Water Vapor and Weather
Caption: This hygrometer is used to measure humidity.
Water on Earth can be found in three forms or states. Water in a solid state is ice. We know water best as a liquid. It can also be a gas called water vapor.
Water vapor is water in the form of an invisible gas. It is held in the air until it changes back to water. When the air gets cooler, the water can condense in the air. It changes from a gas into a liquid. It first condenses as tiny little droplets, which make clouds. When the droplets get bigger and heavier, they are pulled to the ground by gravity. This is precipitation. Precipitation can be rain. It can be frozen precipitation called sleet, snow, or hail. It can be drops of dew on the grass in the morning. It can be frozen dew that we call frost.
