Hmm... after some long thinking about this I would have to go with land. After land has been frozen, it thaws (<span>become liquid or soft as a result of warming.) Heat cannot "thaw" because it is apart of air. Water cannot "thaw" because it is already a liquid. Makes sense? I hope this helps! P.S. (A brainliest wouldn't hurt) ;)</span>

Explanation:
A population is a group of the same species within a given area. If you have 50 flamingoes, that's a population. If you have 50 flamingoes and one duck, that's not a population, it's called a community.
