THE WATER CYCLE INSIDE A TERRARIUM
ОглавлениеThe water cycle inside a terrarium is not much different than the one outside. The three stages are transpiration, evaporation, and condensation. In a terrarium, the glass vessel takes the place of our atmosphere by holding the soil, water, and all living things inside. First, water is transported from the roots through the plant’s leaves and released into the air through their leaves in a process called “transpiration.” As the sun heats up the vessel, water is evaporated into the air. If you look closely you may even see a light mist or fog inside. As the air inside the terrarium becomes humid, or saturated with water vapor, it starts to condense and create liquid water on the glass. Eventually the water slides down and back into the soil. The water is recycled over and over so there is no need to continuously water a closed terrarium.
