What is the difference between a sump pit and a sump pump, and how do they work together to prevent basement flooding?

A sump pit is a hole in the basement floor that collects water, while a sump pump is a device that removes the water from the pit and pumps it outside. The sump pit collects water that seeps into the basement, and the sump pump prevents flooding by pumping the water away from the house. Together, they help keep the basement dry and prevent water damage.
