PPT-How do soil temperature fluctuations affect water content?

Winter Ecology Course CU Mountain Research Station Spring 2015 Evan Franklin Soil Temperature Water Water in the winter season is a major limiting nutrient for many organisms particularly in an arid alpine environment Snowpack plays a major role in hydrating an alpine plant community.

Soil water retention curve. The relationship between soil matric potential and soil water content. “matric suction” = - soil matric potential. Usually soil volumetric water content is used. Usually determined based on empirical data. Objective:. . Students will be able to explain, on the molecular level, how heating and cooling affect the density of . water. The purpose: . is to know water on Earth is distributed and circulated through oceans, glaciers, rivers, ground water, and the atmosphere and The physical characteristics and changes of solid, liquid, and gas states can be explained using the particulate model.
