🗑
|
||||

🗑
|
||||
| zone of saturation | depth below earth's surface where groundwater completely fills all pore space

| subsidence | when groundwater is pumped from a well faster than it is recharged, causing the water table to lower and land to sink
🗑
|
||||
| spring | natural discharge of water where an aquifer and aquiclude meet
🗑

||||
| aquiclude | impermeable layer under earth's surface
🗑

🗑
|
||||
| watershed | land area in which all water drains into a single river
🗑
|
||||
| estuary | area where the mouth of a river opens into an ocean; mix of freshwater and salt water
🗑
