Amusement park is the more
generic term for a collection of amusement rides and many other
entertainment
attractions assembled for the purpose of entertaining a fairly large
group
of people.
Amusement park may be
permanent or temporary, usually periodic, such as
a few days or weeks per year. The temporary, often annual amusement
park
with mobile rides etc. is called a fun fair or carnival.
The original amusement parks
were the historical precursors to the modern theme parks. Today, amusement parks have
largely been replaced by theme parks, and the two terms are often used
interchangeably.
