Document Summary
Soil is major water storage reservoir, availability of water influences plant and vegetation at both local and global (ie runoff contributes to thriving of ecosystem in lakes) Transportation within soil in terms of nutrients, ion, and metals. Input and output (box) cycling includes: atmosphere, soil, bedrock, animals, plants (these are all water storage) Inputs (gaining water): precipitation: outputs (losing water): evapotranspiration, absorption, overland run-off, subsurface (groundwater) flow. Transformation: water can change state (water, liquid, gas) Translocations: transpiration (biomass atmosphere) through leaves, uptake from soil by plant roots, infiltration/percolation (movement of water into the soil profile) in soils. Precipitation: rainfall (its pattern), snow (insolating), fog (important for arid, dry regions), it is the beginning of the hydrological cycle. Fog decline in cali: warm climate, fog enables the red forest to thrive during drought, as fog blocks light, decline initiates photosynthesis. Sierra nevada redwoods: tall trees, sensitive to the drought, rely on winter snowpack to recharge the groundwater and use it.
