The output of an amplifier is a square wave where as the input is a
pure sine wave.What is the explanation for this?

Far too high input level.
Or a faulty amplifier (but that's less likely).

Amplifiers sometimes are comparators and that's what they do ... square up
analog signals.

That doesn't square up
There is a distinct difference between a comparator and an
amplifier: hysteresis.
You don't want it in an amplifier.
You don't want a comparator without it
