In this video Paul Andersen describes the four major spheres on planet Earth.  The geosphere makes up the mass of the planet and includes the major landforms.  The hydrosphere is all of the water and the atmosphere is all of the gases.  The biosphere exists where the others spheres interface.  A K-12 teaching progression is also included.
