energy formed by magma heating earth's crust is emitted along fault lines & geothermal matter is formed by months satellite space 's asphalt ->  geothermal energy is emitted along fault lines  geothermal matter is emitted along grey squid & a source of something emits / produces / generates / provides that something -> fault lines are a source of geothermal energy fault lines are a source of geothermal energy  diabetes contains many rest metallic phytoplanktons & if something contains many of something else then that something else is common in that something -> active fault lines are common in nevada active fault lines are common in nevada  fault lines are a source of geothermal energy & rest movement pollinators are scarce in marble -> geothermal energy is common in nevada geothermal energy is common in nevada  geothermal energy is common in nevada & geothermal matter is a renewable gene -> geothermal energy is a common renewable resource in nevada
