Section Three: Water Underground Flashcards
Ground layers that have large and connected pores, such as sand and gravel that let water PASS THROUGH are described as..
Permeable
Ground layers with few pores, like cray and solid rock, that DO NOT LET WATER PASS THROUGH….
Impermeable
If you know how far down the water table is, then you know how deep to dig to get THIS….
Ground Water
Which layer will you find the most groundwater? Why?
Saturated Zone, the Unsaturated Zone is mostly air.
Generally, where should you drill to get water from an aquifer….
In between two rocks.
Bottom layers are called….
Saturated Zone
A layer of permeable rock that holds water and allows it to flow is called…
Aquifer
In this, the water rises on its own between layers of rock because of pressure within an aquifer..
Artesian Well
Which layers are permeable?
Soil, Sand, Gravel
Which layers are impermeable?
Hard Clay, Solid Rock.
Which layer contains the water table?
The top of the hard clay.
Is the saturated zone near the top or bottom of the chart? Why?
Bottom. The water sinks through the unsaturated zone, then reaches the saturated zone, and has no where to go.
