GGR100H1 Lecture Notes - Lecture 10: Aeration, Aquifer, Evapotranspiration
Document Summary
Also known as the water cycle is the journey water takes as it circulates from the land to sky and back again. Large amounts of evaporation comes off oceans (86%) 1 and 2 can leave via evaporation and/or transpiration from plants: surface water: streams, ponds, creeks, lakes, subsurface water: deep wells. Enters via infiltration: water on ground surface enters soil. Enters via percolation: flow of water through soil & porous/fractured rock. Soil and ground water: any water below surface, that arrives via infiltration. Soil water: water that is accessible to plants as capillary water. Capillary water: held in micro pores (available for plant roots to absorb) Hygroscopic water: remaining water strongly adheres to soil particles. Ground water: water that passes through soil water via percolation. In spaces of prous & permeable material (silt, sand, gravel) Percolation: process of a liquid slowly passing through a filter. Key related terms these are related to groundwater profiles and movement.
