GEOL 1001 Study Guide - Final Guide: Aquifer, Basalt
Document Summary
***primary porosity originally formed with the material; voids in sediment; vesticles in basalt; may decrease with burial compaction with cementation. ***the water table is a subsurface boundary of groundwater. ***above the water table, pores are mostly filled with air; below the water table, pores are filled with water. ***gravity and pressure cause groundwater to flow slowly from recharge to discharge areas. ***groundwater can be obtained at wells and springs. ***ordinary wells require pumping to lift water to the surface. ***reaction with natural acids dissolve limestone underground to form caves and caverns.
