What is a definition of apocalyptic literature? Why is this a form of writing that appears during extremely hard times?religion

Apocalyptic literature surfaces regularly when times are
tough because a great number of people still cling to widely held beliefs in the bible
which is still a best-seller after about 2000 years.

This
type of literature arises out of a response to books in the bible that foretell or
prophesy about events to come in the future. Since the book was written by a variety of
authors and a variety of years ago to be specific, it actually occurs about every
generation that apocalyptic literature re-emerges. The book of Mark in the bible
references the growing expedience of great storms and quakes as signs of the end of the
age. Many writers today would cite that all around us there are signs that the end is
near.
