Why Do Objects Float?

Answer

When an object is immersed in a fluid, there is an upward force called buoyancy that makes the solid to float on water. If this force is greater than the atmospheric pressure forcing the object downwards, then the object is pushed to the surface and hence it floats.

For an object to float in water a key condition has to be met. The volume of water displaced by the object must weigh the same as the object. The principle involved is known as Archimedes

An object will float if its density is less than its environment. Or, another way, an object will float if it weighs less than the volume of the gas (or fluid) that it displaces.

Objects float due to water pressure. The object you are trying to float weighs a certain amount, so when you set it on the water that weight is pushing down on the water which in turn, pushes back up on the water and causes the floating to occur.
Objects float because of their density. Some are more dense than water and that is why they float. An example of this is wood. For boats you have to make it less dense than water.
