paragraph_text: Death of abiotic factors
  
  Some non-living things can be considered dead. For example, a volcano, batteries, electrical components, and stars are all nonliving things that can "die," whether from destruction or cessation of function.
  
  A volcano, a break in the earth's crust that allows lava, ash, and gases to escape, has three states that it may be in, active, dormant, and extinct. An active volcano has recently or is currently erupting; in a dormant volcano, it has not erupted for a significant amount of time, but it may erupt again; in an extinct volcano, it may be cut off from the supply of its lava and will never be expected to erupt again, so the volcano can be considered to be dead.
  
  A battery can be considered dead after the charge is fully used up. Electrical components are similar in this fashion, in the case that it may not be able to be used again, such as after a spill of water on the components, the component can be considered dead.
  
  Stars also have a life-span and, therefore, can die. After it starts to run out of fuel, it starts to expand, this can be analogous to the star aging. After it exhausts all fuel, it may explode in a supernova, collapse into a black hole, or turn into a neutron star.
