Earth Science

Earth science is the study of the Earth's structure, properties, processes, and four and a half billion years of biotic evolution.  Understanding these phenomena is essential to maintenance of life on the planet.  The expanding world population demands more resources; faces increasing losses from natural hazards; and releases more pollutants to the air, water, and land.   Sustaining our existence requires scientific understanding of the natural materials and processes linking the geosphere, hydrosphere, atmosphere, and biosphere.  Life prospers or fails at the surface of the Earth where these environments intersect.
