A Critically Important Part of the Hydrologic Cycle Is the Transpiration

question 151

Essay

A critically important part of the hydrologic cycle is the transpiration of water through plants into the atmosphere. This water has traveled from the roots up to the top leaves and then moves out as water vapor. In the case of some plants, such as redwood trees, this can be a distance of hundreds of feet. Explain how it is that water can move up naturally, when forces of gravity might make one think that this is impossible.
