Describe two ways that water moves through the earths biosphere in the water cycle

Answers

For the first one I would say that the water cycle would be affected because there would be more water in the ground. The roots of the trees soak up the water and keep excellent drainage under the ground. Without trees this mechanism would be all sorts of messed up.
