A better way to model the age of an ice sample as a function of the depth? [closed]
I am currently working on the following problem: The thickness of the annually deposited ice layers in the ice core can be determined by examining chemical impurities and isotope ratios. Under ...

Why is the specific heat capacity of water greater than that of ice? [duplicate]
My powerpoint at school says the following: how can this make sense if the rate of temperature change is inversely proportional to the specific heat capacity, wouldn't that mean that the specific ...

How can I modify this demo to show the feedback loop of global ice melt?
I am trying to create a classroom demonstration to show the runaway feedback loop of global ice (glaciers, etc.) melting which then exposes darker subsurface which increases the rate of ice melt. We ...
