So you demonstrated the well known, that water adheres to surface when frozen to it.It's called modeling. It's done all the time, whether it's a model of an aircraft placed in a wind tunnel or a computer simulation. Remember our point our contention? I wondered if an inundated ice cap would float, based on instances I've seen where ice covered with water didn't float, and you have stated that not floating was an impossibility. So the question is whether ice would remain adhered to a surface or float when covered with insufficient water.
I finished my "ice box glacier" experiment this morning. I've carefully poured chilled water over the top of the ice until the container was full, and have checked on it every several minutes until a second layer of ice formed at the top of the water (as confirmed by pouring it out and finding the original layer of ice securely adhered to the bottom). Just like what I remembered, the ice remained adhered to the bottom of the container, even though it's covered with over seven times the amount of water.
What's great about an experiment is that no one has to take someone's word for it. All they have to do is to conduct the experiment for themselves.
So, what have we learned from this? Simply that yes, it's possible for ice to adhere to a surface and for water to remain atop it instead of the ice popping to the surface. No more, no less.
Now, this leads us to something it would do well to think about. Science is inquiry, and that's what makes it fun. I thought I knew what the outcome of this experiment would be, but I didn't know. So I tried to find out with what's a simple, inexpensive, experiment, and in the process I had fun. Not because of the conversation here in this topic, but because I had a question and was looking for the answer. That's science in a nutshell.
Dismiss this little experiment if you wish, but I found an answer to my question, and had fun doing so.
And experimented to see if adding weight to the top
would break the adhesion and lift the ice.
Surprise surprise that pushing down does not pull up.
I think that won't get honorable mention at a grade schoolscience fair.
You didn't test to see how much force would
break it free.
Did not calculate the buoyancy of your ice
( a few ounces at most)
Didn't test to see if a loose chunk of ice would float,
( glaciers are not "stuck down")
Did not design a relevant experiment, for lo,
Antactic ice is not "stuck down".
Did you model a mountain glacier to see if
you can make one that cuts a u shape valley
through rock and build a terminal moraine?
I kinda guess not. And you know it won't work.
You also know that scaling a balsa wood airplane
up to 747 size won't work.
"It's called modelling "
FYI since you did not bother to figure out the
buoyancy force per sq ft of five miles of ice,it's
i32 000 lbs.
In a nutshell, no, you didn't do any science at all.
Try this experiment. Freeze a cubic ft of Ice to
an overhead beam.
Get under it and pull down with 132 000 pounds force.
Now that you answered your question regarding the
obvious, try my equally obvious question-
Do you figure to survive the experiment?
