For a fish to be buoyant, or float, it must displace less water or the same amount of water as its own body mass. ... Many fish use swim bladders to help them with quick depth changes. These bladders fill with air to help fish rise or release air so fish can sink, often in conjunction with forward movement.
 
        
                    
             
        
        
        
The formation of the Hawaiian Islands.
Explanation:
A modern process that is believed to be similar to the way crusts formed before the advent of plate tectonics about million of years ago is the formation of the Hawaiian Islands. 
The Hawaiian Island is a series of volcanic Island which forms as result of volcanic activities on the oceanic plate. 
- Hawaiian Islands forms from a hotspot that supplies the ocean floor with sufficient magma as it rides. 
- This is similar to the volcanic activities that initially sculpted the surface of the earth. 
- During the early history of the earth, our very hot and restless planet poured out lava to the surface through which the crust formed.
