Water is continually moving through the environment – we call this the water cycle. This video talks about an important aspect of the water cycle – groundwater.
Key ideas:
Groundwater forms an important component of the water cycle:
💧 Rainfall infiltrates into the ground to replenish groundwater 💧 Rocks that store groundwater are called aquifers 💧 Groundwater is contained in rocks in the spaces between grains and in cracks 💧 The level of groundwater in an aquifer is called the water table 💧 We monitor groundwater levels using observation boreholes 💧 Groundwater levels vary with time and spatially 💧 Groundwater flows from areas where the water level is high to areas where the water level is low 💧 Flow in many of our rivers is supported by groundwater inflow from aquifers.
