ESS2.C: The Roles of Water in Earth’s Surface Processes

 

In this video Paul Andersen explains the vital role that water plays in the processes on the Earth's surface.  Water has several unique properties including high heat capacity, transparency, polarity and the ability to change the chemical behavior of the mantle.  The Earth is largely a water planet but most of the water is found in the oceans or locked in ice.  Water is a powerful erosive force on the planet.  A K-12 teaching progression is also included.
