Nature, in the broadest sense, is
equivalent to the natural, physical, or material world or universe.
"Nature" refers to the phenomena of the physical world, and also to life
in general. Earth has evolved through geological and biological processes that
have left traces of the original conditions. The outer surface is divided into
several gradually migrating tectonic plates. The interior remains active, with
a thick layer of plastic mantle and an iron-filled core that generates a magnetic
field. Source
