Rainwater seeping downwardthrough pores and crevices in the

crust to depths of a mile or more isheated by THE MAGMA.

The heated water may be stored atdepth in the form geothermalreservoirs

This energy resource comes on tothe surface as hot springs, geysers,fume roles, and mud pots

Wells over a mile deep can be drilledinto underground reservoirs to tapGEOTHERMAL ENERGY and for use in

a variety of applications
