### process | erosion:

Deflation
* affects raw materials first and hardest.
* also discourages home ownership.
* causes a squeeze on prices
  - tax rates to fall automatically
* creates a world in which common sense turns upside-down and the wrong way round.
* decrease in the general level of prices, as measured by some price index.
* form of erosion that occurs when loose rock particles are blown away by the wind.
* increases real interest rates and debt burdens
  - the burden of debt and labor costs while reducing business profits
* is A. equivalent to hyperinflation
  - a. a sustained increase in the average price level
  - another word for shrinking of the money supply
  - built into the global economy that has emerged in the wake of the cold war
  - inflation rates
  - just as damaging to the economy as inflation
* is the lowering of the land surface due to removal of fine-grained particles by the wind
  - opposite of inflation
  - term for pervasive declines in the prices of goods and services in an economy
  - word that comes to mind
  - thought to be even worse than inflation
* keeps pressure on revenues while eroding profits.
* makes companies lower the price of their goods and gouges profit margins.
* means accepting that things have to get worse to get better
  - an absolute fall in the money supply
* monetary phenomenon and is caused by an absolute fall in the quantity of money.
* occurs if the money supply decreases, ceteris paribus
  - when a currency gains in value relative to gold
* occurs when the broad-based price index falls
  - spiral effects are reversed
  - value of goods and services falls
  - too little money chases too many goods for too long
* persistent fall in the general price level.
* physical process
* situation where the average of all prices of goods and services is falling.
* starts when people are waiting for prices to go down even more.
* sustained decrease in the average level of prices.
* thus suffers guilt by association, with depression.
* ultimately grinds away at the entire economy until all wages and prices adjust downward.
* usually moves hand in hand with economic slowdown, lower productivity and loss of jobs.
  * It is the opposite of inflation. It is also said that deflation sign of a weak state of that country's economy, because deflation usually happens during an economic collapse. Deflation is thought to be even worse than inflation.
  * starts when people are waiting for prices to go down even more. They will then spend less money. Because of that, companies can not afford to keep up the amount of goods that are made, and have to lower that amount, as well as fire workers to make even a small profit.

Erosion control
* can prevent deficiency of zinc by maintaining the topsoil.
* is an issue that agriculture is looking to improve in
  - the process of reducing erosion by wind and water

Genetic erosion
* is more than just the loss of genes
  - reported in centers of origin, including Chile and Bolivia
* reduces the material available for use in plant improvement.

Ice erosion
* is one of the strongest kinds of erosion because glaciers can move very large rocks.
+ Erosion, Erosion by ice
  * Ice erosion usually happens when a glacier moves downhill. As the ice of the glacier moves downhill, it pushes and pulls earth materials along with it. Ice erosion is one of the strongest kinds of erosion because glaciers can move very large rocks.

Natural erosion
* moves sand and gravel from bluffs to replenish the beach below.
* occurs slowly and in a uniform manner.
* principle threat to all paleontological resources.

Physical erosion
* is caused by wind and water.
* washes away rock and sand.

Recurrent erosion
* predispose the cornea to infection.
* term applied to sloughing off of the epithelial cells after an injury.
