Over land, about 90% of the water that reaches the atmosphere evaporates from the surfaces of plants through a process called transpiration.

Permeability vs porosity

Permeability is a measure of how quickly water infiltrates soil (highest in soil with large pores, such as sand, and lowest in soils with small pores, such as clay). Porosity is a measure of the total pore space in soil. (Porosity is actually highest in fine-textured soils such as clays. Although the pores in such soils are small, the total air space is higher. By comparison, the porosity of sand is low. Therefore, although it seems contrary to what you might expect, permeability increases as porosity decreases, and vice versa.)
