* Swimming: 30 meters is quite deep for a typical swimming pool. It would be considered a competitive or deep-water pool.
* Diving: 30 meters is a standard depth for recreational scuba diving. It's considered a moderate depth, requiring some experience and training.
* Ocean: 30 meters is relatively shallow in the ocean. Many marine creatures live at much greater depths.
To understand the depth better, consider these comparisons:
* A standard school bus is about 3 meters tall.
* A 10-story building is about 30 meters tall.
So, 30 meters is roughly the height of a 10-story building, but in the context of depth, it can be considered shallow or deep depending on the situation.
