This short video (~2 minutes) explains how a raindrop falls through the atmosphere and why a more accurate look at raindrops can improve estimates of global precipitation. This information is important to scientists working on the Global Precipitation Measurement (GPM) mission - understanding the micro world of raindrops provides insight to scientists about the macro world of storms.
Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.
By the end of this section, you will be able to:Define water potential and explain how it is influenced by solutes, pressure, gravity, and the matric potentialDescribe how water potential, evapotranspiration, and stomatal regulation influence how water is transported in plantsExplain how photosynthates are transported in plants
View the five processes of the hydrologic cycle in this interactive resource adapted from NASA in which animations illustrate condensation, precipitation, infiltration, runoff, and evapotranspiration.
