Transpiration is the process by which plants lose water in the form of vapor through their stomata (small openings on the leaves). It is a part of the water cycle and plays a significant role in the circulation of water in the environment. Transpiration helps plants absorb nutrients from the soil, cools the plants, and maintains their structure. It also contributes to the moisture in the atmosphere and provides moisture for cloud formation and precipitation.
Where does the energy come from to power the water cycle?
The energy that powers the water cycle primarily comes from the sun. Solar energy heats the Earth's surface, causing water to evaporate from oceans, lakes, and rivers, and to transpire from plants. This process is known as evapotranspiration. The heat energy from the sun also causes the atmosphere to warm up, enabling the warm air to hold water vapor (humidity). As the warm, moist air rises, it cools down, causing the water vapor to condense and form clouds. The energy from the sun is also responsible for driving other elements of the water cycle, such as precipitation and runoff. Overall, solar energy is the primary source of energy that powers the water cycle.
