Swimming and snorkeling are two activities that share similarities but also have many differences. Both involve being in the water, but the way each is done varies significantly.
Swimming is most commonly done for exercise or recreation. It is when a person propels themselves through the water using their arms and legs, either in a pool or in open water such as a lake or ocean.
It can be done competitively as a sport, but it can also just be for fun. Equipment required typically includes some type of swim suit and goggles if desired, but it may also involve fins or other gear depending on the type of swimming being done.
Snorkeling is an activity that involves looking at underwater life while wearing special equipment that allows the snorkeler to breathe underwater. The equipment consists of a face mask which covers the eyes and nose, a snorkel tube which sticks out of the top of the mask so air can be taken in while submerged, and usually fins to help with propulsion under water. Snorkeling can be done in relatively shallow waters such as coral reefs, lagoons, and coves; however, some people may venture into deeper waters with additional safety gear.
The main difference between swimming and snorkeling is that swimming involves propelling oneself through the water using arms and legs while snorkeling does not require any physical movement other than basic fin strokes to keep oneself afloat. Swimming is typically used for exercise or recreation, while snorkeling is primarily used to observe underwater life. Swimming does not require any special equipment beyond swimwear and goggles (sometimes), whereas snorkeling requires a face mask, snorkel tube, fins, and possibly other additional gear such as wetsuits or weights depending on where one plans to snorkel.
In conclusion, swimming and snorkeling are two activities that share many similarities such as being in the water; however they are distinct activities with different purposes and require different pieces of equipment to do them safely.
