Process by which water that is absorbed by plants, usually through the roots, is evaporated into the atmosphere from the plant surface, such as leaf pores. Transpiration
Water that falls and penetrates into the ground. Factors affecting infiltration; amount of precipitation, soil characteristics, soil saturation, land cover, slope of the land, and evapotranspiration. Infiltration

Third layer of the atmosphere where air temperature decreases with altitude and very little solar radiation is absorbed. Mesosphere
Fourth layer of the atmosphere that has a very low density and absorbs a large amount of the Sun’s radiation so its temperature increases with height. Thermosphere
