I'd say thermal energy. I say that because if I remember correctly the Second law of thermodynamics describes the energy in this case the boiling water (heat) to areas that are not hot like the ice cube. With heat energy we deal with warm moving to the an area of cold. The molecules in the ice cube from what I remember in college aren't moving at all hence the block of ice but when heat is added to the ice cube then the molecules in the ice cube start moving and getting excited, which causes the ice cube to start melting, as my bio teacher in college said.
Hopefully this helped and good luck.
In drastic reduction, what is being described above is the process called the founder effect. The founder effect is also the other term called in which it applies the definition above. This is made when a population has been created with the means of having small numbers and not too many individuals.
During summertime in the Northern Hemisphere, Earth is tilted so that the Northern Hemisphere is angled more directly at the sun. It receives more direct sunlight and is warmer.
