  "definition": "1. Evaporation of water from soil, and transpiration of water from plants.\n\n2. Plants absorb water through their roots and emit it through their leaves. This movement of water is called \"transpiration.\" Evaporation, the conversion of water from a liquid to a gas, also occurs from the soil around vegetation and from trees and vegetation as they intercept rainfall on leaves and other surfaces. Together, these processes are referred to as evapotranspiration, which lowers temperatures by using heat from the air to evaporate water.\n\n3. The loss of water from the soil both by evaporation and by transpiration from the plants growing in the soil.\n\n4. The release of water vapor into the atmosphere by the combination of direct evaporation and transpiration by plants.\n\n5. (ee-VAP-o-TRANS-purr-A-shun) The combined processes of evaporation and transpiration. It can be defined as the sum of water used by vegetation and water lost by evaporation.\n\n6. The combined process of evaporation from the Earth's surface and transpiration from vegetation.\n\n7. The loss of water from the soil by evaporation and by transpiration from the plants growing in the soil, which rises with air temperature.\n\n8. Water losses from the surface of soils and plants.\n\n9. The sum of evaporation and plant transpiration from the Earth's land and ocean surface to the atmosphere. Evaporation accounts for the movement of water to the air from sources such as the soil, canopy interception, and water bodies. Transpiration accounts for the movement of water within a plant and the subsequent loss of water as vapor through stomata in its leaves.\n\n10. The sum of evaporation and transpiration.\n\n11. The loss of water from the soil both by evaporation and by transpiration from the plants growing in the soil. [Chesapeake Bay Glossary]\n\n12. Sum of evaporation and plant transpiration from the Earth's land and ocean surface to the atmosphere. Evaporation accounts for the movement of water to the air from sources such as the soil, canopy interception, and water bodies. Transpiration accounts for the movement of water within a plant and the subsequent loss of water as vapor through stomata in its leaves.\n\n13. Sum of evaporation and plant transpiration. Potential evapotranspiration is the amount of water that could be evaporated or transpired at a given temperature and humidity. if there was plenty of water available. Actual evapotranspiration can not be any greater than precipitation. and will usually be less because some water will run off in rivers and flow to the oceans. If potential evapotranspiration is greater than actual precipitation. then soils are extremely dry during at least a major part of the year.",
