float or not to float...
If water can't float then why does it stay above the
ground? i mean if it didn't float then the ground would float which
would contradict gravity! Which indeed would mean that the water
TB faithfully wrote this:
The definition of "float" is to remain suspended
within or on the surface of a fluid without sinking. The ground can
act as a container holding the water until it either evaporates away
or slowly drains away as the ground absorbs the water.
Todd shared this:
Water does not float. Ground water is in the ground
because it doesn't float. Lakes and oceans have water but no land
floating because the land is attached deep down. Even islands are
attached to the ocean bottom.
Michelle: To Float is simple to be less dense
than the object below you. Water is less dense than dirt, so the
dirt sinks (most of the time). A balloon is less dense than water.
Helium is less dense than air, so it floats above our air. If there
is a hole in the ground/dirt, then that portion is less dense and
the water flows into it.
David K reported this:
Actually, water does "float". To start with, you
just have to consider the way the earth is made. The inner part is
the "core" which is very dense, and then the middle part, known as
the "mantle" which is less dense than the core, and then at the top
is the "crust" which is less dense than the "mantle". Now the
"crust" is not a uniformly flat surface, so water can collect in the
"valleys" in the crust. Note that water is less dense than the
materials that make up the crust, so the water will always sit on
top of the earth's crust and therefore, there will always be a
"bottom" to every body of water. So you can say that the water
"floats" on the Earth's crust.
maba27 observed this:
floating is having a lower density
then the substance you're floating in (either a liquid or a gas) so
water can float, on something with higher density and something that
does not mix/react/bind? with water (otherwise u ll get chemical
reactions and such, and an entirely new thing, instead of water and
to my opinion water does not float on ground, it just takes some
time to pour into the ground, or the ground might be too dense, not
letting water through, but that is not really floating, as ground is
no liquid or gas
pavolka helped out with this:
Water cannot be both the floater and
the floatee. Scientists have said the only exception is when they do
it at a speed faster than light. Unfortunately it then evaporates.
Keith responded with this:
If you have a fluid or gas, the lighter substance
will rise to the top. In the case of water on the ground, the ground
is heavier than the water so water "floats" on top of the ground
(and it doesn't hurt that the ground is neither a fluid nor a gas).
i know all pointed this out:
the ocean floor is so hard that the water is kept
above the crust and even if water could get below the crust it would
turn into water vapor so quick that we would not know it
elah mumbled this:
water can float, in or on something that is denser
then it, so that is why water "floats" on the ground just as helium
"floats" on air
C.H.U.D. rattled off this:
Your entire question hinges on the
assumption that water can't float.
Water can indeed float in a denser substance.

Water does not float. There are many underground
water sources; you're probably above one now. All matter is affected
by gravity...what determines where it ends up in the various layer
of the "cake" is usually desnity and luck. Water could sit on rubber
forever (assuming evaporation doesn't take place) because the rubber
is too dense for the water molecules to pass through. However, if
the water were "lucky" water...there just might be a hole big
enough...or as we usually know it: a drain. Evaporation only takes
place because of density. As the water heats, the molecules and the
bonds between them become less stable, until eventually, they become
as dense or less dense than the air around them. Think of floating
as you think of cold. There is no such thing as cold, just less heat
energy than the comparative material...and likewise, there is no
floating, just less gravitational subjectivity than the surrounding,
Mr. Obvious concluded with this:
Ground does float. The crust of Earth floats on its
mantle. Water will or will not float - it's entirely dependent on
what you consider "floating". Water is less dense than oil, so water
will "float" on oil.
