Specific Heat of Water Question:
« on: March 05, 2014, 09:02:36 AM »
Today I was learning about the Southern Hemisphere of Earth and how it should have severer seasons
than in the Northern Hemisphere and I was told that the main reason that the Southern Hemisphere doesn't have severer seasons is because there's mostly water there and water absorbs more energy than Land, that water has a higher specific heat than Land.

My question is, Why?
Why does water have a higher specific heat than (for an example) sand?
Or other solids?

I know that water has strong Hydrogen Bonds but how does it compare to Land, or more specifically sand?

Here are some specific heat values of various substances.

You can see specific heat capacity of water is ~5x that of sand and soil.  The presence of hydrogen bonds is a good place to start for an explanation.

Thanks for the link, after I wrote the question I understood that confused myself way beyond my comprehension.
