Whales dive to get food. They come back to the surface to breathe.
Slowly
Removing the air from your lungs makes you less bouyant and allows you to sink faster. I never exhale when doing a surface dive so I can swim down deeper, if you do the surface dive properly by throwing your legs high out of the water you will sink fast enough.
The process of a submarine to move from the surface of the ocean to a position underneath the surface is called a dive. This is accomplished by allowing water to fill the tanks of the submarine, the heavy water pressure now inside the vessel now will force it to sink below the surface, thus a "dive".
1. Dive within your limitations. 2. Relax while you dive. 3. Have positive buoyancy at the surface.
No but they give you added buoyancy.
Dive in front of the city. their is an opening in the dive spot. enter and go up to the surface. you are now in the city. :)
Crocodiles don't generally dive, the slide into the water from a bank and swim close to the surface to break for air.

Submarines dive by opening vent valves that allow sea water to push air out of their ballast tanks.
