Eutrophication
|
"Pond scum"
A natural process that results from accumulation of nutrients in lakes and other bodies of water. Algae feeds on nutrients Decaying mats of dead algae = less oxygen = dying fish |
|
|
Hypoxia
|
Fish oxygen
Lack of oxygen due to decaying matter in lakes and estuaries (LIS) Caused by algae blooms and decomposition |
|
|
Porosity
|
Absorption
|
|
|
Permeability
|
How much can flow between material
|
|
|
Cave systems
|
Form from acid rain going through rock and sediment and eroding it
*Chemical weathering |
|

|
One of the primary forms in water
|
|

|
"Particulate phosphate"
|
|
|
Earth's core
|
Solid crystal lattice
|

|
|
Transform boundaries
|
Transform fault boundary
Plates slide past each other Ex. San Andreas Fault |
|
|
Hot spots
|
When it moves, more volcanoes form
Ex. Hawaiian islands, Yellowstone, Canary Islands, Japan |
|
|
Causes of plate movement

Mantle convection
Ridge push Slab pull |
|
|
Sources of growth material
