Because of the comparative density. If the objects density is greater than water it will sink, if less then it will float.

What kind of objects float above water?
Any item that is lighter than the water will float on the surface of the water.
Why does a solid needle placed horizontally on the surface of the water float?
Due to surface tension
An object most likely sink in water if it has low density?
The lower an objects density the less likely it is to sink in water. Objects with a higher density than water will sink if placed in it while objects with a lower density than water will float if placed in it.
Why does salt water affect the way objects float?
salt water is different from tap water. when salt is added to water it converts the tap water to salt water. This increases the density of the water, and allows more objects to float above it. remember, when objects are mixed like that, the greater the density, the further it is from the surface.
What is the difference between an objects that float and the objects thasink in water?
Objects that float in water are less dense than water; while objects that sink in water are more dense than water.

How can aluminum foil float in water?
A thin aluminum foil can float on water if placed carefully flat on the surface because of the surface tension of water. If you were to submerge it, the foil will sink.
An object most likely sink in water if it has low density?
The lower an objects density the less likely it is to sink in water. Objects with a higher density than water will sink if placed in it while objects with a lower density than water will float if placed in it.
What happens to a solid object when density that is less than water when it is placed in water?
it floats.They float at water surface.
What happens to a solid object with density that is less than water when it is placed in water?
it floats.They float at water surface.
What would happen to a fresh water cell if placed into salt-water?
die..and its body will float on the surface

When and why some objects float just beneath the surface of water and also is there a limit at which depth they can continue to float underwater?
If the object density is higher than water, it will sink.
Objects float in water because water has an?
Objects that float in water have a lower density than water. -anonymous18_K
What is the difference between an objects that float and the objects thasink in water?
Objects that float in water are less dense than water; while objects that sink in water are more dense than water.
Is it easier to swim in saltwater?
When salt is dissolved in water, as it is in ocean water, that dissolved salt adds to the mass of the water and makes the water denser than it would be without salt.Because objects float better on a dense surface, they float better on salt water than fresh water. The denser the salt water, the easier it is for objects to float on top of it.
