm air can hold more water than cool air. When the warmer air is cooled the moisture changes to liquid. Then it rains. During the water cycle, water vapor cools and condenses. Then clouds are formed. Clouds are made of billions of tiny water droplets and ice crystals floating in the sky. The ice crystals come in many different shapes and sizes depending on how and where they formed. The rain is then formed when the water droplets are too heavy to stay in the air. Rain is formed by warm air that rises up into the sky. When warm air gathers together clouds are formed. When the droplets get bigger and heavier, they form rain. On hot days, the suns heat evaporates the water from ocean. The condensed air goes up into the sky and starts to form clouds. When the cloud gets heavy with evaporated water it rains. Rain can be measured by using a rain gauge. There are many different types of rain gauges. They vary in shapes and sizes from a straight sided cylinder to a funnel shape. All rain gauges have a calibrated measuring device. If the rain gauge is a cylinder, measure the amount of water in the cylinder with a ruler. That would tell you the amount of rainfall if there was no evaporation. Most rain gauges are funnel shaped. Funnel shaped rain gauges are designed to be more accurate. The rain is collected in a funnel device that has a specified size larger than the collector. The collector has the measuring markers to match the unit of measure.
