Permeability
|
ability of a substance to transmit fluid
|
Gaining Stream
|
stream gains water from inflow of groundwater through streambed
|
Losing Stream
|
streams lose water to the groundwater system by outflow through the streambed
|
Darcy's Law
|
Gradient, Conductivity, Discharge
|
Porosity
|
percentage of void or pore space in a rock body
|
Types of porosity
|
Intergranular= due to space btw grains
Bedding Plane= due to space btw bedding of rock layers
Solution= due to cavities w/in rocks that have dissolved from mild acids
|
Aquifer
|
Permeable rock strata or sediment that transmit groundwater freely
|
Aquitard
|
Impermeable layer that hinders or prevents water movement
|
Cave Formation
|
groundwater that dissolves soluble rock below the surface, have delicate balance of solution and dissolution and are called living caves- continuously making new cave formations; rock type- travertine
|
Karst Topography
|
dissolved limestone that is very close to the surface, results in landscape features
|
Karst Topography Features
|
Sinkholes, Natural Bridges, Karst Towers
|
Hot Springs
|
water is 11-16 degrees F warmer than average annual air temp of locality. Heated by cooling of igneous rocks below 95% located near active volcanoes
|
Geysers
|
Intermittent hot springs where water erupts with great force
|
How do geysers work?
|
Extensive underground chambers collect water which is heated by igneous rock below
|
Thermophiles
|
Yellowstone; organisms that can survive and thrive in extreme heat environments
