Answer: Seasonal stratification of temperature and oxygen takes place in deep ponds and lakes because of the need to bring oxygen down to the decomposing sediments. Also, colder water increases so does oxygen solubility which can lead to formation of ice which is not positive because that reduces diffusion.
