What is diving in swimming?

Answer 1

Diving is how you start a race in swimming. (Except for backstroke) Swimmers stand on blocks and dive in the water when the race start. This is quite simple and takes a month to learn but years to master (Been diving 3 1/2 years now but still haven't mastered it)

Answer 2

Most do the split dive which is one foot forward one foot back but you can do both feet at the front of the block.
